Key Features & Benefits at a Glance
- Superior corrosion resistance with nickel-plated brass construction, ideal for humid or chemically exposed environments
- Space-saving thin profile (5/64" height) enables installation in tight panel assemblies without compromising strength
- Precision UNEF extra fine threading (1/4"-32) provides enhanced vibration resistance and secure fastening in delicate equipment
- Reliable Class 2B thread fit ensures smooth assembly and consistent torque performance with standard male threads
- External hex drive design allows for quick installation using common wrench tools, reducing assembly time
- Regulatory compliance with RoHS 3 and REACH standards guarantees safety for industrial and electronic applications
- Durable nickel plating maintains electrical conductivity while providing long-lasting surface protection
Professional Applications & Engineering Value
This nickel-plated brass panel nut solves critical challenges in electronic enclosures, instrumentation panels, and communication equipment where corrosion resistance and reliable grounding are essential. The UNEF extra fine thread (1/4"-32) delivers superior holding power in thin materials, preventing loosening under vibration - a common failure point in industrial controls and aerospace panels. The thin hex profile maximizes space efficiency while the external hex drive ensures tool accessibility in confined assemblies. Unlike standard nuts, this specialized panel nut maintains electrical continuity through its brass core while the nickel plating resists galvanic corrosion when mated with dissimilar metals.
Specification Summary & Compliance
Manufactured to Class 2B thread tolerances for consistent fit with standard UNEF threaded components. Dimensions include 1/4"-32 extra fine thread with right-hand direction, 5/16" width across flats, and 5/64" height. Compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations regarding SVHC substances. Meets industry standards for panel nut applications requiring precise thread engagement and environmental durability.
