Also know, what size drill bit do I use for a 3/16 Tapcon?

Tapcon® concrete screws tap threads into a predrilled hole in concrete, brick or block. The 5/32" bit is used for the 3/16" Tapcon® concrete screw and the 3/16" bit is used for the 1/4" Tapcon. These bits can be used for either the standard blue Tapcon or the stainless steel Tapcons.

Additionally, what size Tapcon do I need? The 3/16” tapcon uses a 5/32” bit, the 1/4” tapcon needs a 3/16” diameter bit, the 3/8” tapcon requires a 5/16”, the 1/2” tapcon requires a 7/16” bit, a 5/8”tapcon needs a 1/2” bit and the 3/4” tapcon requires the use of a 5/8” carbide tipped bit.

What makes Tapcons so popular is that you simply drill a hole using a hammer drill (if you don’t have one, see our best cordless hammer drill article to see which we think are the best) and then drive the Tapcon concrete screws in place. There are no inserts, so the anchors themselves are the very thing that bites into concrete, brick, stone, or masonry materials and provides a very secure connection. Tapcon concrete screws make for a very simple solution to a whole host of potential issues commonly faced by both homeowners and professionals. If you’re drilling a lot of holes, you may want to invest in a rotary hammer vs hammer drill to get better performance and faster drilling. The actual Tapcon concrete screws and anchors themselves are typically blue and the thread pattern is an alternating design that is made to draw the thread in and allow it to have an extremely strong hold.



Tapcon Concrete Screws – Sizes and Options

Tapcons are available in various lengths in both 3/16″ and 1/4″ diameters. They are also available as either hex washer heads or Philips flat heads. You can purchase them in small, medium, or large clamshell cases.

There are actually several styles of Tapcon. The 410 Stainless Steel Tapcon provides the ease of use and performance of a typical Tapcon, but with the 410 stainless steel composition. These are most commonly used on exposed areas like exterior shutters, screened enclosures, and decorative railing. The Tapcon SG (Storm Guard) is a modified design that is meant to be permanently attached and used to anchor metal or plywood panels to wood, block, or concrete. The Tapcon XL series is an oversized 5/16″ diameter anchor used for jobs that require additional strength.

Tapcon Concrete Anchors

We’ve used the standard blue Tapcons for years but thought it would be good to take a closer look at what makes them so unique and demonstrate just how well they do in a pinch. What was our “pinch?” A plumbing leak required we mount a replacement spigot to a block wall. To do this, we’d need something that could anchor a piece of pressure-treated (PT) lumber to the wall securely so that the new spigot would never torque or twist under use. Taking into consideration the 1×4 material we were using for our backing material, we grabbed a small box of 1/4″ x 2-1/4″ Tapcons for the job. With the 1/4″ Tapcons, they recommend a 3/16″ Tapcon drill bit. You can use that or a 3/16″ concrete hammer drill bit – which is what we utilized.

Installing Tapcons

Using a DeWalt hammer drill, we made quick work of the four holes, which we drilled to a surface depth of 1-3/4″. This gave us enough depth for the Tapcon to mount flush into the piece of pressure-treated wood and also sink a full 1-1/2″ into the concrete with an additional 1/4″ (as recommended) air gap after the end of the anchor. Once the holes were drilled out, we mounted our material and used a 9.6V DeWalt cordless drill gun to sink the Tapcons. Even with such a relatively low-powered drill, we were able to sink them without any difficulty. The Tapcon anchors simply bit into the wall and pulled themselves and the pressure-treated wood snug against the cinderblock, letting us know that a secure and stable connection had been made.

Conclusion

There is a lot of competition in the marketplace for Tapcon-type fasteners. You’ll see similar products marketed under the names of RuffNex, Kwik-Con, Caliburn (GRK Fasteners), and others. The basic thing you’ll want to look for is the material the fastener is made of, what kind of bit is used to drive it, and the pullout value (how securely it is rated to stay fastened). If you shop around, you can find Tapcons for $0.10/ea in quantity – far less than what you’ll find in your local home improvement store. If you’re planning a larger job or you intend to make frequent use of these anchors, be sure to buy them at the lowest cost possible.

Tapcon anchors are certainly one of the more popular (ie. well-marketed) products you can purchase, despite their premium cost. They are also a very unique (and of course proprietary) product that allows for extremely fast and reliable anchoring of materials to masonry products. If you drill the hole correctly – deep enough and with the correct diameter bit – these fasteners will simply work every time.

How much weight can a Tapcon screw hold?

1,360 lbs. *A safety factor of 4:1 or 25% of ultimate pullout/shear value is generally accepted as a safe working load. 340 lbs. 730 lbs.

Click to see full answer.


Regarding this, how long should Tapcon screws be?

The proper length could be either the 2-3/4" or the 3-1/4" length concrete screw. The 3-1/4" screw would be right at maximum embedment and depending on the abrasiveness of the base material, may be too long.

Also, how strong are concrete screws? Buy a variety of concrete screw lengthsIn hard, dense materials like concrete or stone, this minimum 1-in. screw embedment will work fine. But for maximum strength, use longer screws, up to 1-3/4 in. embedment, in soft brick or other less dense materials.

Thereof, how much weight can concrete anchors hold?

These concrete anchor bolts, or bolt anchors for wood, are available in several sizes and will hold up to 200 lbs. The sleeves pinch the sides of the predrilled hole and get tighter as you tighten the screw or bolt.

Do I need to pre drill for Tapcon screws?

Before a Tapcon masonry screw can be installed, a hole must be drilled into the masonry. Use a hammer drill to ensure that the hole has the proper tolerance. The carbide bit diameter required for the 3/16” screw is 5/32”. For the 1/4” screw a 3/16” carbide tipped bit must be used.

New Large Diameter Tapcon® Anchors Are Faster And Stronger Than The Competition

By Todd Fratzel on Uncategorized

Cracked And Seismic Approved

Tapcon Large Diameter Concrete AnchorSchaumburg, IL (July 2013) – ITW, the inventor of the original blue concrete screw, continues to innovate with the addition of three Large Diameter Tapcon® Concrete Screw Anchors that are faster to install and perform better than sleeve and wedge anchors, which translates to an increase in contractor productivity and profitability.

These new Made In The USA Large Diameter Tapcon® Anchors are available in 1/2” x 6”, 3/8” x 3”, 3/8” x 4”, 5/16” x 2” and 5/16 x 3” sizes, and their innovative technology means easier, faster and more secure (see “Proof in the Testing” below) anchoring into concrete, block and brick in a wide variety of residential, commercial and industrial applications.

The new Tapcon® anchors feature Advanced Threadform Technology™ which translates into 30 percent lower installation torque, and 20 percent more holding power. Large Diameter Tapcon® Anchors are 50 percent faster to install as they do not require assembling, driving, tightening and torqueing. Simply drill the hole and drive the Tapcon® Anchor. Large Diameter Tapcon® Anchors feature an induction hardened tip that is engineered to cut into concrete and brick, and increases pullout strength.

“Contractors will appreciate our new Tapcon® Anchors for their ease of installation,” said Laszlo Hullam, National Marketing Manager for Tapcon®. “Traditional anchors have many steps. First they have to be assembled, then you drill the hole, clean the hole, then pound the anchor in with a hammer and then tightened or torque down with a wrench. With Tapcon® Anchors, it’s a simple two step installation: you drill then drive the Tapcon® Anchor with an impact driver, that’s it. And with more contactors using cordless impact drivers, the reduced torque requirement will increase tool and battery life, adding to jobsite productivity.”

Another Key Feature: These new Tapcon® Anchors are cracked and seismic approved with 2012 building code compliance, as per ICC-ES ESR-2202, providing a level of assurance contractors appreciate when the Building Inspector arrives. In addition, Tapcon® offers the only 5/16” diameter seismic approved anchor on the market today. (Note: the 5/16” x 3” Tapcon® Anchor is the perfect anchor for installation of windows or doors into concrete or masonry where codes require cracked and seismic approval).

Other Tapcon® Anchor features that make this the “go to” anchor for professional contractors include:

  • Close-to-edge and close-to-anchor placement – unlike wedge and sleeve anchors, Tapcon® Anchors have no expansion or outward pressure so they can be placed closer in proximity to an edge or other Tapcon® Anchors.
  • Easy removal by simply unscrewing the anchor – traditional anchors cannot be removed.
  • Finished head – for a uniform profile and aesthetic appeal.
  • Blue Climaseal® coating – provides corrosion protection for outside applications.
  • Recommended for use in ACQ pressure-treated lumber.

Proof in the Testing

In comparative mechanical anchor testing done by the ITW Red Head Testing Laboratory, under International Accreditation Service listing TL-440, the ultimate tension load for the 3/8” Tapcon® Anchor was 10 percent higher than a wedge anchor and 28 percent higher than a sleeve anchor. The ultimate shear load for the 3/8” Tapcon® Anchor was 46 percent higher than a wedge anchor and 129 percent higher than a sleeve anchor.

The comparative testing of the 1/2” Tapcon® Anchor demonstrated that the ultimate tension load of the anchor was equal to a wedge anchor and 22 percent higher than a sleeve anchor. Upon review of the ultimate shear testing the 1/2” Tapcon® Anchor was 53 percent higher than a wedge anchor and 89 percent higher than a sleeve anchor.

Tapcon® Anchors are perfect for a wide variety of applications by contractors, builders and remodelers, including:

  • Sill Plates Door & window frames into masonr
  • Fences Jamb
  • Decks 2 x 4 lumbe
  • Wood headers Brackets for shelving into concrete and masonr

Large Diameter Tapcons

Using Large Diameter Tapcons To Secure Stairs To A Concrete Footing

Tapcon is a brand well known for it’s blue concrete or masonry screws that tap threads into concrete.  As a residential contractor I have always found Tapcons simple to use and a go to masonry fastener with excellent holding values.  If used properly, Tapcon masonry fasteners can work well in most masonry materials, such as mortar, brick, block or concrete.

The Tapcon brand masonry anchor is one of the most versatile products used for fastening to brick, block and solid concrete. Tapcons are available in two different diameters as well as in two head styles in order to meet a variety of different product installation requirements.

How They Work

Tapcon masonry screws work by tapping threads into the side wall of a pre-drilled hole in masonry. The key point that many a folk miss is the pre-drilled hole in the masonry must first be drilled using the correct size and properly  matched tolerance masonry bit.   Once the proper size hole is drilled the tapcon screw can be installed. As the tapcon is driven into the hole the lead thread taps threads cut away masonry material until the screw is threaded and securely embedded.

Large Diameter Tapcon Sizes

For many years tapcon has been available in numerous sizes  and are manufactured in two different head styles: the hex slotted washer head and the flat Phillips counter sunk.  Now they are available in larger diameter sizes.

A larger version is now available and available in 3/8”, 1/2″,  5/8″ and 3/4″ sizes are available.  These anchors come with or without a EnvireX coating which provides additional corrosion protection for outdoor applications.  They are also available in stainless steel.

Large Diameter Tapcon Features:

  • Available in 3/8″ and 1/2″ with and without EnvireX™ coating.
  • Available in 5/8″ and 3/4″ Sawtooth™.
  • Sawtooth™ design offers improved performance in large diameter holes.
  • Superior performance to wedge anchor.
  • Installs faster than wedge anchors or adhesive anchors.
  • Removable
  • Single piece design, no nut and washer to assemble
.
  • No special proprietary installation bits needed
.

Using Tapcons To Secure Stair Stringers:

We build and repair a lot of decks.   One weak spot we often encounter is the connection of the stair stringer to the concrete footing pad.  It seems alot of carpenters choose to nail a pressure treated cleat to the bottom of their stringers and then pour a pad the concrete up and over the p.t. cleat.

While that will certainly hold the stringers in place it does not allow you to later go back and cleanly repair or replace the stringers and often ruins the footing.

We use large diameter Tapcons to make this connection – they are corrosion resistant, ensure a strong connection and can be removed.  The problem with using Tapcons is that a lot of folks don’t know how to use them correctly.

Large Diameter Tapcon Concrete Tapcon Anchors

Common Errors Using Tapcons:

I’ve seen and heard of Tapcon failures in masonry and it has always come down to two factors:

  • Improper diameter pre-drilling.
  • Improper depth of fastener.
  • Wrong application

The minimum depth or embedment of a Tapcon screw is 1” and the maximum depth is 1-3/4”.  The threads on all Tapcon screws are a maximum length of 1-3/4” and longer screws are used depending on the thickness of the material it needs to travel through to fasten.

Pre-Drilling:

The bit diameter required for all Tapcon screws is slightly smaller than the designated diameter of the screw being installed and must also be drilled 1/4” deeper than the concrete screw will penetrate the base material. This allows space for the material that the threads remove as it taps the base material. If the hole is not drilled deep enough, the material may build up to the point where the Tapcon® screw will bottom out before it is able to secure the material being fastened. If this should happen, it is possible that the screw will over torque and shear off.

Proper Depth:

Unlike most other types of concrete screws where deeper embedment will provide better holding values, using deeper embedment with Tapcons will create an installation problem. The leading edge of these concrete screws are doing the cutting of the base material, whether it is concrete, brick or block. This cutting action deteriorates the leading edge of the thread and between 1” and 1-3/4” of the base material may deteriorate to the point where it is unable to perform.

To determine the longest Tapcon that can be used, add the thickness of the material to be fastened to the maximum embedment of 1-3/4″. These two measurements will give you the length of Tapcons to use.

Wrong Application:

If the material is too abrasive and the lead thread is worn down during installation, the Tapcon® screw will stop tapping threads. This continued torque on the screw can shear the Tapcon in half.  Applications like this may warrant the use of a  hammer drive or split drive concrete anchor.

Outdoor Considerations

Many folk do not know that the Tapcon blue color is a result of a special coating called Climaseal® which is a Thermosetting polyester coating designed to provide rust resistance.  This exceptional coating works well and makes the Tapcon screw an excellent choice for outdoor use.

When using Tapcons in outdoor applications, it is important to take into account many different environmental factors. These factors include: if the Tapcon will be in a moist environment, if it will be submerged in water or other liquids,  all of which increase the opportunity for rusting.

Installing A Tapcon Screw

  • Using a hammer drill and a carbide tipped masonry bit meeting ANSI standards, drill a hole with the required diameter of Tapcon masonry screw being installed.
  • Note – make sure that the depth of the hole will be a minimum of 1/2” deeper than the Tapcon concrete screw will penetrate.
  • Blow dust and debris out of hole.
  • Move the item being fastened and align the hole over the hole in the base material.
  • Insert Tapcon concrete screw through hole in the fixture and into the hole in the base material.
  • Fasten the Tapcon concrete screw tight against the surface of the fixture being installed. Make sure that the Tapcon concrete screw is not over-torqued to avoid stripping the threads in the base material and cause the Tapcon concrete screw to spin in the hole.
