Professional Applications & Engineering Value

This M14 flange nut delivers critical engineering solutions where vibration resistance and distributed load capacity are paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment, automotive assemblies, and machinery exposed to moisture or chemicals. The integrated 29.9mm flange eliminates need for separate washers while preventing surface damage and maintaining joint integrity under dynamic loads. With Class 10 strength rating and fine thread pitch, this fastener maintains clamp force in high-vibration environments like power transmission systems, heavy equipment, and structural frameworks. The external hex drive ensures compatibility with standard torque tools for efficient assembly in manufacturing and maintenance operations.

Specification Summary & Compliance

Manufactured to DIN 6923 and ISO 4161 standards with Class 6H thread fit precision. Features M14 x 1.5mm fine metric thread with right-hand direction. Dimensions include 21mm width across flats, 14mm height, 29.9mm flange diameter, and 2.1mm flange thickness. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Class 10 strength rating ensures mechanical performance for critical industrial applications.
