The Metal Nail-in Anchors are only available in boxes of one hundred. These nails are available in numerous lengths; see our drop down menu for the full list. These nails are uniquely designed to attach many materials directly to brick, stone or concrete. This includes, but is not limited to, suspending ceiling brackets, insulation brackets, dry wall track and brick ties. They are also effectively vandal resistant. The nails themselves are made from zinc coated steel which makes them extra strong and durable. The plug sleeve is made from zamak material. Bulk discounts are also available on this item.
