Special screws, Shi Shi Tong quality control for you

Last month, Shi Shi Tong received an order from a customer for special screws. After the customer placed the order, Shi Shi Tong would prepare the production drawings of screws and send them to the workshop.

Because the surface of the customer’s special screws needs fine carving, it is impossible to meet the customer’s requirements to produce them according to the head size of the finished products. Therefore, Shi Shi Tong enlarged the diameter of the screw head before going to the workshop, so that after finishing the head steps, the head can be made into the size the customer wants through CNC.

At the same time, the tolerance of the customer for the thread is ±0.1mm. This tolerance Shi Shi Tong can produce, but the customer’s screw also requires surface treatment, in the surface treatment, the thread is easily in the process of processing part, the size will be too small, may also cause the screw can not meet the customer’s requirements.

In order to solve this problem, Shi Shi Tong will make it go up for tolerance when rolling thread, and agreed with the people in the electroplating factory, let them try to avoid the situation of reducing the thread when dealing with, so as to control the size of the special screws in the range required by the customer.
