Nuts and Fasteners for Engine Builds
Nuts and fasteners hold critical engine parts together and keep them clamped under heat, vibration and load. A quality fastener holds its clamping force more consistently, which helps keep joints sealed and parts in place. Builders often upgrade fasteners during a rebuild or when adding power, since the original hardware may not suit the job anymore.
We currently have 16 products in stock in this category, all from ARP. The range includes 12-point nut kits in both fractional and metric threads, such as the ARP 9/16in -18 12pt Nut Kit (Pack of 10) and the ARP M12 X 1.25 12pt Nut Kit (Pack of 10). A 12-point head gives you more socket angles to work with, which helps in tight spaces around the engine.
Match the thread size and pitch to the studs or bolts you are using.
Confirm whether your application uses fractional or metric threads.
Count how many fasteners the job needs and buy enough kits to cover it.
Follow the fastener maker's torque and lubricant instructions when tightening.
To narrow the list to parts that suit your build, pick your vehicle to see what fits.
