Head Stud Hardware
Head studs clamp the cylinder head to the block and hold the head gasket in place under combustion pressure. The nuts that thread onto them do much of the work, since they are what you tighten to load each stud. Builders often fit head studs and matching hardware on boosted or high-compression engines. They also choose them when they want consistent clamping force that can be serviced without wearing the threads in the block.
We currently have 1 product in stock in this category, from ARP. It is the ARP M12x1.25 Replacement 12pt Nut, sold as one nut. It is a useful single replacement if a nut from your existing stud setup is lost or damaged.
Confirm the thread size and pitch match your studs exactly.
Use the lubricant and tightening procedure the stud maker specifies.
Replace any nut with damaged threads or rounded points rather than reusing it.
Make sure you have a socket that fits a 12-point nut and enough clearance to use it.
To see what works with your engine, pick your vehicle and we will show you what fits.
