Engine hardware nuts thread onto studs to hold engine parts together under heat, vibration and clamping load. Builders often replace worn or stretched nuts during a rebuild or when fitting new studs, so that every fastener clamps evenly and holds its torque.
We currently have 2 products in stock in this category, both from ARP. They are the ARP 7/16 inch-20 Hex Nut Kit and the ARP 7/16-20 Hex Nut Kit. This is a small, focused selection, so check the details of each kit against your build before you order.
A few things to keep in mind when choosing nuts:
Match the thread size and pitch to the studs they will go on.
Check the hex style and wrench clearance around the part.
Follow the lubricant and torque guidance from the fastener maker.
Replace nuts as a set so clamping stays consistent.
To narrow things down, pick your vehicle to see what fits.
