Types of Plastic Wall Plugs:

Standard Wall Plugs: Usually made from nylon or PVC, these are used for general purposes like mounting shelves, frames, or light fixtures.
Screw-in Wall Plugs: These plugs have a threaded design that allows the screw to be driven directly into the plug, offering better grip.
Expanding Wall Plugs: These expand as the screw is tightened, creating a strong bond with the wall.
Sizes & Usage: Plastic wall plugs come in various sizes, usually corresponding to the diameter of the screw you plan to use. Choosing the right size plug ensures the screw is held securely. The plug length also corresponds to the depth of the hole in the wall.

Installation Steps:

Drill a hole in the wall to the correct diameter and depth for the plug.
Insert the wall plug into the hole.
Insert the screw into the plug and tighten it.
Plastic wall plugs are useful for mounting objects on walls without needing to drill into studs or support beams. They’re commonly used for lighter loads or in situations where it is difficult to find a stud behind the wall.
