Stainless Steel Wedge Anchors (A2 / A4)
Stainless steel wedge anchors use the same torque-controlled expansion mechanism as carbon steel anchors, but in SS304 (A2) or SS316 (A4) for corrosion resistance. They are specified for coastal installations, swimming pools, food processing plants, tunnels and anywhere the anchor will be permanently exposed to moisture.

Frequently Asked Questions
When should I use stainless steel wedge anchors?
In wet, coastal, pool, food-processing or chemical environments where carbon steel (even galvanized) would corrode. A4/316 versions suit the harshest chloride exposure.
