Self Drilling Screws / Tek Screws
Self drilling screws — tek screws — that drill, tap and tighten in a single action. TEK#1 to TEK#5 points, eleven head types, fifteen finishes.
What this group is for
A self drilling screw carries its own drill point, so it makes the hole, forms the thread and clamps the joint in one pass. Its case and core hardness both run higher than a self tapping screw of the same size for that reason, and every design is drill tested against a time limit before it ships.
- Points TEK#1 to TEK#5, plus winged and No.5 point variants
- M1.4–6.3 (0#–14#), 6mm–300mm; stainless line M2.9–6.3 from 13mm
- Carbon steel C1006–10B21 or stainless SUS302 / 304 / 305 / 316 / 410
- Hex washer, flat, pan, bugle, wafer, truss and Allen heads
