ARP 12-point nut in 7/16-20 thread taking a 5/8 socket, made from 8740 chrome moly. ARP catalogues this as a bulk fastener rather than a vehicle-specific kit, so it is the nut you buy to match an existing ARP stud in rod, main, head or accessory service. The 12-point head is what lets you get a socket on it in the tight clearance a hex nut will not clear, and the parallel-ground seating face keeps the load square to the stud so the reading on your torque wrench reflects actual clamp load.

ARP publishes this part number and its 8740 chrome moly material, and nothing further, no package quantity, nut height, or tensile rating is given for it. It is a genuinely different part number from ARP 301-8314, which ARP also lists as a 8740 chrome moly nut; ARP does not publish what separates the two, so we have not guessed. If you need a specific quantity, height or grade confirmed before ordering, contact us and we will confirm it with ARP. Wrench size: 5/8 socket. Head style: 12-point. ARP part number 301-8354, ordered and stocked separately from ARP 301-8314. ARP publishes no package quantity, nut height or tensile strength for this part number.
