Professional Applications & Engineering Value
These 316 stainless steel flat head screws deliver critical performance advantages in corrosive and high-stress environments. The combination of UNC coarse threading and Class 3A thread fit ensures vibration-resistant fastening in machinery, marine equipment, and chemical processing systems. The passivated finish enhances the inherent corrosion resistance of 316 stainless steel, while the undercut flat head profile with 100° countersink angle prevents surface protrusion in precision assemblies. Engineered for applications requiring 70,000 psi tensile strength, these fully threaded screws maintain structural integrity in temperature-fluctuating and chemically aggressive operational conditions where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit tolerance and UNC coarse thread specification (6-32 thread size). Features include 0.307" head diameter with -0.01" to 0" tolerance, 1/2" length, and 5/64" hex drive. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial fastener applications.
