Professional Applications & Engineering Value

This M10 locknut with distorted thread technology addresses critical vibration-induced loosening in industrial machinery, automotive assemblies, and heavy equipment. The black phosphate steel construction provides superior corrosion resistance while maintaining the Class 10 strength rating required for high-stress applications. The metric coarse thread (1.5mm pitch) ensures rapid installation and reliable performance in environments where thermal cycling and dynamic loads compromise standard fasteners. Engineered for permanent fastening solutions, this external hex locknut delivers consistent locking performance without requiring additional locking elements, reducing assembly time and maintenance costs across manufacturing, construction, and transportation sectors.

Specification Summary & Compliance

This locknut features M10×1.5mm metric coarse threads with Class 6H thread fit tolerance for precision engagement. The distorted top-lock thread design ensures vibration resistance while maintaining standard installation characteristics. Manufactured from black phosphate steel with Class 10 strength rating, the nut complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards. Dimensions include 17mm width across flats and 10mm height, conforming to standard metric hex nut profiles for universal tool compatibility.
