12x125 60° tapered copper-plated steel nut - A.I. Tech

The A.I. Tech wheel nut with M12 × 1.25 threading features a 60° tapered seat for mounting a compatible rim. Its through-hole design allows the stud to pass through the nut.

Made of 11SMnPb37 steel, this wheel nut is suitable for rally and track use. Its copper-trimmed finish facilitates tightening and loosening on the studs, particularly at the high temperatures associated with competitive braking. It also helps protect the nut against corrosion.

It has an overall height of 25 mm, an outside diameter of 23 mm, and a 19 mm hex drive.
