Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw in 316 stainless steel delivers critical performance advantages for demanding industrial applications. The external hex drive configuration enables high-torque installation in confined spaces, while the coarse threading provides superior resistance to vibration-induced loosening in machinery and structural assemblies. With its partially threaded design, this fastener offers optimal clamping force distribution across joined components. The marine-grade 316 stainless steel composition ensures exceptional corrosion resistance in chemical processing, marine environments, and outdoor installations where moisture and corrosive agents are present. These engineering features combine to create a reliable heavy-duty hex bolt solution that maintains integrity under sustained mechanical stress and environmental challenges.
