What is the difference between a ratchet wrench and a torque wrench?

1. Ratchet wrench is a manual screw tightening tool, single head, double head and multi-specification movable handle ratchet torx wrench (fixed hole). It is connected by the main plum blossom sleeve and the slave plum blossom sleeve of different specifications and sizes through the engagement of the female key and the male key of the hinge key. Since a plum blossom sleeve has two specifications of plum blossom through holes, it can be used for the tightening of two specifications of screws, thereby expanding the scope of use and saving raw materials and labor costs. The adjustable trigger can easily adjust the angle of use of the wrench. This type of wrench is used for tightening the screw, and has the characteristics of strong applicability, convenient use and low cost.

2. Torque wrench - also called torque wrench or torque wrench, torque is the product of force and distance. When tightening threaded fasteners such as screws, bolts, nuts, etc., it is necessary to control the amount of torque applied, so that the threads are tightened without excessive torque. Great damage to the thread, so use a torque wrench to operate. Set an upper limit of the required torque value. When the applied torque reaches the set value, the wrench will make a "click" sound or the connection of the wrench will be bent a little, which means that it has been tightened and no more force is required.

3. The difference between them is that the torque of the torque wrench can be set.
