Professional Applications & Engineering Value

This nickel-plated brass thin hex panel nut delivers critical performance advantages in precision assembly applications where corrosion resistance and space constraints are primary concerns. The extra fine UNEF thread (3/8"-32) provides significantly increased thread engagement compared to standard pitches, making it ideal for thin panel applications in electronic enclosures, communication equipment, and instrumentation panels where vibration resistance is paramount. The Class 2B thread fit ensures consistent mating with corresponding male threads while accommodating minor variations in assembly conditions. The combination of brass material properties with nickel plating creates a durable fastener that resists galvanic corrosion when used with dissimilar metals, extending service life in demanding industrial environments.

Specification Summary & Compliance

This panel nut features 3/8"-32 UNEF extra fine threads with Class 2B thread fit per unified thread standards, ensuring precise dimensional tolerances for reliable performance. The thin hex profile measures 1/2" across flats with 3/32" height, providing optimal strength-to-size ratio. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) compliance for 233 SVHC substances as of January 2023. The right-hand thread direction and external hex drive design follow industry-standard configurations for panel nut applications.
