Professional Applications & Engineering Value

This 1/4"-20 UNC hex head screw delivers exceptional performance in applications where weight reduction and corrosion resistance are critical. The 2024 Aluminum construction provides excellent strength while minimizing overall system weight, making it ideal for aerospace components, electronic enclosures, and transportation equipment. The coarse UNC thread design ensures rapid assembly and superior holding power in softer materials or applications subject to vibration. With fully threaded construction and external hex drive, installation becomes more efficient while maintaining consistent clamping force across the entire fastener length. The combination of Rockwell B40 hardness and 30,000 psi tensile strength addresses common failure points in industrial settings, providing reliable performance where thermal cycling and mechanical stress are concerns.

Specification Summary & Compliance

This hex head screw features precise 1/4"-20 UNC coarse threads with Class 2A thread fit tolerance, ensuring consistent performance across industrial applications. The fastener meets RoHS 3 (2015/863/EU) compliance for restricted substance management and REACH (EC 1907/2006) standards for chemical safety. Manufactured to exacting dimensional specifications including 1/2" length, 7/16" head width, and right-hand thread direction, this screw delivers reliable performance in professional and industrial environments.
