Professional Applications & Engineering Value
This zinc-plated steel panel nut with extra fine 1/4"-40 thread addresses critical challenges in panel assembly where precision and durability are paramount. The thin hex profile minimizes protrusion in confined spaces, while the Class 2B thread fit prevents cross-threading and ensures consistent clamping force in vibration-prone applications. Engineered for electronic enclosures, control panels, and instrumentation, its zinc plating provides a protective barrier against oxidation, maintaining electrical conductivity and mechanical integrity. The external hex drive simplifies maintenance and upgrades, making it an efficient solution for high-volume production lines and field service.
Specification Summary & Compliance
This panel nut features a 1/4"-40 extra fine UNS thread with Class 2B fit for precise dimensional accuracy, manufactured to inch system standards. The thin hex profile measures 5/8" width and 3/16" height, ensuring compatibility with standard wrenches. It is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006) regulations, meeting current industrial environmental and safety requirements for hazardous substances.
