Original BMW Hex Head Screw ST 4.8 x 18 for BMW 3, 5, 6, and 7 Series, X1, X3, X5, Z3, and Z4 (1995–2018)

This Original BMW hex head screw is an ST 4.8 x 18 mm tapping screw with an 8 mm hex head, used across BMW 3, 5, 6, and 7 Series, X1, X3, X5, Z3, and Z4 models from 1995–2018. The ST in BMW's size code marks a tapping-screw thread, which cuts its own mating thread in sheet metal or a plastic boss instead of turning into a tapped hole or a nut. BMW gives a weight of 5 g (0.18 oz) per screw, and production of this number began in October 2003. It supersedes 07-14-8-204-807, and BMW rates the change as exchangeable retrospectively, so the newer screw also goes into cars built before 2003. Made in Indonesia and sold individually.

Original BMW Parts carry a 24-month parts warranty.

Because one screw appears on so many chassis, the part number matters more than where it sits on a given car. BMW's parts data places it on E46, E90, E91, E92, and E93 3 Series, E39, E60, and E61 5 Series, E63 and E64 6 Series, E38, E65, E66, and E67 7 Series, E84 X1, F25 X3, E53, E70, F15, and F85 X5, plus Z3 and E85, E86, and E89 Z4 cars. If your parts diagram still calls for 07-14-8-204-807, this number replaces it directly. Count how many your repair needs before ordering, since each screw is sold on its own.
