Precautions For Purchasing A Wrench

1. The material of the wrench is divided into two types, namely carbon steel material and chrome vanadium steel material. The material of the wrench is generally carbon steel. The wrench is mostly made of this material. The quality is normal, not bad or bad. The other material is a wrench made of chrome vanadium steel. The wrench of this material is the best quality. It is also more expensive.

2. When selecting the Tight Wire Socket Wrench, pay attention to the symmetry of the wrench's mouth, and the laser lettering or other markings should be clearly visible.

3, the hardness of the wrench is also an important requirement for testing, the hardness of the wrench must meet the specified standards, less or a little less, not at all, and the card position of the wrench should be accurate.

4. If it is an Telescopic Wrench, the turbine of the adjustable wrench should be flexible and sensitive, and the pin of the turbine should not be loose.
