ARP Self-Locking Nuts
These all-metal, self-locking nuts from ARP are ideal for use practically everywhere. They are available in 6-point Jet-nuts or 12-point K-nuts. They are offset, lightweight, temperature-resistant, positive-locking, and reusable. Once they're installed, their elastic deformation creates a friction hold that will not vibrate loose.
