The material of the wrench is basically made of carbon steel and chrome-vanadium steel. You can choose a material with a high grade of chrome-vanadium steel, and the quality is relatively good.
2. Tolerance range
Each nut has a model, so you need to select the corresponding wrench when you need to unscrew, and the opening of the wrench should be appropriately enlarged, so that the nut can be unscrewed quickly, which requires accurate opening or plum blossom size.
3. Torque and hardness
A high-quality wrench needs a perfect combination of hardness and toughness. As long as the two are just right, the life of the wrench will be longer.
4. Punching
The punching opening part of the wrench should be round, smooth and stable, and the inner wall of the hole should be free of burrs and knife marks, and the handshake should be round and free of burrs, otherwise it will affect the user's experience.
5. Surface treatment
There are various surface treatment methods for wrenches, among which the watermark fog treatment is the most high-end, while the matte matte treatment will have slight differences. In fact, when purchasing a wrench, you can also judge whether the surface treatment is perfect from the above specifications and the quality of the brand. , high-quality wrench trademarks and specifications are very clear, uniform font
6. Thickness
The thickness of the wrench of the same specification will be smaller and the weight will be lighter, which will make the user feel more comfortable, so the quality is also better.
7. Style
There are many styles of wrenches, and each production process is different, but you should know the usefulness of the corresponding specifications and models when purchasing, so as to prevent the use of the production from being delayed due to the wrong style selection.
The above are the details that should be paid attention to when purchasing a wrench. The specifications and standards of high-quality wrenches in all aspects will not be repeated here. Wrench manufacturers should strictly control the quality, so as to be worthy of consumers' trust. After consumers buy professional wrenches, they should also be properly maintained during use, so as not to reduce their service life.
