Professional Applications & Engineering Value

This M10 locknut is engineered to address critical challenges in vibration-prone and high-load environments. The distorted thread locking mechanism at the top creates consistent friction, effectively countering rotational forces that cause standard nuts to loosen over time. Made from zinc yellow-chromate plated steel, it resists rust and corrosion, making it suitable for outdoor equipment, automotive assemblies, and industrial machinery exposed to moisture or chemicals. With a Class 10 strength rating and metric coarse threading, it ensures dependable fastening in heavy-duty applications like engine mounts, conveyor systems, and structural frameworks, reducing maintenance downtime and enhancing operational safety. The external hex design allows for quick installation with standard tools, streamlining assembly processes in manufacturing and repair workflows.

Specification Summary & Compliance

This locknut features an M10x1.5mm coarse thread with Class 6H thread fit for precise dimensional accuracy per ISO metric standards. It complies with industry specifications for distorted thread locknuts, including strength requirements for Class 10 ratings. The zinc yellow-chromate plating meets RoHS and REACH environmental directives, ensuring safe use in various sectors. Dimensions include a width of 17 mm and height of 10 mm, designed for consistent performance in automotive, aerospace, and general industrial applications under ASME and related fastening guidelines.
