1、 The use of mountain piercing expansion screws
The mountain piercing expansion screw, also known as a pull screw, is a commonly used fixing component in construction and decoration. They are suitable for various substrates such as concrete, masonry, stone, gypsum board, fiberglass, etc., and can fix various objects such as templates, pipelines, electrical conduits, etc.
2、 Characteristics of mountain piercing expansion screw
The characteristic of mountain piercing expansion screws is that they can be expanded during the assembly process without the need for pre expansion before they can function, which makes them more secure on the fixed substrate. In addition, mountain piercing expansion screws have the characteristics of strong bearing capacity and not easy to loosen, making them important fixing components in construction and decoration.
3、 How to use the mountain piercing expansion screw
Firstly, it is necessary to insert a suitable size of through mountain expansion screw into the hole, and then tighten the nut to fix the entire through mountain expansion screw onto the substrate.
2. Then, use an electric drill or manual pulley until the mountain piercing expansion screw is fully expanded and produces bearing capacity during the final tightening process.
3. Finally, fix the object that needs to be fixed onto the mountain piercing expansion screw and apply appropriate force to make them tightly fit.
