In the automotive sector, self-drilling screws are utilized for assembling various components, ensuring that parts stay securely fastened despite vibrations and shifting. Similarly, in HVAC systems, they secure ducts and other metal components, contributing to the overall efficiency and stability of the installation.

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.
