Brief introduction of SGTG type preset crescent torque wrench:
Crescent torque wrenches have preset torque values ​​and signaling devices. When the tightening torque of the fastener reaches the preset value, it can automatically emit a "click" signal, accompanied by obvious hand vibration. After the SGTG pre-set crescent torque wrench is released, the related parts of the wrench are automatically reset.
SGTG type preset crescent torque wrench features:
1. Made of chrome-plated alloy steel with good strength and large torque range;
2. With two-way ratchet head, small scale torque scale with differential device;
3. Can be equipped with opening head, movable opening head, hook head, pipe wrench head;
4. With preset torque value and signaling device, accuracy ± 4%;
Usage of SGTG type preset crescent torque wrench
1) The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it may slip off and damage the hexagon of the screw. For the selection principle, socket wrenches are generally preferred, followed by torx wrenches, open wrenches again, and then adjustable wrenches.
2) In order to prevent damage and slippage of the wrench, the pulling force should be applied to the thicker side of the opening. This should be paid special attention to the adjustable wrench with large force to prevent the opening from appearing in an "eight" shape and damaging the nut and wrench.
3) Torque wrenches are designed according to the strength of human hands. When encountering tight thread parts, you cannot use a hammer to hit the wrench; except for socket wrenches, other wrenches cannot be equipped with afterburning rods to prevent damage to the wrench or threads Connector.
4) When using a torque wrench, when you hear a "pop", it is very appropriate to understand the principles of various torque wrenches and the role of each part is not enough. A qualified technical operator also needs to know all kinds of torque The use of the wrench will reasonably select the appropriate measuring tool.
