Why are my Tapcons not grabbing?

The hole needs to be slightly smaller than the diameter of the fastener so that the threads of the Tapcon have something to grab into. If the masonry bit you use is too small you won't be able to drive the Tapcon in at all. If the masonry bit is too large, the Tapcon will not hold.

Why are my Tapcons not working?

Try getting as much dust out as possible or drill the hole deeper so the dust is below the depth of the length of the tapcon. Drilling deeper for tapcons is not a problem, drilling not deep enough will make the tapcon spin out therefore negating the fastening ability.

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 switch on the hammer drill must be in the hammer and rotation mode before starting to drill.

Why are my Tapcons stripping?

Over torquing may cause the tapped threads to strip out. To avoid over torquing, tighten with your hand for the last few turns. The threads will not tap into the base material properly when the masonry screw is installed in the hole too quickly.

How deep do you drill for Tapcons?

Using a carbide drill bit, drill a hole at least 1/4” deeper than anchor embedment. Clean hole with pressurized air or vacuum to remove any excess dust/debris. Using an impact wrench or manual torque wrench, insert anchor into hole and tighten anchor until fully seated. WARNING!

Never Use Tapcons Again!

Why are Tapcon screws blue?

Tapcon+ unmatched performance in concrete, block and brick applications make them an excellent alternative to expansion anchors, plugs, lag shields and have a blue corrosion resistant coating that enables them to withstand the harshest conditions.

How much weight do Tapcons 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.

Why are my concrete screws not sticking?

Over tightening/driving can result in the threads of the Tapcon being worn down as they spin against the concrete, some of the concrete will also be ground away. The result is a fastener that won't hold, just like over boring the whole with the masonry bit. So remember, snug it up, but don't over tighten.

Should I use water when drilling concrete?

Though you don't need to water down the concrete, the water will help to collect and remove the drilling dust, which can be hazardous to your health and "clog" the drill bit. The water can also help to keep your bit from overheating, which in turn helps keep the bit from shattering.

Can Tapcons be removed and reinstalled?

Tapcon Concrete Screws are removable, however it is not recommended to reuse the same hole because the cutting threads can compromise or destroy the holding power.

Can I use hammer drill with Tapcon screws?

The hole must be drilled using a hammer drill with a carbide tipped bit meeting ANSI standards. A bit that meets ANSI standards will ensure that the hole diameter will meet the requirements of the Tapcon®.

Do Tapcons work in brick?

The Tapcon concrete screw is suitable for use in a variety of base material, including brick and the mortar joints between the brick.

Are Tapcon screws any good?

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 long does concrete need to cure before drilling anchors?

You can drill the hole after 24 hours, but it would be better to wait an extra day. In addition, the insert you use to hold anything down will readily break free if you tighten it down, even after 2 days.

Why is my drill not making a hole?

The most common reason a drill won't penetrate a wall at all is because the drill is spinning in the wrong direction. If the drill bit enters the wall and then hits resistance, the typical cause is a metal plate or masonry obstruction.

Should I lubricate a masonry drill bit?

Lubrication can extend the life of the drill bit quite a bit if the lubrication is done whenever drilling holes. While drilling into glass or tiles the drill bit tip should never be hot and it should be almost warm. This lubrication can help drain away the burr from the drilling process.

Do I need to drill a pilot hole for concrete screws?

Do I need to drill a pilot hole for concrete screws? It is necessary to make a pilot hole for concrete screws. You should allow for a little extra depth to your drill hole to ensure that when the concrete screws are cutting threads there is enough room for any dust that might accumulate.

Are Tapcon screws better than anchors?

Tapcon and wedge anchors are pre-installed mechanical anchors that attach structural objects to concrete structures. However, the wedge anchor suits heavier-duty applications, vs the Tapcon anchor that typically serve lighter deployments. Another difference between them is in their fastening method.

How long should Tapcon screws be?

The maximum length would be 1-1/2" + 1-3/4"= 3-1/4", the maximum length of screw that can be used. 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.

How much weight can Tapcon screws hold in brick?

According to Tapcon single 1/4in Tapcon can be loaded 250lbs in tension or 620lbs in shear if embedded 1in in lightweight block.
