Pack of 10 M5 x 25 metal anchors for cavities and hollow walls, robust for home decoration and fixing to cavities and plasterboard walls

【Premium Material】The hollow cavity metal anchor fixings are made of grade 4.8 carbon steel with a galvanized surface for good hardness and resistance to deformation; the galvanized layer provides good corrosion and rust resistance for long-term use.

Firm Fixing: The hollow cavity metal anchors come with a hollow jack bolt and nut. When the bolt is pulled firmly outward, the nut tightens with it, creating a petal shape on the plate and securely clamping the plate to hold the item firmly in place, preventing it from easily falling. [Suitable for Hollow Materials] Hollow bolt anchors are specially designed for use with hollow materials and can be used with plate as thick as 0-5mm/0.19 inches, making them ideal for hollow doors, hollow walls, or hollow plywood. [Easy to Install] Hollow cavity anchors can be installed in just a few steps. 1. Drill a hole the same width as the metal retaining nut. 2. Insert the anchors into the holes and adjust the screws in the anchors. 3. Tighten the bolts with a tool, turning them outward until the nuts are fully closed and snug. 4. Attach the item to the nuts with the screws and tighten with a screwdriver. 【Wide Application】Hollow anchor bolts can be used for any shallow hollow plate with a thickness of 0-5mm/0-0.19in. They can be installed on sheet metal, hollow doors, hollow walls, panels, hollow plastic pipes, and more to secure objects, hang objects, etc.
