Tapcon Masonry Screws FAQ

What are Tapcon masonry screws?

Purchase Tapcons

Tapcon masonry screws are made for light duty fastening. They are manufactured with special threads that will tap into a predrilled hole in masonry material, such as concrete, concrete block, and brick.

How do they work?

These screws embed into masonry by “tapping” the threads through the material surrounding the hole. The tapping of the threads into installation materials requires the threads to be properly cut.

When should I use them?

These screws are made for light duty fastening into materials like concrete, brick, block, and mortar joints.

How much weight does a stainless steel screw hold?

The stainless steel screw has different holding values for different materials and different embedment depths.

How do I install a Tapcon masonry screw?

Installation is easy. Prepare your materials, consult the technical information to determine what size hole to drill, and drill the hole. Install the fastener through the item being fastened, and tighten. For more detailed instructions, please visit our Tips & Tricks page.

How deep do I drill the hole?

The hole drilled into the base material should be at least 1/2-inch deeper that the depth that the screw will be embedded.

Can I put this screw into brick or block?

Yes, it can be used in concrete brick, block, or mortar joint.

Do I need to use a Tapcon installation tool to drive the screw?

No. It can be installed with a standard nut driver or Philips head bit tip

What size hole do I drill for the 1/4” screw?

The 1/4-inch screw requires a 3/16-inch hole in the base material.

Do I have to use a hammer drill when I am drilling a hole for the installation?

A hammer drill is recommended when installing the screw. The use of a hammer drill will create a hole that best meets the hole tolerance requirements.

Why is the stainless steel Tapcon more expensive than other concrete screws?

The cost of the raw material, the manufacturing cost, and the total production expense are all factored into the higher price.

Are stainless steel Tapcon masonry screws still made in America?

Yes. The Tapcon brand concrete screws are still made in the USA. Many other brands are not made in the USA, and they do not meet the same specifications.

Are these cement screws removable?

Yes, they are removable from the hole in which they are installed. However, reusing the screw in the same hole is not advisable because the holding values may be decreased or non-existent.

Why do 410 stainless steel screws stick to a magnet?

The screws are manufactured out of stainless steel with nickel added. This makes the threads hard enough to cut the masonry, and also results in creating a magnetic force.

Why can’t I install this concrete screw deeper than 1-3/4”?

The maximum embedment is 1-3/4”. At deeper than 1-3/4”, the lead thread may stop tapping the base material and may cause the screw to get bound in the hole or have the head sheared off.

Why is the screw not fully threaded?

It is not fully threaded because the maximum embedment in the base material is 1-3/4 inches. The thread length on the screw equals the maximum embedment depth.

Is the stainless steel hex head screw available in 3/16” diameter?

No. The flat countersunk Phillips head is the only type of this screw available in the 3/16 diameter.

Is this anchor available in any lengths shorter than 1”?

No, the shortest stainless steel screw available is 1-1/4”.

What is the Climaseal® on the stainless steel screw?

The stainless-steel screw is coated for extra rust resistance. Climaseal is a high-quality metal filled thermoset coating. Climaseal has been uniquely formulated to react and form a complete, long life protection that provides the optimal corrosion resistance properties. Climaseal is self-sacrificing to the base substrate if penetrated or damaged. Fasteners coated with Climaseal exhibit excellent resistance to most forms of abrasion and torque.

Can I get stainless steel Tapcons in blue?

No, the stainless steel Tapcon screws are available in a silver color only. The blue colored screws are standard carbon steel.
