Concrete screws are hardened screws with a double lead—consisting of alternating raised and lowered threads with notches cut into the raised threads—and a diamond-shape, nail-type point. Special carbide bits are recommended for drilling pilot holes prior to driving concrete screws into masonry.
Also known as masonry screws, concrete screws cut their own threads when used in concrete, block, or brick. They can be used to secure wood, metal, or other materials, and eliminate the need for an anchor when used in light- to medium-duty applications.
Qualified for static and seismic loading conditions.
Thread design undercuts to efficiently transfer the load to the base material.
No special drill bit required; designed to install using standard-sized drill bits.
