• Enhanced clamping force distribution with integrated flange eliminating need for separate washers
• High-strength Class 10 steel construction ensures reliable performance in demanding industrial applications
• Secure locking mechanism with serrations that bite into mating surfaces for permanent fastening
• Standard external hex drive provides familiar installation with common tools and optimal torque transmission
• Precision M5 coarse threading (0.8 mm pitch) enables quick assembly and reduced cross-threading risk
• DIN 6923 certification guarantees dimensional accuracy and consistent quality across batches

Professional Applications & Engineering Value

This Class 10 steel flange lock nut delivers exceptional engineering value in applications where vibration-induced loosening compromises safety and performance. The serrated locking design creates permanent friction against mating surfaces, making it ideal for heavy machinery, automotive assemblies, and industrial equipment subjected to constant dynamic loads. The integrated 11.8 mm flange distributes clamping force over a wider area, reducing surface pressure and preventing damage to soft materials. Manufactured to DIN 6923 standards with Class 6H thread fit, this M5 x 0.8 mm metric nut ensures precise engagement and reliable performance in critical fastening applications where maintenance access is limited.

Specification Summary & Compliance

This flange lock nut features M5 coarse thread with 0.8 mm pitch and Class 6H thread fit per ISO standards. The 8 mm external hex drive and 5 mm height provide optimal tool engagement. Manufactured in compliance with DIN 6923 specifications, this component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for various industrial applications without hazardous substance restrictions.
