Professional Applications & Engineering Value

This M22x2.5 Class 10 locknut delivers critical engineering solutions for applications where vibration-induced loosening poses significant safety and performance risks. The zinc-plated steel construction provides essential corrosion resistance in demanding environments like automotive assemblies, industrial machinery, and heavy equipment. The distorted thread locking mechanism at the top section creates consistent friction and mechanical interference, effectively countering rotational forces without requiring additional locking components. This metric hex locknut maintains its integrity under high-stress conditions, making it ideal for critical joints in manufacturing equipment, transportation systems, and construction machinery where reliable vibration resistance is non-negotiable for operational safety and reduced maintenance intervals.

Specification Summary & Compliance

This metric locknut features M22x2.5 coarse threads with Class 6H thread fit tolerance for precision engagement. The external hex drive design (32mm width) accommodates standard wrenching tools, while the 22mm height provides optimal thread engagement. Manufactured to Class 10 strength standards with right-hand thread direction and top lock distorted thread configuration. Compliant with RoHS 3 (2015/863/EU) environmental regulations for industrial applications requiring verified material safety standards.
