1. Self-Tapping Screws for Metal
Recommended Types:
- Self-drilling screws (Tek-type) – for sheet metal, no need to pre-drill.
- Thread-cutting screws (Type F, 1, 23, etc.) – for thicker or harder metal.
Materials:
Our screws are made from SUS304, SUS316, SUS410, and super duplex stainless steel like S32750. This ensures they are strong and resist corrosion.

Our Advantage:
We provide custom screw lengths and head types, including hex washer, pan head, and countersunk, to meet your metalworking needs.
