As the requirements for the use of electrical appliances in various industries continue to increase, the testing specifications for the performance of various components in electrical appliances are also constantly improving. Riveted contact elements are used in various relays, contactors, small switches, thermostats, etc. in low-voltage electrical appliances. The structure of the riveted contact element generally includes a contact base and a rivet riveted to the contact base. The rivet includes a rivet head and a rivet top, the structure of which is shown in FIG. 1 .

screw is a common connecting piece, a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the parts of the object step by step. Screws are indispensable industrial necessities in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws in televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws are used. Screws and nuts; transportation equipment, airplanes, trams, automobiles, etc. are used together with large and small screws. Screws have important tasks in industry. As long as there is industry on earth, the function of screws will always be important. The screw is a common invention in people's production and life for thousands of years. According to the application field, it is a great invention of human beings. A traditional screw is generally set as a screw head at one end and a screw rod at the other end, which cooperates with an external nut to fasten the connector between the screw head and the nut. However, such as some home appliance modules, chassis and other electrical appliances, the modules and boxes fixed by traditional screws often fasten many parts together by screws. During maintenance, it is necessary to disassemble all parts of the maintenance part, which is very troublesome. Therefore, a new type of screw structure that can be connected at both ends and can realize layered installation is required. During maintenance, only the connecting layer of the maintenance part needs to be disassembled, and neither the exterior nor the interior needs to be disassembled.

The flat screw mainly includes a rotating part and a screw locking part, wherein the rotating part and the screw locking part are respectively flat-shaped structures; At least two sides of the screw lock portion are respectively provided with tooth rows, and the two tooth rows are mutually dislocated, so that the screw lock portion can be locked in a pre-formed screw hole in the workpiece.

The technical solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is: a waterproof rivet, including an integrally formed waterproof cap and a rivet rod for waterproofing, and the waterproof cap includes a lower part that is fixedly connected with the rivet rod. An end face, the lower end face includes a fixing portion arranged in order from the center position of the lower end face to the outside, a buffer portion arranged circumferentially with the fixing portion as the center, and a waterproof portion arranged circumferentially with the fixing portion as the center, the fixing portion and the rivet The rods are fixedly connected, and the section of the waterproof part is a figure-eight shape.

Wood screws, one of which is a polished rod, the angle and pitch of the teeth of the wood screws and self-tapping are different. Self-tapping screws have high hardness, wide thread spacing, deep threads, and uneven surface, while wood screws are the opposite. Another difference is more obvious. Wood screws have no threads at the rear. Self-tapping screws are generally subject to heat treatment, and wood screws are not required. The concept of self-tapping screws is actually very general, because there are many kinds of them according to different head types. Use of wood screws: Similar to machine screws, but the thread on the screw is a special rib for wood screws, which can be directly screwed into wooden components (or parts).

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: high-strength step nuts, mold flange pressure plate nuts, hexagonal long nuts, hexagonal isolation columns and other products, we can provide you with suitable tightening.
