Shoulder screw manufacturers – strict control precision to meet customer requirements

Some time ago, Shi Shi Tong 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 drawings of the customer, the manufacturer of Shi Shi Tong shoulder screws found that the diameter tolerance requirement of the customer shoulder part was very small, the tolerance requirement was ±0.02mm. General CNC screw tolerance is ±0.05mm, this tolerance is very small. In order to achieve the tolerance of the customer, it is necessary to apply the grinder and control the tolerance manually, so that the labor cost will increase.

Therefore, the Shi Shi Tong shoulder screw manufacturers asked the customer why the tolerance should be controlled so strictly. If tolerance can reach ±0.05mm, it will save a sum of costs. The customer said that his shoulder screws were used in a precision instrument, and if the tolerance exceeded, they could not be assembled.

When producing this kind of shoulder screw for the customer, Shi Shi Tong is very careful. After the completion, there is also special QC personnel to measure the size of the shoulder part of the customer one by one to ensure that the tolerance is within the scope of the customer’s drawing so that the customer can assemble it when assembling.

When the customer received the shoulder screw and assembled it, he was very happy to tell the Shi Shi Tong shoulder screw manufacturers in the email that he appreciated our efforts and they cooperated well in the assembly.
