Expanding metal wall anchors are designed to hold heavy items by distributing the load across a larger area within the wall. They typically consist of a metal sleeve that expands when a screw is driven into it. This expansion action grips the surrounding material, creating a solid anchor point that can support significant weight. They are particularly useful in scenarios where traditional screws might loosen over time, such as in drywall installation or when hanging items from concrete surfaces.

Rigid insulation nails are typically made of durable materials such as galvanized steel or stainless steel to ensure they can withstand the elements and provide long-lasting support for the insulation board. They are available in a variety of lengths to accommodate different thicknesses of insulation board and come with a washer or base plate to help distribute the weight of the insulation evenly and prevent it from pulling away from the substrate over time.
