ARP NUT KIT - 5/16"-24 - 12-POINT - 300-8331

ARP nuts are made from aerospace-quality material with 12-point style heads. Available in chromoly or stainless steel, they come in many sizes to meet just about all of your needs and are rated at 180,000 psi tensile strength.

ARP 300-8331 is a pack of ten 5/16"-24 thread, 12-point nuts. They are typically used for high-performance automotive and racing engine assemblies, securely holding down connecting rods, cylinder heads, and various valvetrain and driveline components where extreme clamping force and precision are required.

These nuts are prized for their heavy-duty, compact design and are built to exacting standards:

• Material Composition: Constructed from premium 8740 chrome-moly steel (often with a black oxide finish) or ARP 300-series polished stainless steel.
• Tensile Strength: Rated at 180,000 psi, offering superior rigidity and preventing stretching or failure under high heat and heavy loads.
• 12-Point Design: The double-hex head design allows the use of a standard 3/8" socket while providing a more compact profile and higher torque-wrench clearance than traditional hex nuts
