Expanding plastic screw anchors, often referred to as wall anchors, are designed to secure objects by expanding as a screw is driven into them. Typically made from durable plastic, these anchors are inserted into a pre-drilled hole in the wall. When a screw is inserted into the anchor, it pulls the anchor wings outward, gripping the surrounding material tightly. This expansion creates a hold strong enough to support various weights, making them ideal for a wide range of applications.

One of the primary benefits of using expanding metal wall anchors is their high load-bearing capacity. Compared to plastic anchors, metal anchors provide superior support, especially for heavy items like shelves, TVs, or large picture frames. Their expansion mechanism also ensures that the load is evenly distributed, which minimizes the risk of the wall cracking or the anchor pulling out.

In an era where sustainability is becoming increasingly important, the use of self-drilling screws like the 7% 2016 model can contribute to greener construction practices. By reducing the time and energy spent on pre-drilling and assembly, these screws can lead to lower carbon footprints in construction projects. Additionally, their long-lasting nature reduces the need for replacements and repairs, which further minimizes waste.
