Can stainless steel screws be made with very small tolerance?

Last week, the Shi Shi Tong screw manufacturer received an email from Mike from Australia, he said that he needed 2 types of stainless steel screws, the tolerance of screws is very small, it must not be out of tolerance, otherwise, they will be unable to use. Ask if we can do it.

After looking at Mike’s drawings, the Shi Shi Tong screw manufacturer found that the tolerance requirement of the diameter of the stainless steel screws step is +0/-0.025mm, and the tolerance requirement of the step length is +0.025/-0.025mm. The tolerance required by the customer exceeds the tolerance required by the machining of the vehicle. To control the tolerance required by the customer, it is necessary to use the grinding machine to process after the machining of the vehicle, so that the cost of the customer will rise a lot.

Mike said that he also understood. However, the reserved position of their accessories was very small when they were making them, so the tolerance could not be exceeded. It must be such a size and tolerance, or they could not carry out the assembly. In addition, Mike asked us to tell him how long the production time will be if the stainless steel screws are handled in this way.

Because the machining and grinding process is more labor-intensive, and the speed of cold heading production is not as fast, the production of stainless steel screws with such a small tolerance takes about 12-20 working days.
