ARP Metric Cylinder Head Nut

ARP Metric Cylinder Head Nuts are high-strength cylinder head nuts (also called head stud nuts) made for engines that use metric-threaded head studs. They are a dependable choice for performance, racing, and heavy-duty builds. They help keep clamping load consistent between the cylinder head and block.

Key Features:

• Precision manufacturing: ARP makes its fasteners in the USA to tight quality standards.
• High-strength construction: The nuts are built to handle the high clamping loads and heat cycles of demanding engine applications.
• Metric thread design: They are made for metric head stud and fastener applications.
• Consistent clamp load: Quality threads and bearing surfaces help give accurate torque readings and even gasket sealing.
• Engine-building quality: ARP is widely trusted by professional engine builders and racers.

These nuts suit rebuilds, performance upgrades, and race engines that need more reliable head fastening than standard hardware offers. Select the child item that matches your required thread and nut specification.
