Braun Fibreboard Screw & Expansion Tube-Gray

Brand :BRAUN
Material :Plastic
Color :Gray
Features :The package contains 5+5 pieces of screws and expansion tubes with sizes 4×40 mm and 6×40 mm.
Expansion tubes have an expansion design that spreads the anchoring force within the wall material (solid or hollow). They also often include anti-rotation fins or protruding edges to prevent the plug from spinning when the screw is tightened.
Chipboard screws have sharp, coarse, and typically full threads designed to grip soft materials like chipboard or MDF effectively without splitting the material. They often have a countersunk or flat head style, allowing them to sit flush with the surface when installed
