Nuts and Bolts for Engine Builds

Engine fasteners hold critical parts together under heat, vibration and repeated load. Studs and nuts clamp components such as cylinder heads, main caps and accessories, and a quality nut helps keep that clamping force consistent. Builders often replace worn or stretched hardware during a rebuild. Others upgrade to performance fasteners when they add power and want more confidence in their hardware.

We currently have 9 nuts and bolts in stock, all from ARP. Examples include the ARP 7/16 Inch -20 12pt Nut Kit and the ARP M12 x 1.25 12pt Nut Kit. A twelve-point nut has a compact outer profile, which helps when a socket has to reach into tight spaces around the engine.

  • Match the thread size and pitch to your existing studs or bolts, and confirm whether you need inch or metric hardware.
  • Count how many fasteners your job needs before choosing a kit.
  • Follow the fastener maker's torque and lubrication instructions.
  • Replace any nuts with damaged threads or rounded corners rather than reusing them.

To narrow the list, pick your vehicle to see what fits.
