Professional Applications & Engineering Value

This black-oxide steel thin hex panel nut addresses critical engineering challenges in panel assembly applications where space constraints and vibration resistance are primary concerns. The extra-fine UNEF threading (1/2"-28) provides significantly increased thread engagement compared to standard coarse threads, making it ideal for thin-section materials and applications subject to constant vibration or thermal cycling. The thin profile design (3/32" height) allows installation in confined spaces while the external hex drive ensures compatibility with standard wrenching tools, streamlining maintenance and assembly processes. Engineered for electronic enclosures, instrumentation panels, and aerospace components, this nut delivers reliable performance where precision threading and corrosion resistance are essential for long-term operational integrity.

Specification Summary & Compliance

This precision thin hex panel nut features 1/2"-28 UNEF extra fine threading with Class 2B thread fit per ASME standards, ensuring consistent dimensional accuracy and proper mating with Class 2A external threads. Manufacturing specifications include 5/8" width across flats and 3/32" height for the thin profile configuration. The component is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as an alloying element in steel and meets REACH (EC 1907/2006) requirements regarding Substances of Very High Concern (SVHC) as of January 17, 2023.
