Web30 oct. 2024 · The torque expressed in newton-meter [N.m] is the product of force and radius (the lever arm). A common mistake is to confuse newton-meter [N.m] and newton per meter [N/m]. Of course, the greater is the radius, the higher is the torque for a given force. The torques are expressed in N.m. The conversion can be done thanks to the following … WebTorque figures for bolts and screws with metric thread and head dimensions, as in DIN 912, 931, 934 etc. The figures MA in this table include: a)coefficient of friction microns total + … WebThis table shows the maximum permissible tightening torques and the resulting maximum preload for A1, A2 and A4 stainless steel fasteners.
