The spring washer on the expansion screw is a standard part. Because its opening is staggered and elastic, it is called spring washer. The function of spring washer is to use the sharp angle of the staggered opening to insert into the nut and flat washer to prevent the nut from loosening.
The flat washer is also a standard part. Its function is to evenly distribute the pressure of the nut on the connected parts.
The screw moves outward, and the conical part moves through the axial movement of the thread, thus forming a large positive pressure on the outer surface of the expansion pipe. In addition, the angle of the conical part is very small, so that the friction self-locking is formed between the wall, the expansion pipe and the conical part, so as to achieve the fixed function.
45 steel, for important or special purpose screw connection parts, alloy steel with high mechanical properties such as 15Cr, 20Cr, 40Cr, 15mnvb, 30crmrsi can be selected.
Select different expansion screws according to the actual situation of the wall. Generally, there are the following 6 × 60, 6 × 80, 6 × 120 and 6 × 150.
The expansion screw has the advantages of small drilling, large pulling force and flat exposed after use. If it is not necessary to remove it at will, it can keep the wall flat and has been widely used in various decoration occasions
