Is the tolerance of stainless steel screw ±0.1mm ok?

There will be no identical leaves or snowflakes. And stainless steel screw is the same, is not exactly the same.

With the knowledge of the fastener industry, is stainless steel screw at the time of production, because the magnitude of the impact time molding, mould, etc. There may be a little different, so at the time of molding will lead to the size of the screw is not the same, the longer, the short, however, so the screw would need tolerance in production.

But the tolerance of stainless steel screw is very small, only ±0.1mm is ok? For the cold heading process, the tolerance is only ±0.1mm is very difficult to control, so technicians need to be very careful in debugging the machine. Of course, you can also take the screws to the multi-station machine for better control. However, the tolerance of cold heading still depends on the specific size of the screw, if the larger the size, the more difficult to control the tolerance.

If the turning process is used to produce stainless steel screw, then this tolerance can be achieved, because the general turning tolerance can be controlled at ±0.05mm.
