- Excellent vibration resistance prevents loosening in high-motion applications without requiring lock washers
- Wide thermal stability (-40° to 185°F) maintains performance across extreme temperature variations
- Exceptional electrical insulation properties for safe use in electrical and electronic assemblies
- Precision Class 2B thread fit ensures smooth engagement and reliable fastening performance
- Extra fine UNEF threading provides superior adjustment precision and load distribution
- RoHS 3 compliance meets international environmental standards for restricted substances
Professional Applications & Engineering Value
This 3/8"-32 UNEF Nylon 6/6 plastic hex nut delivers critical engineering advantages where metal fasteners fail. The Nylon 6/6 material provides inherent corrosion resistance in chemical, marine, and outdoor applications, eliminating galvanic corrosion concerns when mating with dissimilar metals. The extra fine threading offers precise adjustment capability ideal for instrumentation, optical equipment, and precision mechanisms where minute positional adjustments are crucial. As a non-conductive electrical insulator, it prevents short circuits in electrical enclosures and electronic assemblies. The standard hex profile with external hex drive ensures compatibility with common tools while the thermal stability range maintains integrity from freezer applications to elevated temperature environments.
Specification Summary & Compliance
This inch-system fastener features 3/8"-32 UNEF extra fine threading with Class 2B thread fit for consistent engagement. The standard hex nut profile measures 9/16" across flats with 11/32" height. Manufactured to applicable UNEF thread standards and compliant with RoHS 3 (2015/863/EU) environmental directives, ensuring no restricted substances are present. The right-hand thread direction and external hex drive provide industry-standard installation compatibility.
