Professional Applications & Engineering Value
These 316 stainless steel flat head screws deliver exceptional corrosion resistance critical for marine, chemical processing, and food industry applications where moisture and corrosive agents are prevalent. The passivated finish enhances surface durability while maintaining the material's inherent anti-corrosive properties. Engineered with UNC coarse threads and Class 2A fit, these fasteners provide superior grip in various materials while resisting vibration-induced loosening. The fully threaded design ensures maximum engagement depth, making them ideal for applications requiring consistent clamping force across the entire fastener length. The 82° countersink angle and flat head profile facilitate seamless flush mounting in precision assemblies where surface protrusion is unacceptable.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit ensuring dimensional accuracy and interchangeability. Features 3/8"-16 UNC coarse threads with standard right-hand threading direction. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Mechanical properties include 70,000 psi tensile strength and Rockwell B80 hardness with complete passivated surface treatment for enhanced corrosion protection.
