How to solve the bending problem with 300mm screws?

In August, a British customer found Shi Shi Tong and wanted to customize a 300mm screws for their new product development. The customer’s product assembly is mainly in Guangzhou, so the British customer came to Shi Shi Tong with their R&D technicians and wanted to explore how to solve the problem of 300mm long screws being flexible.

The customer brought the samples and drawings of the 300mm screws. Shi Shi Tong first tested the customer’s samples. The customer’s samples were made of carbon steel and the surface was galvanized. The reason why the customer’s sample will bend is that the material selected by the previous supplier is a poor material, but in order to meet the screw strength requirements, heat treatment is needed to provide strength. During the heat treatment, the screw is easily bent by heat.

In the end, Shi Shi Tong suggested that the customer change the material of the 300mm screws to stainless steel 304, which not only enhances the salt spray test time of the screw, but also the strength of stainless steel 304 4.8 can meet the needs of customers. The customer stated that Shi Shi Tong is very professional and will quickly determine the purchase order.
