Concrete Screws are also known as anchor screws that are designed for safe, secure, and quick fastening for various functions in Brick, concrete, and cinder block/masonry. These screws cut their threads, and when used in Brick, block, and concrete, they eliminate the requirement for an anchor in light or medium-duty applications.

The concrete screw is easy to use and remove; no hammering is required or must install a shield. These have been available in two head styles: hex head and flat head. Flat head screws have a Philips drive style, while hex heads can be slotted or unslotted head style. Concrete screws have been generally used for protecting medium-high load applications into concrete, hollow brick or stone brick, and solid Brick. Sometimes they have also been referred to as concrete anchors, concrete screws, and concrete bolt anchors.

They are designed to provide a strong and protective hold and to be quickly and smoothly installed, even into challenging substrates. They can also be fixed near the edge of the concrete, which risks distortion.

Fastening to concrete is unique compared to other fastening applications, such as fastening two metal parts together using a bolt, nut, or screw. Concrete screws are much tougher to install and use. Securing something to a solid base material is entirely different from any other type of fastening application.

All mechanical-type concrete screws work on the same basic principle. Drill a particular-sized hole, place the anchor, and stretch the anchor length more than the hole to make it difficult for the anchor to be pulled out of the hole. Concrete screws are designed to be placed into the hole in the concrete and not come out.
