Plastic expansion screw is a special type of threaded connector that achieves high-strength connection through the principle of thermal expansion. It uses plastic material to expand after heating, forming a tight connection with the hole wall. The anchoring principle is to generate radial force on the hole wall through the interaction between the plastic expansion sleeve and the conical slope, and then press it in through self tapping screws to increase the force between the plastic expansion sleeve and the hole wall, achieving the required anchoring force. Plastic expansion screws are usually composed of threaded bodies and plastic sleeves, which have good corrosion resistance and are suitable for kitchen and bathroom accessories.
The material of plastic expansion screws is usually polypropylene or nylon, which has the characteristics of light weight and good insulation, and is suitable for occasions with low weight requirements and high insulation requirements. In addition, plastic expansion screws have excellent impact resistance and are not easily cracked during installation, ensuring stability and safety during installation.
