105 | M72 | 55 | 1. This page is the German industrial standards, torque values in the table for bolt reaches 70% of the yield limit determination.
2. Recommend locking torque value is: the data in the table x 80%.
For example:8.8 magnitude bolt, for example: M48, locking torque as: 400 * 80% = 320 KGM.
3. Break loose torque value for locking torque 1.5 ~ 2 times. For example: the cases of locking torque is 320 KGM, they break loose torque is about 320 x (1.5 ~ 2) = 480 ~ 640 KGM. | ||
