Stainless Steel 420 Screws

Stainless Steel 420 Screws are a type of specialized fastener manufactured from martensitic stainless steel, which contains a higher carbon content (minimum 0.15%) compared to common austenitic grades (like 304 or 316). This composition allows the screws to be effectively heat-treated, resulting in exceptional high hardness and strength. The key advantage of SS 420 screws is their superior wear resistance and moderate corrosion resistance, particularly when polished and hardened, making them essential in environments where both mechanical durability and resistance to mild corrosive media are required. Zeron Fastners supplies a variety of these high-performance screws for diverse applications, including cutlery, surgical instruments, pump and valve parts, and general machinery where galling and abrasion are a concern.
