Service HotlineThe round nut is often used with the round nut with a stop washer. When assembling, insert the inner tongue of the washer into the groove on the shaft, and insert the outer tongue of the washer into the groove of the round nut, and the nut will be locked; loose. Often used as the axial fixation of rolling bearings. Round nut with thread size of M10×1～M200×3. The thread specification D=M16×1.5, the material is 45 steel, the groove or all heat treatment hardness HRC35～45, the marking of the surface oxidation round nut: nut GB/T 812-88 M16×1.5.
A double-nut self-locking fastener includes bolts, nuts, nuts, and elastic gaskets that can produce plastic deformation under pressure; the nut and the bolt are connected by threads, and one end of the nut is provided with an external thread; There is an inner thread in one end, and the inner thread of the nut and the outer thread of the nut constitute a thread pair; the other end of the nut is provided with a through hole, and the bolt passes through the through hole of the nut; when the nut and the nut are installed and tightened, the elastic gasket is located in the nut. between the bolt and the nut; a notch for cutting off the thread is arranged on the circumference of the bolt thread; the direction of the notch is parallel to the axial direction of the bolt.
Self-locking nuts generally rely on friction. The principle is to press the embossed teeth into the preset holes of the sheet metal. Generally, the diameter of the square preset holes is slightly smaller than that of the rivet nut. The nut is connected with the locking mechanism. When the nut is tightened, the locking mechanism locks the ruler body, and the ruler frame cannot move freely to achieve the purpose of locking; when the nut is loosened, the locking mechanism disengages the ruler body, and the ruler frame edge body movement
The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are that the rivet nut is fixed on thin-walled or thin-plate objects without welding, easy operation, high production efficiency, easy to manufacture, low cost, single-sided riveting, firm connection, no pollution, no noise, Has significant economic benefits.
The gasket refers to the part between the connected part and the nut, which is generally a flat metal ring, which is used to protect the surface of the connected part from scratches by the nut and disperse the pressure of the nut on the connected part.
