Concrete Screws

Concrete Screws provide a secure fixing into a wide range of materials since they are suitable for concrete, solid red brick, stucco, hollow blocks, natural stone, etc.

Concrete screws provide fast, secure anchoring, utilizing a hardened screw with specially fashioned high and low threads that cut into the properly sized hole and thread into cement. Installation is accomplished through the use of specially designed carbide bits, and becomes an even faster operation when used with the concrete screw drive tool. The concrete screw system eliminates the need for plastic or lead anchors in medium and light duty applications, and can be removed if desired without excessive damage to the surrounding surface.

Concrete screws are the perfect fastener for speedily anchoring light- to medium-weight objects to concrete. Just as with any concrete anchor, you still have to drill a hole in the concrete. But with a concrete screw, the hole can be smaller and you don't need a separate anchor. You drive the screw right through the material you're attaching and into the concrete.

Working with Concrete Screws

Select a screw length to penetrate the concrete at least 1 in. Add 1 in. to the thickness of the material you're attaching to get the minimum length of screw needed. In hard, dense materials like concrete or stone, this minimum 1-in. screw embedment will work fine. But for maximum strength, use longer concrete screws, up to 1-3/4 in. embedment, in soft brick or other less dense materials. You may have to experiment with a few different lengths to find a screw that you can drive fully and that holds securely.
