5.5 x 25 Light Section Hex Head Self Drilling Screw (Sold Individually)

Tek screws have a self-tapping thread, and a drilling point. The combination of both provides you with a fast and efficient means of attaching two materials together. Depending on which tek screws you have, the material thicknesses and types will vary from application to application, but all tek screws will work the same way – they will pilot drill through the first material, before drilling and fastening into the second material.
