Professional Applications & Engineering Value

This 316 stainless steel rounded head screw delivers exceptional performance in demanding industrial environments where corrosion resistance and mechanical reliability are critical. The passivated finish significantly enhances the natural corrosion resistance of 316 stainless steel, making it ideal for chemical processing, marine applications, and food processing equipment where exposure to moisture and aggressive substances is common. The precision Fillister head design with slotted drive provides superior torque transmission while the coarse UNC threading ensures rapid installation and reduced assembly time. With full threading along the entire 3/8" length, these screws offer maximum engagement strength and uniform stress distribution, preventing loosening under vibration and thermal cycling conditions common in industrial machinery and electronic enclosures.

Specification Summary & Compliance

This fastener maintains Class 2A thread tolerances per UNC standards with precise dimensional control. Manufacturing and quality assurance comply with ASME B18.6.3 specifications for slotted head screws. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The combination of 100,000 psi tensile strength and Rockwell B100 hardness provides reliable mechanical performance while the passivated surface treatment enhances durability in corrosive environments.
