Concrete screw anchors offer optimal performance in concrete, brick, hollow block and wood base material applications. The alternating high/low threads cut into the material and provide self-threading action and maximum holding power.
Concrete screws also feature a gimlet point, providing the “bite” for self-drilling into wood base materials, no need to pre-drill. Concrete screws are manufactured with a special coating that results in superior corrosion resistance.

How Does a Concrete Screw Anchor Work?
Screw anchors develop their load capacity by tapping into and creating an interlock between the anchor and the base material. An undersized hole is drilled into the base material in the most common systems. As the anchor is driven in, a keying/friction force is developed between the shank of the anchor and the base material. This type of anchor can be suitable for sustaining light to heavy-duty loads depending on the anchor design.
The Concrete Screw Anchor is the Industry's Most
Commonly Used Masonry Anchor.

Which concrete anchors are strongest?
The larger the diameter of the concrete screw anchor the higher holding values the anchor will have.
How to Install a Concrete Screw Anchor?
|Step 1 Using the proper drill bit size, drill a hole into the base material to the required depth, ho, which is a 1/4-inch deeper than the minimum embedment depth, hnom.||Step 2 Remove dust and debris from the hole during drilling (e.g. dust extractor) or following drilling (e.g. suction, forced air) to extract loose particles created by drilling||Step 3 Attach an installation socket tool for the selected anchor size to a percussion drill and set the drill to rotary-only mode. Mount the screw anchor head into the socket.||Step 4 Place the point through the fixture into the pre-drilled hole and drive the anchor in one steady continuous motion until it is fully seated at the proper embedment.|
What is a Secure Concrete Screw Anchors?
A secure concrete screw anchor also known as tamper-resistant screws or tamper-proof screw, are screws with a unique head that make it hard to remove without a secure driver that matches the secure screw head style. Making the standard Phillips, flat and hex head drives incompatible.
