THERMOSTAT HOUSING STUD – 5/16″ – 50MM

Probably the most changed stud on the mini. This is the length used on every A series engine until the introduction of the sandwich plate when longer ones were required. A stainless steel variety C-STR286 is available which we do recommend if you intend on keeping your car as it will save lots of hassle in the future as the standard ones always corrode. 5/16″unc and unf at nut end, this stud is 1.9375″long. This stud originally replaced CHS2514 but is 2-3 threads(5mm) longer on the end the nut fits which means it might have to be shortened for use on manifolds for fitting carbs so CHS2514 is advised. Also used on inlet manifold for HIF carb and the block for mechanical fuel pump mounting.
