Professional Applications & Engineering Value
Engineered for demanding industrial environments, this M3 PTFE plastic hex nut delivers critical performance advantages where metal fasteners fail. The PTFE material provides inherent chemical resistance against aggressive solvents, acids, and bases, making it ideal for chemical processing equipment, laboratory instruments, and semiconductor manufacturing. With thermal stability up to 500°F, it maintains structural integrity in high-temperature applications like oven assemblies, automotive under-hood components, and thermal processing machinery. The metric coarse thread design ensures rapid installation in production lines while the standard hex profile accommodates common wrenching tools, reducing assembly time and tooling costs. This combination of material properties and precision engineering solves critical challenges in corrosive, high-temperature, and clean-room environments where metal corrosion, galling, or contamination are primary concerns.
Specification Summary & Compliance
This metric hex nut features M3 coarse thread with Class 2B thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The nut measures 5.32mm across flats with 2.2mm height, manufactured from premium PTFE plastic with right-hand threading and external hex drive. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and substance restriction requirements for industrial components.
