M12 x 1.50 metric high tensile steel competition wheel studs from Grayston Engineering. These studs feature an M12 x 1.50 thread, with a length from the underside of the head, to the end of the thread of 51mm, but more importantly, has a splined section to press into your hubs with a 14.3mm diameter.
These studs are suitable for Gp.4 wheel hubs and various 'GM' Vauxhall models with the same thread pitch and spline diameter. So as well as Vauxhall's they are also useful to fit other vehicles, Ford included, especially where the original studs have become loose in their hubs or driveshaft holes.
Also interchangable with various Japanese models, to change from a 12 x 1.25 thread, to the coarser M12 x 1.50 thread as desired.
