Professional Applications & Engineering Value

This M16x2mm nylon insert lock nut delivers exceptional engineering value in applications where vibration-induced loosening poses significant reliability concerns. The 18-8 stainless steel construction provides inherent corrosion resistance, making it ideal for outdoor equipment, marine applications, and chemical processing environments where moisture and corrosive elements are present. The nylon insert locking mechanism creates consistent friction against the mating bolt threads, effectively damping vibrations in machinery, automotive assemblies, and structural frameworks. With its metric coarse threading and external hex drive, this fastener offers quick installation while maintaining the security required for heavy-duty industrial applications. The combination of DIN 985 compliance and Class 6H thread fit ensures precise dimensional accuracy and reliable performance in critical assemblies where fastener failure is not an option.

Specification Summary & Compliance

This lock nut features M16x2mm metric coarse threads with Class 6H thread fit tolerance, ensuring precise engagement with compatible fasteners. Manufactured to DIN 985 standards with standard hex profile (24mm width, 16mm height) and right-hand thread direction. The product is fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, containing no restricted substances. The nylon insert maintains locking performance up to the maximum temperature rating of 220°F, providing reliable service across most industrial temperature ranges.
