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 w...
