Torque Angle Description

TORQUE ANGLE DESCRIPTION
The process to use a torque angle meter tool is as follows. First, a specific torque is applied using a torque wrench. Next, a special angle of rotation(s) is applied using a torque angle meter tool. For example, the specification of 27 Nm (20 ft. lbs.) + 60 + 30 degrees means:

1. Use a torque wrench to tighten all bolts in sequence to 27 Nm (20 ft. lbs.).
2. Then, use a torque angle meter to turn all bolts in sequence an additional 60 degrees.
3. Finally, use a torque angle meter again to turn all bolts in sequence another 30 degrees.
Do not short-cut this sequence by tightening to specification, then turning to 90 degrees (60 degrees + 30 degrees) in one step. Tightening is done in steps for proper bolt stretching and clamping to take place
