Class 10 Steel / JIS B-1190 Serrated Flange Nuts

M8, M10X1.25, and M12X1.25 JIS flange nuts have a reduced wrench size for tight clearance applications where a small wrench is required. Commonly used in automotive and motorsport applications.

M6 JIS Flange Nuts still have the common 10mm wrench and are not considered small wrench.

The flanged form acts as a built-in washer to evenly distribute force over a larger area. Also known as hex nut with integrated washer.

Serrated Bottom Flange

The serrations on the bottom of this flange nut provide a locking action, digging into the parent material when tightened down and able to withstand extreme vibrations without loosening. Serrated flange nuts are meant to permanently mar the material they are installed against.

Material

Hardened Class 10 metric flange nuts provide a high strength, high tensile fastening solution. Commonly paired with Class 10.9 metric bolts and screws.

Finishes

Zinc Plated and Yellow Zinc Plated finishes provide corrosion resistance without sacrificing strength. Black oxide provides minimal corrosion resistance, best for dry environments.

Also known as JIS B1190-10, hex nut with integrated washer.
