Professional Applications & Engineering Value

This 18-8 stainless steel thumb nut solves critical challenges in maintenance-heavy environments where corrosion resistance and quick disassembly are paramount. The UNC coarse thread configuration with Class 2B thread fit ensures rapid installation while resisting vibration-induced loosening in machinery, electrical enclosures, and structural assemblies. The standard wing nut profile with 1-1/2" width provides exceptional torque capability for manual operation in confined spaces, eliminating dependency on tools during field service or production line adjustments. Its right-hand thread direction maintains consistency with industrial standards, while the 3/4" height offers optimal finger clearance for comfortable, repeated tightening operations.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 2B thread fit tolerances per UNC standards. The 3/8"-16 coarse thread specification ensures compatibility with industrial fastening systems. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC requirements, confirms environmental and safety adherence for global industrial distribution.
