Écrou freiné Racing M8 x 1,25 clé de serrage 10

Standard hexagonal K-nuts (235°C)

Locking nut = result of elliptical deformation.
Less material = reduced spanner size.
This results in huge weight saving.
Large flange to reduce the tension by distributing the force over a larger surface.

The hexagonal M8 x 1.25 k-nut is an elliptical deformed self locking nut typically used in motorsports and aerospace applications.
