Professional Applications & Engineering Value

This M8 nylon insert lock nut delivers critical vibration resistance where machinery and equipment face constant motion stress. The 18-8 stainless steel construction provides excellent corrosion resistance, making it ideal for outdoor equipment, marine applications, and chemical processing environments where moisture and corrosive elements are present. The coarse metric threading (1.25 mm pitch) ensures quick assembly while the nylon insert creates consistent locking force without damaging mating threads. Engineered to DIN 985 standards, this external hex locknut maintains reliability in automotive assemblies, industrial machinery, and electrical enclosures where vibration-induced loosening could cause equipment failure or safety hazards.

Specification Summary & Compliance

This lock nut features M8 x 1.25 mm coarse threading with Class 6H thread fit per metric standards, ensuring precise dimensional accuracy. The component measures 13mm across flats with 8mm height, conforming to DIN 985 specifications for dimensional and performance requirements. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives, confirming the absence of restricted hazardous substances. The nylon insert maintains locking effectiveness up to the maximum temperature rating of 220°F while providing reliable vibration resistance throughout the nut's service life.
