Professional Applications & Engineering Value

This 7/8"-20 UNEF thin panel nut delivers exceptional performance in precision assembly applications where space constraints and vibration resistance are critical concerns. The black-oxide steel construction provides superior corrosion protection while maintaining the mechanical strength required for demanding industrial environments. The extra fine threading (UNEF) offers increased thread engagement compared to standard pitches, significantly enhancing resistance to loosening under vibration - a common failure point in machinery, electronic enclosures, and automotive assemblies. The thin hex profile allows installation in tight spaces where standard nuts cannot fit, while the external hex drive enables high torque application without damaging the fastener. These engineering features make it ideal for precision instrumentation, communication equipment, and industrial control panels where reliable, long-term fastening solutions are essential.

Specification Summary & Compliance

This panel nut features Class 2B thread fit per UNEF standards, ensuring precise dimensional accuracy and reliable thread engagement. The manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(a) for lead as an alloying element in steel and REACH (EC 1907/2006) standards (01/17/2023, 233 SVHC Compliant). The right-hand UNEF extra fine threading (7/8"-20) provides superior holding power in applications requiring fine adjustment and vibration resistance.
