Professional Applications & Engineering Value
This M3 x 0.5 mm nylon 6/6 hex nut delivers critical engineering advantages where metal fasteners fall short. The nylon 6/6 plastic material provides inherent corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor elements. Its electrical insulation properties prevent current leakage in electronic assemblies, while the lightweight characteristic reduces mass in automotive and aerospace components. The coarse metric thread with Class 6H fit ensures secure fastening in vibration-prone environments, and the external hex drive style facilitates quick installation in tight spaces. These plastic metric fasteners solve common challenges of galvanic corrosion, weight reduction, and electrical safety in modern industrial designs.
Specification Summary & Compliance
This metric hex nut features M3 thread size with 0.5 mm pitch in coarse thread spacing and right-hand thread direction. Manufactured to Class 6H thread fit tolerance standards for precise metric threading compatibility. The standard hex nut profile measures 5.4 mm width across flats and 2.2 mm height. Compliant with RoHS 3 (2015/863/EU) regulations restricting hazardous substances, ensuring environmental safety in electronic and industrial applications.
