Tornilleria Cabeza Zinc Alum

Seld Drill 3/8” HWH, Zinc aluminum capped drill screw

- The most widley used zinc aluminum capped fastener in the industry.
- Precision cold forger assuring superior point strength and the fastest drilling time performance trhough high strength steel and nested purlins.
- Designed and enineered to have low driving and thread engagement torque to prevent damage to the cap during installation while providing maximum  clamp load.
- Integral cupped Hex Washer Head can never red rust.



APPLICATION

Metal to metal

Drilling capacity: .035 - .210
Thickness is based on normal, single thickness purlin/girt or multiple material thickness combined for total.

Min projection: 3/16” of threads below substrate.
