Product Details

ARP cylinder head nuts in chrome moly steel are replacement fasteners for engine builders and rebuilders. They are also sold as cylinder head nut kits or head stud nuts. They are made to give reliable clamping force in the cylinder head assembly.

Key Features:

  • Chrome moly steel construction: This alloy gives high strength and durability for demanding engine use.
  • Precision manufacturing: ARP makes its fasteners in the USA. Threads are typically rolled for consistent fit and good fatigue resistance.
  • Designed for head stud applications: The nuts are intended to help keep clamping load even across the cylinder head and head gasket.
  • Trusted brand: ARP is widely known for performance and racing fasteners, and for its quality control.
