Danger:
Keep in mind that the torque values given in the chapters “Recommended Torque Settings” and “Recom-
mended Torque Settings for Disc Brakes and Hydraulic Rim Brakes” override any other torque values.
Caution:
Be sure to use stainless steel bolts only for mounting mudguards and accessory parts.
Maximum Torque Settings of Standard Bolts
Limit values of the torque settings in newton metres (Nm) for setscrews with metric threads and head contact
in accordance with DIN 912, 931, 934. The bolts are greased (friction coefficient = 0.125):
Dimension
Bolt quality (imprinted on the head)
8.8 10.2 12.9
M4 2.7 3.8 4.6
M5 5.5 8 9.5
M6 9.5 13 16
M8 23 32 39
M10 46 64 77

Observe the minimum screw-in depth. In the case of solid (hard) aluminium alloys this depth is at least 1.4 fold
the bolt diameter. In general, the weak point is not the bolt, but the component!
