The flange surface nut mainly includes a nut body, a flange surface is fixed at one end of the nut body, and a cap is fixed at the other end of the nut body. Has good sealing and corrosion resistance. The flange surface nut mainly includes a nut body, a flange surface is fixed at one end of the nut body, and a cap is fixed at the other end of the nut body; because the cap is set on the nut body, it has better performance when using hexagonal flange nuts. It can effectively prevent rain, moisture, dust and other harmful substances from immersing in the nut body, prevent the nut body from rusting, and greatly prolong the service life of the hexagonal flange nut. Flange face nut: has a larger ratio of support area to stress area, so it can withstand higher preload. Therefore, it is generally used in the fields of automobile engines, heavy machinery and other products. The flange face nut tells you: the diaphragm beam is a structure in which the inside of the box beam (or T beam) is perpendicular to the box body (or beam body), which plays the role of connection and reinforcement. The diaphragm beam of the box beam is poured together with the box beam. Part of the diaphragm beam of the beam is cast together with the T beam, and the connecting part is cast in place after the T beam is hoisted into place and the adjacent T beam embedded steel bars are welded and then the installation template is cast in place. Flange face nut tells you: there is also this term in the design of car cover parts, which is similar to the raised face of the flange.
