Professional Applications & Engineering Value
This 1/2"-20 UNF hex head screw delivers critical engineering advantages where vibration resistance and structural integrity are paramount. The fine thread spacing combined with Class 3A thread fit creates superior clamping force distribution, preventing joint failure in dynamic load conditions. The cadmium plated finish provides essential corrosion protection for outdoor equipment, marine applications, and industrial machinery exposed to moisture and chemicals. With its high tensile strength and Rockwell C26 hardness, this steel fastener maintains dimensional stability under extreme pressure, making it ideal for critical assemblies in aerospace, automotive, and heavy machinery where AN8-10A specifications are required for compliance and safety assurance.
Specification Summary & Compliance
Manufactured to inch system measurements with precision Class 3A thread fit tolerances per UNF standards. Features right-hand thread direction with fine thread spacing (20 TPI) on a 1/2" diameter shank. Complies with AN8-10A specifications for aerospace and defense applications, ensuring consistent quality and performance. The cadmium plating meets industry standards for corrosion protection while maintaining dimensional accuracy throughout the partially threaded design with controlled grip length for optimal fastening performance.
