Use a torque angle gauge by tightening a fastener to the recommended torque value, place the gauge on the fastener, and tighten it to the recommended angle with the torque wrench. Use the torque angle gauge with a torque wrench to tighten all fasteners on a component.
- Check the fastener specifications
Check the fastener's manufacturer specifications for its required torque and torque angle values. The torque value is given in either foot pounds or Newton meters, and the torque angle value is in degrees.
- Tighten the fastener
Place the torque wrench on the head of the fastener, and turn the wrench until the readout indicates the required torque. Support the head of the torque wrench while tightening the fastener.
- Attach the torque angle gauge
Place the torque angle gauge on the head of the bolt, and put the torque wrench on top of the angle gauge. Start tightening the fastener, and stop once the recommended number of degrees is reached.
- Tighten the remaining fasteners
Use the same torque wrench and torque angle gauge method for the remaining fasteners. If possible, tighten the fasteners in an alternating pattern rather than a straight line. While tightening the other fasteners, always refer to the recommended number of degrees as the final measurement, because the actual torque on an individual fastener may vary due to friction.
