Product Summary

Self drilling screw that drills, taps, and fastens in one operation. Type 3 point eliminates pre‑drilling in 2.8–5.3 mm steel. Hex washer head provides high torque without cam‑out. Zinc plated for indoor and mild outdoor use.

Product Applications

  2. One tool operation – drill and drive with a single impact driver

  3. Type 3 point matches common structural steel gauges (14–10 ga)

  4. Hex washer head prevents stripping and distributes load

  5. Full thread provides maximum pull‑out strength (>800 N)

  6. Case hardened – hard point (55 HRC), tough core (40 HRC)

  7. Zinc plating offers reliable corrosion protection

  8. Available in multiple lengths – 3/4″ to 6″

Product Functions
