Professional Applications & Engineering Value
This M20x2.5 Class 8 flange lock nut delivers exceptional engineering value through its integrated design that combines the load-bearing capacity of a flange nut with the vibration resistance of a nylon insert lock nut. The 42.8mm flange diameter provides substantial bearing surface, distributing clamp load effectively to prevent damage to connected materials while eliminating the need for separate washers. Manufactured from zinc-plated steel, this fastener offers reliable corrosion protection for industrial equipment, machinery, and structural applications where vibration resistance is critical. The metric coarse threads (M20x2.5) ensure quick assembly and disassembly while maintaining the integrity of the connection through the nylon insert locking mechanism, which creates consistent friction against the mating bolt to prevent loosening under dynamic loads.
Specification Summary & Compliance
This flange lock nut features precision M20x2.5 coarse threads with Class 6H thread fit according to DIN 6926 manufacturing standards. The external hex drive (30mm width) and 24.8mm height provide standard wrenching compatibility. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. With a Strength Class 8 rating and nylon insert rated to 250°F maximum temperature, this nut meets rigorous industrial requirements for heavy-duty applications.
