UNITS OF MEASURE

IMPERIAL                                                                   METRIC
Dimensions = inches                                             Dimensions = millimeters
Load = pounds force                                              Load = Newton
Torque = foot-pounds                                          Torque = Newton-meters
Temperature = °F                                                    Temperature = °C
 

TORQUE CALCULATION

The widely accepted formula is as follows,
 
T = K*F*D
 
where,
 
K = Estimated nut friction factor
T = Bolt torque
D = Nominal bolt diameter
