In order to better fix and avoid falling and loosening, it is generally necessary to screw the bolts to a certain depth, so what is the standard for the screwing depth?

A.What is the screw depth standard?
The screw-in depth standard should generally be between 1.5 and 1.6 times the outer diameter of the screw thread. When we screw the screw, generally the depth of the screw should be controlled between 1.5 times and 1.6 times the outer diameter of the screw thread, but in actual operation, the specific screwing depth of the screw is generally calculated based on 1.5 times , and a little margin is required.
The screw-in depth is not fixed. How much to screw in depends on the shape and specification of the screw. In actual operation, we can also calculate the screw-in depth according to the screw diameter plus radius.

B.What aspects should be paid attention to when tightening screws
1.In the process of screwing, it is best not to screw all the screws in at one time. You should screw in one-third of the screws first, and then screw in one-third of the screws at the diagonal position, so that the items can be Keep the balance, and then according to the same method, screw the screws in other positions into one-third. When all the screws are screwed in one-third, you can use a screwdriver to screw in the remaining two-thirds of all the screws Go in and let the screw be tightened.

2.In the process of screwing, you must be careful and pay attention to your own safety. The force of screwing should not be too large or too small. If the user is using an electric screwdriver to screw in the screw, the two should be aligned, and the electric screwdriver needs to be tightly attached to the screw head
