It is not uncommon for this type of stud to pull out of the hub, if this happens Revington TR are at the rescue with this repair procedure. This stud has the same thread type and length protruding from the hub for wheel attachment as a standard steel wheel stud 100869 (steel wheel length) but with an oversize thread into the hub. This oversize thread has been selected to be the same pitch as the original thread but a size larger. In this way no drilling out is usually necessary as the special tap RTR1379 picks up on the original thread and simply produces a similarly pitched thread but of a larger diameter.
Be sure to order the special tap RTR1379 at the same time as the studs are ordered. Also, if wire wheel adaptors are being fitted, be sure to cut the studs down once the attachment nuts have been fully tightened, leaving 1.5 threads protruding. Then trial fit the wheel with a blob of plasticine at the ends of the studs to ensure the studs do not touch the wheel at any point.
Repair studs 10mm longer are also available under part number RTR1385+10
