Professional Applications & Engineering Value

This PTFE plastic hex nut delivers critical performance advantages in demanding industrial settings where conventional metal fasteners fail. The M5 coarse thread configuration combined with Class 2B thread fit provides reliable engagement in high-vibration applications while accommodating thermal expansion. Engineered for chemical processing, food manufacturing, and semiconductor equipment, the white PTFE material offers non-contaminating properties and exceptional resistance to aggressive chemicals, solvents, and extreme temperatures. The external hex drive design ensures compatibility with standard tools, streamlining maintenance procedures in confined spaces. This nut solves corrosion-induced failure points while maintaining 500°F temperature resistance in thermal cycling environments.

Specification Summary & Compliance

This metric hex nut features precise M5 coarse threading with Class 2B thread fit tolerances, measuring 7.78mm across flats and 4.4mm in height. Manufactured from high-purity PTFE plastic with right-hand thread orientation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
