Metal Hollow Wall Anchors

Metal Hollow Wall Anchors are metal cavity fixings used to secure fixtures to drywall, plasterboard, gypsum board, and other hollow panels where there is no solid structural material directly behind the fixing point. The anchor is inserted through a prepared hole, and tightening the screw causes the metal sleeve to deform and expand behind the board. This creates a larger bearing area on the rear face of the panel and holds the fixture against the front surface. The product is also commonly known as a Hollow Wall Anchor, Molly Bolt, Molly Anchor, or Cavity Anchor.

Unlike conventional wall plugs intended for solid masonry, hollow wall anchors are specifically intended for applications where the substrate contains a cavity. Their expanding metal body allows the fixing to clamp the board rather than relying on friction inside concrete or brick. Depending on the design, the anchor can be installed with a screwdriver or a dedicated hollow wall anchor setting tool. Some versions incorporate a pointed end for direct installation, while conventional versions require a pre-drilled hole. The screw can generally be removed after the anchor has been set, allowing the mounted fixture to be detached while leaving the expanded anchor in the wall.

Typical applications include attaching light-duty cabinets, shelves, mirrors, electrical fixtures, brackets, wall accessories, signs, and other interior components to hollow wall systems. Selection should be based on the anchor diameter, overall length, grip range, board thickness, substrate construction, and expected load. Load performance varies substantially with board density, thickness, anchor geometry, and installation conditions, so published load ratings should be treated as product-specific rather than universal.

For B2B purchasing, Metal Hollow Wall Anchors are commonly supplied in metric and inch configurations, with different lengths and grip ranges available for different panel thicknesses. Standard versions are typically produced from steel and supplied with corrosion-resistant finishes such as zinc plating. ChinaBolts can position these anchors for distributors, wholesalers, hardware importers, and industrial buyers requiring standard sizes, bulk quantities, or application-specific configurations.
