A zinc plating provides corrosion resistance in wet environments. Use these anchors for permanent, high-strength anchoring where vibration is present. To install, fill a clean, drilled hole half full with epoxy adhesive, then insert the anchor until it's flush with the surface. Pull-out strength values are 25% of the ultimate values.
