Professional Applications & Engineering Value

This M4 nylon insert lock nut delivers critical vibration-proof security in machinery, automotive, and electronics assemblies where loosening under stress is a common failure point. The 18-8 stainless steel body resists corrosion from moisture, chemicals, and outdoor exposure, while the nylon insert creates consistent friction to dampen shocks and maintain clamp load. With coarse metric threading (M4 x 0.7mm) and Class 6H thread fit, it offers rapid installation with reduced cross-threading risks. Its external hex drive and compliance with DIN 985 make it a versatile, reliable choice for OEMs and maintenance teams needing durable, reusable locking solutions up to 220°F.

Specification Summary & Compliance

Manufactured to DIN 985 specifications with Class 6H thread fit and coarse metric threading (M4 x 0.7mm). Dimensions include 7mm width and 5mm height. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use in global industrial markets.
