The RAD® production program also covers mini-locks for wheel caps, socket converters as well as knurled wheel studs.
The converters will assist you if the bolt head of your lug-ware doesn't match the wheel spanner of your car.
Knurled wheel studs are safety items and as such are available to specialized workshops only.
A radius gauge is available by part # 4542. Besides others, the most common radiuses found in wheel seats (R12, R13 and R14) are provided and will help you determine the right ball seat diameter in the wheel and/or the fasteners..
