WHAT ARE TORQUE MEASURING TOOLS USED FOR?
- Torque Measuring Tools are generally used in Research and Development, Inspection and Quality Control where there is a need to check torque settings
- Torque Measuring Equipment can also be used in a Servicing or Production Environment to apply torque
WHAT TYPES OF TOOLS ARE THERE FOR MEASURING TORQUE?
- Torque Measuring Tools have a dial or digital readout. They can be a Torque Screwdriver or Digital/Dial Measuring Torque Wrench design. They enable the operator to read directly from the dial or readout as the Torque is applied
- The torque can be measured as it is applied (Track mode) or the maximum torque value can be recorded (Peak mode)
WHAT ARE THE THREE TYPES OF QUALITY AUDITING TEST THAT UTILISE TORQUE
- The first of the three tests is Measurement. The measurement test is used to verify the torque value of a previously tightened fastener. This is done by making a clear mark on the surface of the nut, bolt or screw and continued onto the surface being clamped. This acts as a reference point. The fastener may then be untightened and then retightened until the marks are again in line. The torque value can then be read from the Torque Tool display.
- The second of the tests is the Just Move Test. Again this test is used to determine the torque setting of a previously tightened fastener. Using a torque measuring tool, a tightening torque is applied to the fastener until movement is just seen or felt. This torque is deemed to be a good indication of the original torque applied to the fastener.
- The third and last test is the Break Loose Test. The break loose test is another method of checking the torque applied to a previously tightened fastener. Torque is applied in the direction that loosens the fastener, at the point the fastener breaks loose, the torque is recorded. This value is an indication of the torque at which the fastener was originally tightened and is typically 20-30% lower than the tightening torque.
