1. With preset torque data and sound assembly. When the tightening torque of the fastener reaches the preset data, it can automatically send a signal "click", accompanied by an obvious feeling of vibration when touching, prompting to complete things. After releasing the effective force, all relevant parts of the board can be reset automatically.
2. Two directions can be switched. Turn the ratchet steering switch and apply force to the board counterclockwise.
3. Metric and imperial (N.m, lbf.ft) double scale marks; Handle differential scale line. The reading is clear and accurate.
4. Forged from boron steel, it is durable and has a long life span. The calibration can be traced back to the National Institute of technical standards (NBS) of Western powers.
5. The accuracy conforms to ISO 6789:1992 ASME B107.14 , GGG - W-686. ± 4% 。 Usage essentials of preset torque plate
