A torque wrench is a tool specifically used for tightening bolts and nuts. It can help us control torque during tightening process to ensure that tightening force of bolts and nuts is up to requirement. But how to choose a torque wrench? What should I pay attention to when using it? Let's present this in detail.
1. Selecting a torque wrench
1. Choose right model and specification according to usage scenario. There are many types and specifications of torque wrenches, and we need to choose appropriate model and specification according to actual use case. Generally speaking, larger torque range of torque wrench, larger applicable bolts and nuts, but higher price.
2. Choose a branded and reliable quality torque wrench. The torque wrench is a precision tool, if quality is not good, it will affect fastening effect and service life. Therefore, when we choose a torque wrench, we must choose a brand and a reliable product to ensure efficiency and safety of use.
3. Consider frequency of use and maintenance costs. If we need to use torque wrenches frequently, we need to choose products with good durability and easy maintenance to reduce maintenance costs and operating costs.
2. Precautions when using a torque wrench
1. Before use, be sure to check whether torque wrench's torque range meets requirements and whether it is damaged or loose. If a problem is found, it must be replaced or repaired in time.
2. During use, keep torque wrench in vertical direction to avoid lateral force, so as not to affect accuracy of torque.
3. During use, adjust torque value of torque wrench as necessary to ensure that tightening torque is correct. At same time, be careful not to exceed maximum torque range of torque wrench so as not to damage tool or fasteners.
4. During use, pay attention to care and maintenance of torque wrench. Clean and lubricate torque wrench regularly to increase service life and accuracy.
In short, torque wrench is a very important tool, it can help us ensure that fastening strength of fasteners meets requirements to ensure safety and stability of machinery and equipment. Therefore, when choosing and using a torque wrench, we must pay attention to above points in order to ensure efficiency of use and safety.
