Professional Applications & Engineering Value
This 3/8"-16 UNC flat head screw delivers critical engineering advantages where flush surface mounting and structural integrity are paramount. The 18-8 stainless steel composition with passivated finish provides exceptional resistance to corrosion, oxidation, and chemical exposure in marine, food processing, and outdoor applications. The Class 3A thread fit and coarse UNC threading ensure rapid installation and superior vibration resistance in machinery, structural frameworks, and heavy equipment assembly. With 70,000 psi tensile strength and Rockwell B55 hardness, this fully threaded fastener maintains clamping force under dynamic loads while the 82° countersink angle creates secure, flush joints in metal fabrication and industrial manufacturing.
Specification Summary & Compliance
Manufactured to exacting inch system dimensions with Class 3A thread fit precision and UNC coarse threading (3/8"-16). Complies with ASME B18.3 mechanical specifications and maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features right-hand threading, standard flat head profile, and hex drive configuration for consistent performance across industrial applications.
