Professional Applications & Engineering Value

This 3/4"-16 UNF hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 316 Stainless Steel composition provides exceptional performance in chemical processing, marine hardware, and food processing equipment where exposure to chlorides and acidic environments would compromise ordinary fasteners. The fine UNF thread configuration offers superior resistance to vibrational loosening compared to coarse-thread alternatives, making it ideal for precision machinery, pump systems, and structural assemblies requiring maintained clamp force. With fully threaded design and Class 2A thread fit, this fastener ensures maximum thread engagement and consistent installation torque across the entire 2" length, eliminating weak points in critical connections.

Specification Summary & Compliance

This hex head screw features 3/4"-16 UNF fine threads with Class 2A thread fit per ASME B18.2.1 specifications, ensuring precise dimensional accuracy and interchangeability. Manufacturing compliance includes ASME B18.2.1 standard for hex head cap screws, along with environmental regulations RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance. The fastener delivers consistent mechanical properties with 70,000 psi tensile strength and Rockwell B70 hardness throughout the 316 Stainless Steel construction.
