The functions and roles of expansion screws mainly include the following:
-Connection and fixation: It can firmly connect or fix objects to various substrates, such as fixing metal components, wooden furniture, electrical equipment, etc. to walls, ceilings, or floors, ensuring that they will not easily loosen or fall off during use.
-Provide strong tensile and shear forces: The expansion screw is designed with a special structure. When tightening the nut, the screw will drive the expansion tube to expand, making it tightly fit with the substrate, thereby generating a large frictional and biting force. It can withstand large tensile and shear forces and meet the load-bearing needs in different scenarios.
-Adapt to different substrate materials: Whether on hard substrates such as concrete, brick walls, or stone, or on relatively soft substrates such as wood and plastic, as long as the appropriate expansion screw model and specifications are selected, reliable fixation can be achieved.
-Easy to install and disassemble: During installation, simply drill a hole in the base, insert the expansion screw into the hole, and tighten the nut to complete the installation. If disassembly is required, unscrew the nut and the expansion screw can be removed from the base, and the damage to the base is relatively small, making it easy for subsequent maintenance or component replacement.
