Professional Applications & Engineering Value
This M8 coarse thread hex nut delivers critical performance advantages in demanding industrial settings where temperature extremes and chemical exposure compromise conventional fasteners. The PTFE plastic construction maintains dimensional stability under thermal stress up to 500°F while providing inherent corrosion resistance, eliminating galvanic compatibility concerns in mixed-material assemblies. The Class 2B thread fit ensures precise engagement with mating components, reducing installation time and preventing thread damage in high-volume production environments. Particularly valuable in chemical processing, food manufacturing, and electrical applications, this metric hex nut combines regulatory compliance with engineering-grade performance where non-conductive, non-corrosive fastening solutions are essential.
Specification Summary & Compliance
This metric fastener features M8 coarse threading with Class 2B thread fit per ISO standards, ensuring proper clearance and engagement with Class 2A external threads. Dimensions include 12.73mm width across flats and 6.4mm height with standard hex profile. The nut conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, making it suitable for regulated industries. Manufacturing follows metric system specifications with right-hand thread direction and external hex drive style for universal tool compatibility.
