Made of 18-8 stainless steel, they’re nearly as strong as steel but won’t rust in outdoor or washdown environments.

These metric 316 stainless steel shoulder screws are more corrosion resistant than 18-8 stainless steel shoulder screws. They also have excellent resistance to chemicals and salt water.

These screws have a head height about one-third the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.
