What Is a Plug Anchor?
Plug anchors are used to facilitate screw installation.
A hole is drilled in the base material and the plug is inserted. A screw can then be easily fixed by simply hammering it into the plug anchor. They can be attached to various base materials such as blocks, concrete, and hollow walls, and can be easily removed with a screwdriver.
Usage of Plug Anchors
Plug anchors are used to install screws in base materials. Since they adhere to hard materials, they are useful for concrete. They can also be used for other base materials such as hollow walls and ALC. Applications include the installation of shade trees and interior underlayment, saddle installation of wiring and plumbing, and the installation of lighting fixtures.
Structure of Plug Anchors
Plug anchors consist of a cylinder made of nylon or other material and metal screws. When using a plug anchor, drill a hole in the base metal and clean up any dust. After inserting the plug anchor firmly, drive the screw into it using a hammer or similar tool. The gap between the screw and the base metal will be filled by the screw, and the plug will stick to the base metal.
When screws are driven into concrete, the base material itself may crumble or become brittle, making installation difficult. By utilizing a plug anchor, the ground contact area of the base material is expanded to facilitate attachment.
