BMW Tightening Torques

The maximum tightening torques are:

Only applicable to shaft screws with metric standard and fine threads acc. to DIN 13, sheet 13 and nuts with height of 0,8 x d acc. to DIN 934 and only for a m total = 0.125 (screws phosphatized, screws untreated or galvanized. Lubrication condition: unlubricated and also oiled).

For cadmium-plated screws or nuts (m total = 0.08 to 0.09) the tightening torque with screw material at the same level of utilization ca. must be 30% less than

shown in the table.

The values specified in this table apply to all screw connections conforming to the aforementioned conditions.

Not applicable when using a different surface or lubricant condition on the thread, or if the height of the nut differs.

Not applicable to necked-down bolts, self-tapping screw connections or to connections between parts made of different materials.

Important!

Maintaining specified tightening torques is vital for performing repair work to a professional standard. This presupposes that the torque wrenches required for this

are subjected to a regular inspection. Approved torque testing equipment is listed in the catalogue of workshop equipment planning documents.
