Product Details

ARP 300-8375 12-point cylinder head fastener nuts deliver professional-grade clamping force for high-performance engine builds. Manufactured from premium 8740 chrome moly steel, these precision-machined nuts are rated at 180,000 psi tensile strength for exceptional durability under extreme loads.

Key Features:

  • 8740 chrome moly steel construction with black oxide finish
  • 12-point design for precise torque application and easy installation
  • 0.600-inch flange diameter for optimal load distribution
  • Thick wall construction provides maximum strength and rigidity
  • 180,000 psi tensile strength rating exceeds OEM specifications
  • Single piece design ensures consistent performance

Engineered to ARP's exacting quality standards, these cylinder head nuts are ideal for racing applications, forced induction setups, and high-compression builds where reliable head gasket sealing is critical. The 12-point configuration allows for finer torque adjustments compared to standard hex nuts, while the black oxide finish provides corrosion resistance and a professional appearance.

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

Easy checkout. Easily found the part.

best price online. fast shipping and wright part. I recommend this site to anyone!

Happy with the purchase! The lowest price and fast shipment.

Had what I wanted at a very competitive price. Speed of which it was sent out for delivery was exellent.

I ordered a water pump from them and that Amazon was advertising as a Chrome pump. When I discovered it was not chrome, I asked to cancel the order which was prior to shipping notification. I was told by customer service it had already been sent and I would have to wait until the item was sent for a return to be processed. The return was sent back and all money was credited to my account as promised.
