Services TORQUE CONTROL GUIDE Tightening torque and tensile load Application of the correct force (tensile load) is essential for a reliable assembly under-tightened fasteners can work loose over-tight fasteners may distort components to be connected or shear the fastener. Tensile load depends on tightening torque applied to the fastener and the friction coefficient. Tensile load (Fo) The force in Newtons (N) which maintains pressure contact between assembled components. Tightening torque (Cs) The product of a force and the leverage length at which it is applied Torque (N.m) Force (in Newtons) x length (in metres). Tightening torque table Torque values are given for 85% fastener yield strength (documentation E 25-030). 1. Friction coefficient Choose the appropriate table according to type of fasteners used (0.10 0.15 or 0.20). Example j 0.10 2. Fastener-grade The grade of a fastener denotes its quality (best is 12.9). Check the appropriate column for the fasteners used. Example fastener dia. 10 fastener grade 3. Tightening torque (Cs). Torque values are listed in Newton-meters (Nm) for each type of fastener. In the example given the fastener would be tightened to a torque of 36 Nm. sysi tjp CONVERSION TABLE The internationally accepted unit is the Newton-metre (Nm). 1.
