Professional Applications & Engineering Value

This M8 nylon insert flange lock nut delivers critical vibration resistance where conventional fasteners fail. The nylon locking element creates consistent friction against bolt threads, preventing loosening from machinery vibrations, impact loads, and thermal cycling. Manufactured from zinc yellow-chromate plated steel, it provides superior corrosion protection for automotive assemblies, industrial equipment, and machinery exposed to oils, moisture, and environmental contaminants. The integrated 17.9mm flange diameter distributes clamping force effectively, reducing surface pressure and preventing damage to connected materials. With Class 10 strength rating and compliance with DIN 6926 standards, this flange lock nut ensures reliable performance in critical applications where safety and durability are paramount.

Specification Summary & Compliance

This metric M8 x 1.25mm coarse thread flange nut features Class 6H thread fit tolerance for precise engagement with mating components. The nut conforms to DIN 6926 specifications for dimensional accuracy and performance requirements. With 13mm hex width and 11mm height, it provides standard tool engagement while the 17.9mm flange diameter and 1.2mm flange thickness ensure optimal load distribution. Manufactured from plated steel with environmental compliance, this locking nut meets industry standards for heavy-duty fastening applications requiring vibration resistance and thermal stability.
