Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 316 stainless steel flat head screws deliver exceptional performance in corrosive environments where standard fasteners fail. The combination of passivated finish and marine-grade stainless steel provides superior protection against chloride-induced stress corrosion cracking, making them ideal for chemical processing equipment, marine hardware, and food processing machinery. The UNC coarse thread configuration ensures rapid installation and reliable performance in soft materials or applications subject to vibration. With fully threaded design and Class 2A fit, these machine screws maintain consistent clamping force while the Phillips No. 2 drive offers familiar, efficient installation. The 82° countersink angle creates seamless flush mounting in precision assemblies where surface smoothness is critical.

Specification Summary & Compliance

This fastener maintains Class 2A thread fit per UNC standards with dimensional compliance to ASME B18.6.3 specifications. The manufacturing process ensures precise 1-3/4" length tolerance and consistent coarse thread spacing for reliable performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming restricted substance adherence. The right-hand thread direction and fully threaded construction provide standardized installation across industrial applications.
