Usage And Application Scenarios Of 9-shaped Hook Expansion Screws

Preparation: Select the appropriate expansion screw specifications (such as M6, M8, etc.), and select the appropriate expansion tube type (such as plastic, metal, etc.) according to the wall material.
Drilling: Drill holes at the installation location. The hole depth is generally about 5 mm more than the length of the expansion tube to ensure that the expansion tube is fully embedded.
Installing screws: Insert the expansion tube into the hole, and then screw the screw into the expansion tube until the conical part of the tail of the screw enters the expansion tube to form friction self-locking.
Fixing objects: Hang the objects to be fixed (such as air conditioners, water heaters, clothes drying racks, etc.) on the screw
