Professional Applications & Engineering Value
This 316 stainless steel flat head screw delivers critical performance advantages in corrosive and high-stress environments. The combination of UNC coarse threading with Class 3A precision fit ensures vibration resistance and prevents loosening in machinery, electrical enclosures, and marine equipment. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making these hex drive screws ideal for chemical processing, offshore platforms, and food processing facilities where moisture and aggressive media are present. The 82° countersink angle and flat head profile allow for flush mounting in precision assemblies, while the fully threaded design maximizes connection integrity across the entire 5/8" length.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit and UNC coarse thread spacing (10-24 size). Dimensions include 0.411" head diameter, 0.127" head height, and 5/8" length with right-hand threading. Compliant with ASME B18.3 specifications for dimensional accuracy and mechanical properties. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
