A wall plug can refer to an electrical outlet or a plastic/metal sleeve used to hold screws in materials like plaster and concrete. Outlet designs vary by region and must meet safety standards. Different types of wall plugs can support varying amounts of weight.

The term “wall plug” has two distinct meanings, one in the context of residential and commercial electrical circuits and the other in the context of general building supplies and building materials. An electrical wall outlet, also known as a socket or receptacle, is the connection point between a pluggable electrical appliance and the circuits in the building. In terms of building materials, a wall plug is a plastic or metal sleeve that can hold a screw into a wall that would otherwise not be able to support it.

An electrical wall outlet, or outlet, being the point of use for all pluggable electrical devices, must meet the safety and efficiency standards set forth by the regulatory agencies in each country. Wall outlet designs vary from region to region around the world because no standard has been adopted for the voltage at which electricity is supplied by power companies. Countries for which the 100 to 120 volt standard have sockets with vertical and horizontal slots, while those for which the 200 to 240 volt standard have round or square holes. In the United States, the design of the outlet is determined by the National Electrical Manufacturers Association (NEMA), and its designs are used in other North American countries.

In construction activities other than those related to electricity, a wall plug has the same meaning as a wall anchor or screw anchor. Some wall materials such as plaster, drywall and concrete cannot hold screws. When you need to drive a screw into these materials, the usual procedure is to drill a hole and insert a wall plug to hold the screw. The hole should be deep and wide enough so that the plug fits tightly when tapped with a hammer and the force of the screw being driven in secures it against the sides of the hole.

The amount of weight a screw anchor can support depends on the material it is made of and its design. A tapered plastic dowel can hold the least amount of weight and is often used to attach lightweight shelving or pictures to drywall and plaster walls. When greater holding force is required, a fastener such as a metal screw anchor, winged or threaded plastic wall anchor, or molly bolt is usually used, which widens at the end as the screw is tightened. screwed. A lead wall plug is usually employed when a screw needs to be driven into concrete.
