Expanding metal wall anchors, often referred to as expansion anchors or toggle bolts, are hardware devices used to secure objects to walls or ceilings. They are constructed from metal and feature a unique design that allows them to expand within the wall when screw tension is applied. This expansion locks the anchor in place, providing a strong hold that can support significant weight.

3. Sealing Capabilities The primary function of washers is to provide a seal that prevents the ingress of moisture, dirt, and contaminants into bolted joints. EPDM washers achieve this effectively, minimizing the risk of corrosion and wear, which can compromise the structural integrity of components over time.
