Professional Applications & Engineering Value
Engineered for demanding industrial settings, this 6-32 UNC thread socket head cap screw delivers robust fastening solutions where reliability is non-negotiable. The zinc-plated alloy steel material combats corrosion in moisture-prone or chemically aggressive environments, while the Rockwell C37 hardness and 170,000 PSI tensile strength prevent stripping and deformation under heavy loads. Its hex drive and coarse thread design facilitate rapid installation in machinery, automotive assemblies, and electronic enclosures, minimizing downtime. Ideal for applications requiring repeated maintenance, the screw’s Class 3A thread fit ensures precise engagement, reducing loosening from vibrations and enhancing overall structural integrity.
Specification Summary & Compliance
This socket head cap screw adheres to Class 3A thread fit for high precision and meets ASTM A574 specifications for consistent mechanical properties. It features a 6-32 UNC coarse thread with right-hand direction and is fully threaded for uniform load distribution. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for international industrial use.
