Grayston - Thread: M12x1.5 / length: 51 mm / spline: 14.3

Grayston metric competition wheel studs, with an M12 x 1.50 thread in the 51mm length, with a 14.3mm splined section. These longer studs were devised to suit the larger spline size on many Vauxhall models, but also popular with many Japanese car owners. They are also often used on Fords where the spline in the hubs or half shafts is worn, and the studs are loose. In this case, you drill or ream out the holes to suit these larger splined studs.

Spline Diameter: 14.3mm

Thread Size: M12 x 1.50

Stud Length: 51mm

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