Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw in 18-8 stainless steel delivers critical engineering advantages for industrial applications where corrosion resistance and mechanical strength are paramount. The coarse thread design prevents cross-threading during high-speed assembly while maintaining excellent holding power in various materials. With 5" length and partial threading, it provides optimal grip range for structural connections in machinery, construction, and heavy equipment. The external hex drive ensures reliable torque transmission without stripping, reducing installation time and maintenance costs. These industrial hex screws solve common challenges of fastener failure in demanding environments, offering predictable performance and extended service life through controlled manufacturing to ASME B18.2.1 standards.

Specification Summary & Compliance

This hex head screw features precision Class 2A thread fit with 1/2"-13 UNC coarse threading in right-hand direction, manufactured to ASME B18.2.1 specifications. The fastener maintains dimensional accuracy across all critical parameters including head width (3/4"), head height (5/16"), and minimum thread length (1 1/4"). Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial applications.
