Professional Applications & Engineering Value
These 316 stainless steel flat head screws deliver critical corrosion protection in demanding environments where moisture, chemicals, or salt exposure would degrade ordinary fasteners. The combination of fully threaded UNC coarse spacing and Class 2A thread fit ensures rapid installation while maintaining vibration resistance in assembly lines, electrical enclosures, and marine equipment. The passivated finish enhances surface durability without compromising the material's inherent corrosion resistance, making these Phillips drive screws ideal for maintenance-sensitive applications in chemical processing, food equipment, and offshore installations where disassembly for servicing is routine. The standardized 82° countersink profile guarantees flush seating in precision-machined components.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread tolerances for consistent fit. The 6-32 UNC coarse thread with right-hand direction provides reliable engagement in various materials. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The 316 stainless steel composition maintains mechanical properties including 70,000 psi tensile strength across the fully threaded 7/16" length.
