Installation and Adjustment Guidelines for MINIRAIL and MINISCALE PLUS
16.5 Tightening Torques for the Fastening Screws
The recommended torque values can be found in the table. These values apply to
oiled screws with a coefficient of friction of 0.12.
The coefficient of friction can be as low as 0.07 for lubricated screws. The
corresponding torque values shouldbe reduced by half.
The following table shows the torque values for the fastening screws of strength
class 12.9 (friction coefficient 0.125) and of the strength class A2-70 (friction
coefficient 0.2) in accordance with DIN 912:
Thread size
Maximum tightening torque in Ncm

M1.6 28 20
M2 60 30
M3 210 110
M4 500 260
