Torque angle meters, or torque angle gauges, are designed to ensure that the "tightness" among fasteners on a given component is equal. Torque angle meters are calibrated in degrees instead of foot-pounds of torque. Tightening by angle of degrees rather than torque pounds per foot removes any error produced by friction in the threads of the fasteners. It's easy to learn to use a torque angle meter by following a few simple procedures.
Things You'll Need
- Fastener (nut or bolt to be tightened)
- Torque wrench
- Torque angle meter
Check the specifications of the fastener to be tightened to determine the correct torque value to be used for your specific application. The value will normally be quoted in foot pounds. Then check to see what the correct torque angle specifications are for that fastener (if given). Incorrect torque application may damage the device you are working on.
Tighten the fastener to the approximate specified torque value using a standard torque wrench. Install the torque angle meter over the head of the fastener, and place the standard torque wrench onto the top of the torque angle meter.
Turn the standard torque wrench the specified number of degrees that were specified for that fastener. The torque angle meter will tell you this. Watch the torque meter closely for the correct amount of degrees to be applied. Stop torquing when this value is attained. If other fasteners are required for your application, make sure to tighten them all as closely as possible to the same torque value and torque angle.
