Grayston - Thread: M12x1.5 / length: 63 mm / spline: 14.3

Grayston metric competition wheel studs, with an M12 x 1.50 thread, with a 63mm length and a 14.3mm splined section. These longer studs were devised to suit the larger spline size on many Vauxhall models, but are also popular among many Japanese car owners. They are also frequently used on Fords where the splines in the hubs or half shafts are worn, causing the studs to become loose. In such cases, you can drill or ream out the holes to accommodate these larger splined studs.

Spline Diameter: 14.3mm

Thread Size: M12 x 1.50

Stud Length: 63mm

Please note: the length of stud is measured from the head or washer face to the end of the thread.
