screw with a gasket aims to provide a screw with a gasket that improves installation efficiency. The technical solution of the screw is that after the screw cap, the connecting rod and the screw rod are processed, the gasket with the installation through hole is processed. The installation through hole is drilled through the connecting rod, and then the end of the screw rod opposite to the connecting rod is processed to form a convex tooth structure by extrusion. At the same time, the outer diameter of the tooth peak of the convex tooth is larger than the inner diameter of the installation through hole, so that the gasket is not easy to be installed. Falling off, the step of manually wearing the gasket is reduced, that is, the workload of the staff is reduced, and the installation efficiency is relatively high. The flange increases the contact area between the screw cap and the gasket, and enhances the friction between the screw cap and the gasket, which can prevent the screw from loosening easily after being fastened and installed, thereby improving the connection stability of the screw. When installing the screw, the fixing part can be snapped into the fixing groove on the installation plane, so as to avoid the washer from rotating with the rotation of the screw when the screw is tightened, which is convenient for the tightening and installation of the screw.

The embossing wheel is used to press the mesh pattern (rolling mesh pattern), and the middle is slotted. After milling, the thread still guarantees 6H accuracy. This knurled copper nut is used in power tools, which is different from other knurled copper nuts. The diamond pattern of this knurled copper nut is located in the middle section of the product, and the diamond-shaped mesh knurling wheel rolls the diamond-shaped flower along the large outer circular step surface.

Spring washers are often called spring washers in the screw industry. Its materials are stainless steel and carbon steel, and carbon steel is also iron. The commonly used spring washers are M3, M4, M5, M6, M8, M10, M12, M14, M16. These specifications are more commonly used. The national standard for spring washers is GB/T 94.1-87, which specifies standard spring washers with a size of 2-48mm. Reference standard GB94.4-85 Elastic Washer Technical Conditions Spring Washer

The lifting ring nut is a part that tightly connects the mechanical equipment. It can be connected together through the inner thread, the lifting ring nut and the screw of the same specification. Lifting ring nuts are often used in conjunction with externally threaded columns to lift various equipment, such as molds, chassis, motors, etc.

The semicircular key is a kind of key, the upper surface is a plane, the lower surface is a semicircular arc surface, the two sides are parallel, commonly known as the crescent key. It is basically the same as the flat key connection method, but it is more convenient to manufacture and disassemble than the flat key, and is especially suitable for the connection between the tapered shaft and the hub. The half-round key transmits torque on the side, but the keyway is deep, which weakens the shaft greatly. Due to the deep keyway, the bottom of the keyway is easily deformed after the shaft is heat treated. Therefore, when the semicircular key and the keyway are assembled in a transitional fit relationship, the interference between the lower part of the semicircular key and the bottom of the keyway often occurs, resulting in difficult or impossible assembly. Assembly situation. In order to solve the above technical problems, the current method is to make the thickness of the semicircular key appropriately thin, so that the semicircular key and the keyway are clearance fit, which brings about a large gap between the upper part of the semicircular key and the keyway, and the semicircular key is in operation. Difficult to locate in the keyway, affecting smooth transmission.
