Japan Miyagawa Adds 2 Series of Stainless Steel Self-drilling Screws

Miyagawa Corporation added "GRX Series" (with higher strength and hardness) and "SRX Series" (non-magnetic and able to drill sheet metal) to its stainless steel screw lineup for sale. "GRX" adopts martensite structure, demonstrating higher strength and hardness than those of "FRX" and "MRX", and making it possible to drill austenite stainless sheets which iron or SUS410 screws could not drill. "GRX" and "SRX" can fasten double layers of 6mm Stainless pipes or 6mm stainless sheets.
