Plastic Expansion Screw

Plastic expansion screws are widely used fasteners in the fields of construction, machinery, and residential buildings. Their main feature is to use the expansion force of materials to fix objects. This type of screw is usually composed of plastic and steel wire. After drilling a hole in the wall, the screw is inserted into the hole, and then the screw is rotated to expand the steel wire from the inside, thereby achieving a firm fixation of the wall.
Plastic expansion screws have various advantages, including non rusting, easy installation, convenient color matching, good insulation, and strong toughness. It is suitable for various wall materials, such as brick walls, gypsum board walls, and concrete walls, and can provide extremely high fixing force. In addition, plastic expansion screws also have excellent impact resistance and chemical corrosion resistance, making them widely used in the mechanical and construction industries.
