Professional Applications & Engineering Value
This 316 stainless steel hex head screw delivers critical performance advantages in demanding industrial settings where corrosion resistance and structural integrity are paramount. The partially threaded UNC coarse thread design provides superior clamping force in heavy machinery, structural steel connections, and marine equipment, while preventing thread galling in stainless-to-stainless applications. With its external hex drive and substantial head dimensions, the fastener enables high-torque installation without stripping, making it ideal for maintenance operations and assembly lines where reliability is non-negotiable. The combination of 70,000 psi tensile strength and Class 2A thread fit ensures consistent performance in vibration-prone environments, from processing equipment to offshore installations.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 standards with Class 2A thread fit for precise dimensional tolerances. Features 1/2"-13 UNC coarse threads with right-hand direction and partial threading configuration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for global industrial applications.
