Torque wrench socket IBT /S series

1. This is Germany standard (DIN) above, the figure in the form is the max torque of the bolt, and the recommended torque is 80% of chart figure. 2. The recommended tightening torque equals the figure in the form*(80%-90%). For instance: M 52, strength grade is 8.8, the torque is 4704*90%=4233.6 N.m 3. It is recommended that loosening torque equals about 150% of tightening. For instance, the tightening torque is 4233.6*(1.5-2)=6350.4-8467.2 N. m
