Professional Applications & Engineering Value

This Class 8 steel flange nut delivers exceptional engineering value through its robust metric hex design and integrated flange. The 21.8mm flange diameter significantly increases bearing surface area, effectively distributing clamping force and preventing material deformation in assembled components. Manufactured from high-grade steel and featuring M10 coarse threading with 1.5mm pitch, this DIN 6923 compliant nut resists loosening under vibration in heavy machinery, automotive assemblies, and structural frameworks. The external hex drive enables efficient torque application with standard wrenches, while the Class 6H thread fit ensures precise mating with corresponding bolts for leak-proof and secure connections in demanding industrial environments.

Specification Summary & Compliance

This flange nut maintains precise dimensional tolerances per DIN 6923 standards, featuring M10 x 1.5mm coarse metric thread with Class 6H thread fit for optimal engagement. The external hex drive measures 15mm across flats with 10mm height, while the integrated flange provides 21.8mm diameter with 1.5mm thickness. Manufactured from Class 8 strength steel, this component is RoHS 3 (2015/863/EU) compliant for environmental safety in industrial applications.
