Set of three studs and three 12-point nuts and washers. Never again will the aluminum thermostat housing seize to a rusty stud if you use these high-spec stainless studs and 12-point nuts from ARP. For A-Plus housings with a sandwich plate underneath, see SEN0087B.
If you don't need the high-tensile spec of the ARP product, we also offer an aftermarket kit (SEN0087E).
