84 16 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 Strength class 12.9 Strength class A2-70 M1.6 28 20 M2 60 30 M3 210 110 M4 500 260 16.6 Specific Information on MINISCALE PLUS Information on installation and start-up of MINISCALE PLUS can be found in the download section of www.schneeberger.com .
