(22) M6 Serrated Flange Nuts

Studs are 14.9 Thermal Black Alloy Steel
  • High-strength 14.9 studs are fatigue resistance under repeated stress
  • Heat treated to increase the strength, hardness, and toughness of the material.
  • Thermal black coating provides a layer of protection against chemical corrosion.
  • Quicker installation and easier maintenance offering a more professional look. 
Serrated Flange Nuts 
Used in automotive applications, flange nuts feature an integrated washer-like
surface, distributing pressure evenly, providing a balanced clamping load. Serrations
on a flange nut are angled to keep the nut from rotating in the direction that would
loosen the nut.
