Hexagonal K-nuts
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.
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.
