Professional Applications & Engineering Value
These Black-Oxide Alloy Steel Socket Head Cap Screws with Torx Plus IP45 drive are engineered to solve critical fastening challenges in heavy-duty industrial environments. The combination of 180,000 psi tensile strength and Rockwell C39 hardness ensures reliable performance under extreme mechanical stress, while the black-oxide surface treatment provides essential corrosion protection in harsh operating conditions. The 5/16"-18 UNC coarse threads with Class 3A fit deliver superior vibration resistance and precise alignment in machinery, automotive, and construction applications where failure is not an option. The Torx Plus drive system significantly reduces tool slippage and fastener damage during high-torque installation, making these screws ideal for assembly lines requiring consistent, repeatable fastening operations.
Specification Summary & Compliance
This socket head cap screw features precise Class 3A thread fit with UNC coarse threads measuring 5/16"-18. Manufactured to ASTM A574 specifications with complete RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental responsibility and regulatory adherence. The fastener maintains dimensional accuracy with a 1 1/2" length and fully threaded design for consistent performance across industrial applications.
