Hexagonal 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.No compromise on quality. Only true aerospace products made in Europe & USA.

These K-nuts can be used up to 235 °C or 450 °F. They are made with metric threads and imperial threads. For some items the J thread form is used, which is common in aerospace applications.
