Thread surface roughness
The surface roughness requirements for threads are 3.2 for qualified products and 1.6 for first class and excellent products. The accuracy of labeling on threads, such as M8X1-6h, requires a relatively high surface roughness. The requirements for con...Read More -
How to determine if the bolts are tightened Torque measurement technology
1.Why do we need to perform static torque testing? In many cases, the torque value during the production process and the torque value detected during offline testing are different. For example, the torque displayed on the controller is 100Nm, and the torque value dete...Read More -
