K-nut
M8 x 1mm
Spanner size 10mm
K-nuts are the most applied locking nuts in motorsports applications.
Originally designed for the aerospace industries,
they were found to be ideal for use in a lot of motorsport applications
because of the high strength, low weight and better temperature resistance.
They have a reduced hex, so a smaller spanner size is used.
This is ideal for compact and functional design and eliminates the need for excessive material in casings.
K-nuts can be used up to 235 °C or 450 °F
