Professional Applications & Engineering Value

This 1-72 UNF fine thread socket head cap screw is engineered to address critical challenges in precision assemblies where space is limited and vibration resistance is paramount. Manufactured from 18-8 Stainless Steel, it provides excellent corrosion resistance, reducing maintenance needs in applications exposed to moisture or chemicals. The Class 3A thread fit and fine thread profile ensure tight tolerances, preventing loosening in high-vibration environments like machinery, automotive subsystems, and electronic enclosures. The hex drive socket head allows for high torque application in confined spaces, making it a reliable choice for industrial fasteners in aerospace, medical devices, and precision instrumentation. Its fully threaded design offers uniform clamping force, enhancing joint integrity where consistent load distribution is required.

Specification Summary & Compliance

This screw adheres to ASME B18.3 dimensional standards, ensuring precise thread geometry and Class 3A thread fit for superior accuracy. It features a UNF fine thread (1-72) with a right-hand direction and is fully threaded for consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms its suitability for environmentally regulated and international markets, supporting safe and sustainable manufacturing practices.
