Professional Applications & Engineering Value

This M22x1.5mm nylon insert lock nut is engineered to address critical challenges in machinery, automotive, and heavy equipment sectors where vibration-induced loosening can lead to operational failures. The zinc-plated steel construction provides excellent corrosion resistance, while the nylon insert creates consistent friction to resist rotational forces. With a fine thread spacing of 1.5mm pitch and Class 6H thread fit, it ensures precise alignment and secure fastening in high-vibration environments. The 220°F temperature resistance makes it suitable for engines, motors, and industrial equipment exposed to thermal cycling, delivering reliable performance where standard nuts would fail.

Specification Summary & Compliance

This lock nut features M22x1.5mm metric fine threads with Class 6H thread fit tolerance, ensuring precise engagement. Manufactured to ISO 10511 and DIN 985 specifications, it maintains dimensional accuracy with 32mm width and 22mm height. The product carries Class 8 strength rating and is fully RoHS 3 (2015/863/EU) compliant, meeting international environmental and safety standards for industrial use.
