Threaded Studs

Threaded studs are for thin-gauge base materials.

Copper-Plated Steel—Copper-plated steel studs have good corrosion resistance.

18-8 Stainless Steel—18-8 stainless steel studs are more corrosion resistant than copper-plated steel studs.

Aluminum—Aluminum studs are more lightweight than steel or stainless steel studs. They’re nonmagnetic. In wet environments, they resist corrosion.
