Professional Applications & Engineering Value
This M4 nylon insert lock nut is engineered to address common industrial challenges such as vibration-induced loosening and thermal stress. The nylon locking type creates a resilient barrier that maintains clamp load under cyclic forces, ideal for machinery, automotive, and electronics where stability is critical. Made from zinc yellow-chromate plated steel, it resists corrosion in harsh environments, while the metric coarse thread with Class 6H fit ensures precise alignment and reduces cross-threading risks. Suitable for applications up to 220°F, it provides long-term reliability in assemblies exposed to temperature variations, supporting efficient maintenance and reducing downtime in industrial fastening systems.
Specification Summary & Compliance
This locknut features a M4 x 0.7mm thread with coarse spacing and Class 6H thread fit for dimensional accuracy. It complies with DIN 985 and ISO 10511 standards, ensuring consistent quality and performance. The product meets industry requirements for material and manufacturing specifications, with the zinc plating offering environmental resistance in line with common industrial practices.
