Nickel Alloy Shoulder Screws

Nickel alloy shoulder screws are more resistant to acids and salt water than stainless steel shoulder screws. They may be mildly magnetic. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components, and as an axle or pivot point.
