Professional Applications & Engineering Value
Engineered for demanding industrial environments, this 1/4"-20 UNC hex head screw in 316 stainless steel delivers critical corrosion resistance where exposure to chemicals, saltwater, or extreme temperatures would degrade ordinary fasteners. The fully threaded coarse spacing and Class 2A thread fit enable rapid assembly in structural frameworks, machinery, and marine equipment while minimizing galling. With external hex drive design, installers achieve high torque transmission without stripping, making these industrial hex screws ideal for maintenance-intensive applications requiring repeated disassembly. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures long-term fastener integrity in vibration-prone systems, from processing equipment to offshore installations.
Specification Summary & Compliance
This 2" length hex head screw maintains precise Class 2A thread tolerances per UNC standards with 1/4"-20 coarse thread configuration. Manufacturing adheres to ASME B18.2.1 dimensional requirements, while material composition and finishing processes comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, including SVHC compliance as of June 2023.
