Metal wall anchors are a type of fastener widely used in the fields of construction and machinery. They are mainly used to fix bolts or screws on walls or plates of various materials.

Metal wall anchors are also called car repair wall anchors, expansion bolts or pull-out climbing nails. They are designed to increase friction with the wall by expansion, thereby firmly fixing the connected parts.

Classification and materials of metal wall anchors

Classification by shape: Common metal wall anchors include sawtooth wall anchors, Christmas tree wall anchors, barbed expansion tubes, etc. These different shape designs can adapt to a variety of wall materials, such as lightweight bricks, hollow bricks, etc.

Classification by material: Metal wall anchors are usually made of stainless steel (such as 304 stainless steel), galvanized carbon steel, zinc alloy and other materials to ensure that they have good corrosion resistance and strength.
