Professional Applications & Engineering Value
This 4-40 UNC coarse thread socket head nut delivers critical engineering solutions where space optimization and precision fastening intersect. The alloy steel construction provides exceptional shear strength and fatigue resistance for demanding applications in machinery, automation systems, and electronic enclosures. The partially threaded configuration prevents binding during installation while maintaining full thread engagement depth. With its hex drive design and compact 0.17" height, this nut excels in confined assembly environments where traditional wrenches cannot operate. The UNC coarse threading ensures rapid installation and superior vibration resistance in high-cycle manufacturing applications, making it ideal for precision equipment maintenance and OEM production lines requiring reliable, repeatable fastening performance.
Specification Summary & Compliance
This socket head nut maintains Class 2B thread fit tolerances per UNC standards with precise 4-40 coarse threading. Manufacturing specifications include 0.18" OD, 0.17" height, and compatibility with 0.202" hole diameters. The product fully complies with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as steel alloying element and meets REACH (EC 1907/2006) requirements current through January 2023 SVHC list. Thread depth is engineered at 0.08" for optimal engagement in standard industrial applications.
