Should you pay attention to these 2 points when purchasing stainless steel pan head screw?

Pan head screws are a type of head that is often used with screws. In all cases where the dimensions are certain, what should you pay attention to when purchasing stainless steel pan head screw?

1. What grade ofstainless steel pan head screw

Sometimes the person responsible for purchasing will be very general with the manufacturer that I need stainless steel pan head screw, then the general manufacturers will default to their factory often stainless steel grades, some are 201, some are 304, some are 303 and other different grades But they are all made of stainless steel. Different grades of stainless steel are not the same price and performance is different. Therefore, when purchasing stainless steel pan head screw, it is necessary to specify what grade of stainless steel.

2. Do you want to pass the salt spray test? How many hours of salt spray testing?

In the case that the buyer does not specify, the general screw manufacturer will not mark the salt spray test for electroplating when the stainless steel pan head screw is electroplated. The electroplating factory generally processes it according to the conventional electroplating. . When the buyer receives the goods for use, they will find that they have not been used for a long time and have been corroded after a while.
