Lightweight self locking motorsport nuts made to aerospace specs !
Hexagonal k-nuts and anchor nuts
K-nuts are typically used to secure:
- suspension parts: upper & lower control arms, tie rods, shock assembly to the topmounts...
- brake parts: brake caliper to the caliper mount, rotor to the rotor hat, master cylinders to the pedalbox...
- other applications: turbo manifold to cylinderhead, areas with limited space, high heat areas...
The K-nuts are lightweight, self-locking and with a reduced hex. The fixed anchor nuts and floating anchor nuts are both rivet mounted. Contact us now for any enquiries, quote requests or remarks.
The K-nuts are used across the motorsport disciplines. We mostly sell them for rally cars (WRC, S2000, R3...) and circuit racing cars (touring cars, GT cars...), but they are also used in formula cars (F1, F3...), karts and racing motorcycles. Send us your enquiry and we will supply you!
We cover a complete range of metric K-nuts with coarse pitch thread as well as fine pitch thread. The most common metric sizes for K-nuts are M5, M6, M8, M10 and M12. However we also consider the sizes M3, M4, M7 and M14 as standard. 1/4"-28 UNF, 5/16"-24 UNF and 3/8"-24 UNF are the common sizes of the UNF threaded K-nuts.
K-nuts are developed by the aerospace industry. The goal was to be able to fasten the components of an airplane with a nut that is vibration proof and lighter while being more resistant to corrosion. That is why they're often called jet nuts!
