The design of a plastic expansion screw typically includes a plastic anchor and a matching screw. The anchor is inserted into a pre-drilled hole in the wall. As the screw is driven into the anchor, the base of the anchor expands, pressing against the sides of the hole. This action secures the anchor in place, providing a stable and strong hold that can support light to medium loads such as picture frames, wall-mounted decorative items, shelving units, and light fixtures.
Easy Installation: They are simple to install, often requiring only a drill to create a hole and no additional tools for expansion. This makes them user-friendly for DIY projects.
Non-Damaging: Plastic expansion screws are less likely to damage or crack delicate materials compared to metal counterparts, which is particularly useful for drywall or thin panels.
Cost-Effective: Generally less expensive than metal expansion screws, making them a budget-friendly option for home improvement projects.
Lightweight: Their lightweight nature makes them ideal for securing lighter fixtures, such as picture frames or small shelves, without causing undue strain on the material.
Non-Conductive: Plastic expansion screws do not conduct electricity, making them safe for use in electrical installations where insulation is needed.
