Professional Applications & Engineering Value

This M8 nylon insert flange lock nut delivers exceptional engineering value by solving critical vibration-induced loosening problems in industrial equipment and machinery. The combination of zinc-plated steel construction and DIN 6926 compliance ensures reliable performance in automotive assemblies, manufacturing equipment, and structural applications where constant motion and stress threaten fastener integrity. The integrated flange design eliminates the need for separate washers while providing superior load distribution, making it ideal for space-constrained applications. With coarse metric threads (M8x1.25) and external hex drive, installation efficiency is maximized while maintaining the high-temperature vibration resistance required for industrial environments up to 250°F.

Specification Summary & Compliance

This flange lock nut features precision M8 x 1.25mm coarse threads with Class 6H thread fit according to DIN 6926 manufacturing standards. The component maintains dimensional accuracy with 13mm width, 11.1mm height, and 17.9mm flange diameter. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards ensures safe usage across various industrial sectors, while the Class 8 strength rating guarantees mechanical reliability in demanding applications.
