Serrated Flanged Hexagon Nuts (DIN 6923)

FULLERKREG DIN 6923 Serrated Flanged Hexagon Nuts combine a wide bearing flange with a serrated contact face — delivering built-in anti-loosening performance without additional washers. The integrated serrations bite into the mating surface under torque, resisting vibration-induced loosening in automotive, structural, and industrial assemblies. Available across multiple material grades and surface treatments for every application environment.
