The intumescent screws of hardware screws are generally said to be metal expansion screws, and its fixing principle.
The fixing of the expansion screw is to use the wedge-shaped slope to promote the expansion to produce friction grip and wrapping force to achieve the fixing effect. The screw is threaded at one end and taper at the other. The outer bread is an iron sheet, and there are a number of incisions in half of the iron cylinder, and they are stuffed into the hole made in the wall together, and then the lock nut, the nut pulls the screw outward, and the taper is pulled into the iron cylinder, and the iron cylinder is opened, so it is tightly fixed on the wall, and is generally used for the fastening of protective fences, awnings, air conditioners, etc. on cement, bricks and other materials.
However, it is not very reliable to fix, and if the load is vibrating greatly, it may loosen, so it is not recommended for the installation of ceiling fans or disturbances.
