Professional Applications & Engineering Value

Engineered for precision assembly, this 5-40 UNC coarse thread socket head cap screw delivers robust performance in machinery, automotive, and electronic enclosures where vibration resistance is critical. The 18-8 stainless steel material combats corrosion in humid or chemical-exposed settings, while the Class 3A thread fit minimizes backlash in high-cycle operations. Its fully threaded design and hex socket drive facilitate uniform tensioning in confined spaces, reducing installation time and preventing joint failure. Ideal for OEM and MRO applications requiring ASME B18.3 compliance, this screw ensures dimensional consistency across batch productions.

Specification Summary & Compliance

This socket head cap screw adheres to UNC coarse thread standards with a Class 3A thread fit for tight tolerances. Manufactured per ASME B18.3 specifications, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Dimensions include a 7/16" length, 0.205" head diameter, and 3/32" hex drive, ensuring compatibility with inch-system tooling.
