Built to cut deep clean grooves into pre-drilled holes in many masonry materials such as solid concrete, block, and brick.
A serrated pattern on the point and threads of a screw. These serrations help the screw start quicker, reduces splitting, and requires less torque.
Single lead thread with a wide spacing for superior holding in softwoods and particle boards.
A screw point that drills a hole for the screw and eliminates the need for pre-drilling.
Built with a milled slot running from the point to past the heel. Acts like a drill to help cut wood fibers and reduce splitting.
