What are the causes of stainless steel cap screws fracture?

Generally, stainless steel cap screws are not easy to fracture. So under what circumstances does it cut off? Here are four common situations below.

First, the raw materials used for making screws have quality problems. Stainless steel screw wire quality is not good, there are a lot of impurities inside, will lead hardness of stainless steel screw is not enough.

Second, the customer exerts too much force when using stainless steel cap screws. Normally can do torque test,clear their own breaking force, and then adjust the torque.

Third, the process of producing stainless steel cap screws. For example, stainless steel screws with eccentric head, or Q value is too deep and R site design is too small in the case of manufacture work.

Fourth, clear whether the pre-drilling is appropriate or not. If the pre-drilling is too small, the screw will be fractured.

Consequently, we must distinguish carefully when buying stainless steel cap screws, in case buy inferior products. Shenzhen Shi Shi Tong Screw Factory is committed to the production and processing the products with guaranteed quality, if you have needs of customizing screws, please contact us.
