Professional Applications & Engineering Value
This 3/8"-16 UNC hex head screw delivers exceptional engineering value across demanding industrial applications. The 18-8 stainless steel composition provides outstanding corrosion resistance in chemical processing, marine, and outdoor equipment where environmental factors degrade inferior materials. The flanged design with serrated locking features addresses critical vibration-induced loosening issues in machinery, automotive, and structural assemblies. With 100,000 psi tensile strength and Rockwell B100 hardness, this fully threaded screw maintains structural integrity under extreme mechanical stress while the coarse UNC thread ensures rapid installation in production environments. The external hex drive configuration accommodates standard tools for efficient maintenance and assembly operations.
Specification Summary & Compliance
This flanged hex head screw features precision 3/8"-16 UNC coarse threads with Class 2A thread fit tolerance for consistent assembly performance. Manufacturing adheres to standard inch system specifications with complete RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental regulation adherence for international industrial applications. The fully threaded design maintains uniform engagement across the entire 5/8" length while the 13/16" flange diameter provides optimal load distribution without additional components.
