The special socket set in five-piece design is supplied in a plastic box. The special socket spanner set contains plastic-coated sockets for wheel assembly in the spanner sizes 15, 17, 19, 21 and 22 mm. These sockets allow damage-free work on delicate aluminium rims. The five-piece special socket set is therefore suitable for almost all wheel bolts and wheel nuts on passenger cars, including Smart and Vauxhall Insignia.
