Professional Applications & Engineering Value

This 18-8 stainless steel thumb nut solves critical challenges in maintenance-heavy environments where frequent adjustments are necessary. The right-hand UNC coarse thread design enables rapid installation while the 31/64" base diameter provides stable seating on mating surfaces. Engineers specify this wing nut for electrical enclosures, machinery guards, and production jigs where corrosion resistance prevents seizure in moist conditions. The Class 2B thread fit maintains precise tolerances across temperature variations, eliminating the need for lock washers in moderate vibration applications. Its 5/8" height offers sufficient thread engagement while remaining compact for space-constrained assemblies.

Specification Summary & Compliance

Manufactured to UNC 1/4"-20 coarse thread specifications with Class 2B thread fit ensuring dimensional accuracy per ASME B1.1 standards. The standard wing nut profile (1 1/8" width × 5/8" height) provides ergonomic handling. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates, guarantees safe use in regulated industries worldwide.
