Can the long screw pass 48 hours salt spray test?

When our screws are used in a particular environment, we need to require the fitting to be suitable for this environment, such as long screw. Otherwise, the parts will soon be corroded, damaged, and unusable. So, can the long screw pass the salt spray test for 48 hours?

Different materials and surface treatment determine how long the long screw can last for the salt spray test, some can not pass the salt spray test, some can only pass the salt spray test of 12 hours, 24 hours, 48 hours, 120 hours, etc. When you select the right material and finish, the screw will pass the 48 hour salt spray test. If you are not sure, you can ask the screw manufacturer, they will recommend suitable material and surface treatment according to your description.

Of course, if the long screw can be tested after 48 hours of salt spray, we also need to consider whether the screw itself can be surface treated, whether the screw will bend after finishing the surface treatment, and whether there is a way to straighten it after bending. Only when you take that into account can you do a surface treatment. Otherwise it will waste our time and money.
