shoulder screw manufacturers strict control of precision to meet customer requirements

Some time ago, Shi Shi Tong’s shoulder screw manufacturers received an email from an American customer. The customer said he needed a shoulder screw and asked if we could produce it.

After opening the customer’s drawing, the world-shoulder screw manufacturer found that the diameter tolerance of the customer’s shoulder part is very small, and the tolerance is ±0.02mm. The tolerance of general CNC car screws is ±0.05mm, this tolerance is already very small. To reach the customer’s tolerance, it is necessary to go to the grinding machine and manually control the tolerance, so the labor cost will increase.

Therefore, Shi Shi Tong shoulder screw manufacturers asked customers why the tolerance should be so strict. If the tolerance can reach ±0.05mm, it will save a sum of money. The customer said that his shoulder screw is used on a precision instrument, and if the tolerance is exceeded, it cannot be assembled.

When producing this shoulder screw for the customer, Shi Shi Tong is very careful. After the completion, there are special QC personnel to measure the size of the customer’s shoulder part one by one to ensure that the tolerance is within the scope of the customer’s drawing. Allow customers to assemble when they are assembled.

When the customer received the shoulder screw and assembled it, he was very happy to tell the Shi Shi Tong shoulder screw manufacturers that he was very grateful for our hard work. They cooperated well during the assembly.
