Q: What material are these screws?
A: They are carbon steel with a mill finish.
Q: Which length should I choose?
A: Use 1-1/4 in. for thinner panel fastening and 3 in. when more embedment or thicker assemblies are involved.
Q: Why choose the washer version?
A: The with-washer variant adds a bearing surface at the head, which is useful where load spread or sealing is important.
Q: What head styles exist in this line?
A: Hexagon, pan, countersunk, round, truss and half countersunk heads are listed for the Tek 5 screw line.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Self-drilling Tek screws save real time on metal-to-metal fastening because they drill, tap and fasten in one pass. Pick the 1-1/4 in. screw for standard panel laps and the 3 in. for thicker assemblies or deeper penetration, and use the washered version where you want a wider bearing surface. Match the head style and driver to the panel system you are fastening.
Wear eye protection and gloves when driving self-drilling screws; screw points and cut ends are sharp.
