How important the thread for hub screw

Time: 2018-07-30

The accuracy thread of nuts/bolts is crucial
Many factories like to debase quality in this part, such as increase the thread hole of wheel nut, change the bolt with thin thread diameter. They do this because they can save the material and make thread easily. But, the disadvantage is that it will affect match fastness of the thread.
To judge the accuracy of thread, firstly need to check the sharpness of thread, the sharper the better.
