Professional Applications & Engineering Value

This 1/2"-20 UNF hex head screw delivers critical performance advantages in demanding industrial settings. The 18-8 Stainless Steel composition provides exceptional corrosion resistance, making it suitable for chemical processing, marine applications, and outdoor installations where environmental factors degrade ordinary fasteners. The UNF fine threading with Class 2A fit ensures precise engagement in tapped holes, reducing the risk of cross-threading while maintaining vibration resistance. The external hex drive combined with the substantial 3/4" head width enables high-torque installation without stripping, crucial for structural assemblies and heavy machinery. The partially threaded design concentrates the clamping force where needed most, preventing joint loosening under dynamic loads while the 7" length accommodates thick material stacks in construction and manufacturing applications.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 2A thread fit tolerance ensuring consistent performance across applications. The UNF (Unified National Fine) thread standard guarantees compatibility with corresponding nuts and tapped holes. This hex head screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial use without hazardous substance restrictions. The combination of Rockwell B70 hardness and 80,000 psi tensile strength meets rigorous mechanical requirements for structural fastening applications.
