We have a good understanding of the correct use of the screw on the method. If we have a screw on our hands, then we can go to understand the characteristics of the screw, you can understand the above raw materials, you can in the specifications, hardness above to understand, we only have a comprehensive understanding of the characteristics of this screw, we To be able to correctly use this screw, otherwise, we will never play a small screw the biggest role.

Q:Screw hole slip wire how to do?

Can be in the original screw hole at the larger screw hole to cover the original screw hole, the most good new hole diameter is greater than the original hole diameter; 2. If the original thread hole has no space, then just change to other places to re- drilling

Q:How is the screw produced

There are three types of technology: cold heading, red, turning; rolling teeth generally have four kinds of technology: rubbing teeth, rolling wire, teeth, car teeth; but our screw industry is the most common Is the beginning of the cold heading, the machine rubbing teeth, so that large output, low cost

Q:What is the principle of screw

How it works: Lever principle The screw itself is no theory, the screw thread is a long slope, but the angle is very small. You can assume that when you twist the thread, it is equivalent to pushing a square on the slope. Force analysis: box weight + friction and thrust from now on the use of the principle of leverage.
