The difference between ratchet wrench and torque wrench
abstract：Although both ratchet wrenches and torque wrenches are tools used to tighten or loosen screws and nuts, they have significant differences in function, structure and application scenarios.
Ratchet wrench for quick twisting, torque wrench for precise torque control
Although both ratchet wrenches and torque wrenches are tools used to tighten or loosen screws and nuts, they have significant differences in function, structure and application scenarios. Here are the main differences:
1. Function difference
ratchet wrench : mainly used to quickly twist screw and nut, suitable for high efficiency but no precise control of torque scene. It is continuously tightened or loosened through the ratchet pawl mechanism, without frequent adjustment of the card position.
torque wrench : Used to accurately control the torque for tightening bolts to ensure that the threads are tight and not damaged due to excessive torque. It is usually equipped with a pointer, dial or display dial, which can set and measure the torque value, and issue a prompt when the set value is reached.
2. structural differences
ratchet wrench : composed of handle, wrench head, ratchet, gear group, lock and other parts, the design pays attention to flexibility and fast operation.
torque wrench : composed of a handle, torque adjustment knob, scale, torque limiter and other parts, the structure is more complex to achieve accurate torque control.
3. Applicable scenario
ratchet wrench : suitable for occasions where bolts need to be quickly turned and torque requirements are not high, such as daily maintenance or simple assembly.
torque wrench : suitable for occasions where precise control of torque is required, such as automobile maintenance, mechanical assembly, etc., to ensure the accuracy and safety of bolt fastening.
4. Usage
ratchet wrench : through the reciprocating swing handle to achieve quick rotation, the adjustable lever can be adjusted to meet different operation requirements.
torque wrench : need to set the torque value in advance, when the operation reaches the set value, it will issue a prompt (such as "tower" sound or pointer indication) to remind the user to stop the force.
5. Choice suggestion
Choose a ratchet wrench if the bolt needs to be screwed quickly and torque is not strictly required.
If you need precise control of the torque value, choose a torque wrench, and take care to choose the right model and brand to ensure the use of effective.
Through the above comparison, you can better understand the difference between the two, and choose the right tool according to the actual needs.
