1. The design of the arm needs to be reasonable
The reason why a wrench can shake a tightly engaged thread is that it uses the principle of leverage. Too long a force arm not only wastes the material of the wrench, but also increases the cost. If the force arm is too short, the user will have a lot of trouble when twisting the nut. Therefore, when the power arm is planned properly, users can more easily complete tasks such as mechanical maintenance, without requiring much effort. This can be seen in the clarification of the popular wrench.
2. The raw materials for wrench manufacturing are important
The raw material for making a wrench is also one of the factors for choosing a wrench. If the raw material for making the wrench is softer than the material of the nut, it may deform or wear the wrench; if the raw material is too good, it will cost more money to buy, and may even wear nuts on the machine. Therefore, only considering the type of the force application target (ie, the nut) can a good quality wrench be purchased.
3. Choose the right wrench
Only the right wrench can help the user to work better. And "fit" means more than just the type of wrench,
Also includes the appropriate size. Wrench types include dead-end wrenches, plum wrenches, hook wrenches, etc., and their sizes include metric, imperial, etc. There are also some types of wrenches that can be changed by themselves. Users should make purchases according to their actual needs, or consult the seller before buying to avoid the trouble of subsequent returns due to the purchase of an unsuitable wrench.
