To install ceiling fans, chandeliers on ceilings, or install hanging cabinets on concrete walls, expanded titanium metric screw are a very suitable part. The hanging force is large, and the installation is also very simple by mastering the small skills of installing small screws.
This kind of screw has many forms and specifications, but the tomb is composed of three parts: the trunk, the screw and the nut. The installation method is as follows:
(1) Generally, if you hit the wall and hang it horizontally, it is not a problem to lift more than 100 pounds of screws with a diameter of 6 mm. Determine the location on the wall and drill a hole the same diameter as the screw, the depth of which is the length of the screw's trunk.
(2) Hit the trunk with the screw into the hole of the wall, use the screw to pass through the cabinet to be lifted, and tighten the nut. When the screw is tightened, the gap of the trunk is forced to open and stretch around, becoming an inverted shape. , so the hanging force is very large.
In addition, there is a plastic expansion screw whose hanging force is not as large as that of metal, but it is simpler and more convenient to use. Generally, a mirror frame is installed on the wall, and this kind of screw is enough to be safe.
(1) Punch a hole the same size as the screw, and the depth is the length of the screw.
(2) Install the plastic screw trunk in the hole.
(3) Because the main part of the opening is solid, when you screw a wood screw of the same size as the inner diameter of the trunk, the lower part of the trunk is forced to stretch out to form a wedge shape, which can increase the hanging. force effect.
