Metal Wall Plugs / Saw Anchors

Metal Wall Plugs, commonly known as Saw Anchors, Metal Saw Anchors, or Christmas Tree Anchors, are steel expansion plugs used to create mechanical fixings in masonry and other mineral building substrates. Their distinctive serrated outer profile gives the anchor its characteristic appearance and helps it grip the sides of a drilled hole when the fixing screw is installed. The product is also commonly associated with applications where a metal fixing is preferred over a conventional plastic wall plug.

The anchor body is typically manufactured from formed carbon steel and is available in metric sizes such as M5, M6, M8, and M10, with different lengths selected according to the substrate and fixing requirements. Zinc plating is a common finish for carbon steel versions, providing basic corrosion protection for indoor and general-purpose construction applications. Material, finish, dimensions, and load performance should be specified according to the intended application and purchasing requirements.

Metal Wall Plugs are used for fixing electrical accessories, brackets, light fixtures, signs, cable supports, building hardware, and other components to brick, concrete, masonry, and similar substrates. They can be used with compatible wood or chipboard screws, making them practical for installation systems where the screw may need to be removed and reinstalled.

Metal Wall Plugs are manufactured according to established industry dimensions, manufacturer specifications, or customer drawings rather than a single international standard. For B2B purchasing, buyers should therefore confirm the required diameter, length, screw compatibility, material, finish, and application before ordering.
