Professional Applications & Engineering Value
This M4 locknut with distorted thread technology delivers critical vibration resistance in demanding applications where safety and reliability are paramount. The zinc-plated steel construction provides essential corrosion protection for machinery, automotive assemblies, and electrical enclosures exposed to environmental elements. Engineered with Class 8 strength and coarse metric threading, this external hex locknut maintains clamping force in high-vibration environments like motor mounts, conveyor systems, and industrial equipment. The top-lock distorted thread design creates consistent friction along the mating bolt threads, eliminating the need for additional locking devices while ensuring secure fastening in right-hand thread applications.
Specification Summary & Compliance
This metric locknut features M4 x 0.7mm coarse thread with Class 6H thread fit tolerance, ensuring precise engagement with matching bolts. Manufactured to DIN 980V standards with dimensions of 7mm width and 4.2mm height. The component is RoHS 3 (2015/863/EU) compliant and meets Class 8 strength requirements for industrial applications requiring reliable locking performance and dimensional consistency.
