Professional Applications & Engineering Value

These M4 hex head screws in 316 stainless steel address critical challenges in corrosive and high-stress environments. The metric coarse thread with 0.7mm pitch enables rapid assembly in manufacturing lines while minimizing thread damage. With 100,000 PSI tensile strength and fully threaded design, they provide uniform clamping force across the entire 20mm length, preventing joint loosening in vibrating machinery. The external hex drive accommodates standard wrenches for maintenance accessibility in confined spaces. Ideal for chemical processing equipment, marine hardware, and food-grade machinery where corrosion resistance and regulatory compliance are paramount.

Specification Summary & Compliance
