There are some screws, is installed in the electrical, power, electronic products on the material, ask how to correctly install the screws?
A small screw, but has a great impact, how to use a small screw, so that the role of the maximum screw, these are the things we need to learn, we should know that the screws are small, but less screws It is absolutely impossible. We have a good understanding of the correct use of the screw on the method. If we have a screw on our hands, then we can go to understand the characteristics of the screw, you can understand the above raw materials, you can in the specifications, hardness above to understand, we only have a comprehensive understanding of the characteristics of this screw, we To be able to correctly use this screw, otherwise, we will never play a small screw the biggest role.
Expansion screw installation method to expand the screw on the ground or wall holes in the hole, with a wrench to tighten the nuts on the expansion bolts, bolts to go out, while the outside of the metal sleeve is not moving, so the bolt under the bulk of the metal Set up to keep it full of holes, this time, the expansion of the bolt on the expansion of the expansion screw is to make the duct support, hanging, bracket fixed to the wall, the floor, the column used in a special thread connection Pieces. Consists of countersunk head bolts, expansion tubes, flat washers, spring mats and hex nuts. When used, you must first use the impact of electric drill (hammer) in the fixed body on the corresponding size of the hole, then the bolt, expansion tube into the hole, tighten the nut to bolts, expansion tube, the installation and expansion between the fixed body Tight into one. Expansion of the expansion of the principle of expansion of screws is to use the pull out of the slope to promote the expansion of friction caused by clamping force, to achieve a fixed effect. Screw head is a thread, a vertebral. Outside the package of a metal, metal cylinder half of a number of incision, put them together thrown into the hole in the wall, and then lock the nut, Luo mother pull out the screw, the vertebral pull into the metal cylinder, metal cylinder was Open up, so tightly fixed on the wall, generally used for fence, rain Peng, air conditioning and other cement, brick and other materials on the fastening. But its fixation is not very reliable, if the load has a greater vibration, may be loose, it is not recommended for the installation of ceiling fans and so on.
After we understand the characteristics of the screw, we can proceed to the next step. For example, we use the hands of a 8.8-wide hexagonal screws, then we have mastered the 8.8 hexagonal screws, the use of screws can be used to wipe some of the oil, so that we can protect the screws, in the invisible Which extended the life of the screw. And we have to use the 8.8-grade hexagon screw in the process, we will be able to know that we need to properly protect the screw head inside the hexagon, to prevent 8.8 grade hexagon screw skid, because we know 8.8 grade hexagon screw More difficult to take out. Then we can think of this screw should be used in what place? We can not put a small number of digital screws on the large industrial above, so that the screws can not withstand the pressure of large industrial above, so we need is to help the screw to choose a suitable place, so the screw on the matter The value of the.
