Step 1: The manufacturer needs to design the specification size, head shape and groove shape of the Non-standard Precision shaft and screw specification screws according to the products you provide, and determine the material and surface treatment of the non-standard screws according to the product and its use environment.

Step 2: Provide customized drawings of Non-standard Precision nut, and clearly indicate the specifications and requirements of each part of the non-standard bolts on the drawings. If we can't provide drawings, as long as we can provide products for non-standard screws and add your requirements, we can also design products according to your actual situation.

Step 3: After the manufacturer designs the drawings, provide inspection, and the inspection is correct. We carry out sample production. According to the requirements of the screw, whether it is necessary to open the mold for production. If the mold needs to be opened, it must be agreed with the mold for mold reproduction.

Step 4: After the manufacturer's sample production is completed, confirm the sample and install the sample screw on the product, whether it is suitable. After confirming the sample, we will produce large products.
