Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw delivers exceptional engineering value through its 18-8 stainless steel composition and robust design. The coarse thread configuration provides superior holding power in structural applications, while the external hex drive ensures secure torque transmission during installation. The 80,000 psi tensile strength and Rockwell B70 hardness make it ideal for heavy machinery, construction equipment, and industrial frameworks where vibration resistance and long-term reliability are critical. The partial threading design concentrates clamping force where needed most, preventing joint loosening in dynamic load conditions common in manufacturing and infrastructure projects.

Specification Summary & Compliance

This hex head screw features precise Class 2A thread fit with 1/2"-13 UNC coarse thread specifications and 11" partially threaded length. Manufactured to ASME B18.2.1 standards, the screw ensures dimensional accuracy and interchangeability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and material transparency for global industrial applications.
