Professional Applications & Engineering Value
Engineered for high-performance industrial fastening, this 10-32 UNF socket head cap screw addresses critical challenges in machinery, automotive, and aerospace assemblies. The zinc-plated alloy steel construction combats corrosion while maintaining Rockwell C37 hardness, preventing wear in dynamic environments. Its fine thread spacing and Class 3A thread fit deliver superior vibration resistance and sealing capabilities, reducing maintenance needs in precision systems. The hex drive enables secure installation in confined spaces, making it ideal for high-strength applications where reliability and compliance with ASTM A574 are paramount.
Specification Summary & Compliance
This screw adheres to Class 3A thread fit for precise UNF thread tolerances, with a minimum thread length of 1" and partial threading. Manufactured per ASTM A574 specifications, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental and safety standards. The inch-based dimensions, including 2-1/2" length and 5/32" hex drive, support consistent performance in regulated industrial applications.
