Product Functions
Each screw integrates multiple critical components to perform its all-in-one fastening role.
-
Self-Drilling Tip: A precision-fluted point that cuts clean pilot holes in metal without wandering.
-
Thread-Forming Zone: Located directly behind the tip, it cold-forms perfect mating threads for maximum material engagement.
-
High-Strength Shank: The body provides the tensile strength and clamp force to securely join materials.
-
Optimized Drive & Head: Ensures efficient power transfer from the tool and provides a flush or bearing surface for a finished look.
