There are many types of nuts, and there are nuts of different materials. Each type of nut has different specifications, and each type of screw also has its mechanical properties and functions.
Guangdong Yueluo Hardware Industry Co., Ltd. relates to a rivet nut fastener, which includes a body, and the rivet part of the body extends into the product to be processed. It is characterized in that trapezoidal teeth are formed on the joint surface of the body and the product to be processed. Or triangular teeth, there is a circular groove below it, and the height of the riveting part is 0.5-1mm smaller than the thickness of the processed product. Guangdong Yueluo Hardware Industry Co., Ltd. is suitable for riveting of any sheet metal materials, such as carbon steel plate, copper plate, aluminum plate, stainless steel plate, aluminum alloy plate, etc. Solid, high riveting surface flatness, providing good electrical contact performance.
Plastic tree rivets are also called inverted tooth plastic rivets, also known as Christmas tree plastic rivets. The toothed flakes have good elasticity and can be directly manually pressed and installed in the round holes of the interference assembly. The toothed flakes can be installed according to the actual thickness and size. It can be fixed by self-adjustment. The design of the inverted tooth type is that the rivet is firmly fixed to the installation surface after installation, and it is not easy to be pulled out. It is suitable for fixing between soft materials such as foam, wood, rubber, and automobile interiors. Plastic tree rivets have excellent insulation, fire resistance, non-magnetic, heat insulation, light weight, high temperature resistance, high strength, corrosion resistance, and are widely used in various industrial fields.
Metric threads are measured in MM (millimeters) and have a cusp angle of 60 degrees. Both US and Imperial threads are measured in inches. The cusp angle of the American thread is also 60 degrees, while the cusp angle of the imperial thread is 55 degrees. Due to the different units of measurement, the representation methods of various threads are also different. For example, M16-2X60 represents a metric thread. His specific meaning is that the nominal diameter of the screw is 16MM, the pitch is 2MM, and the length is 60MM. Another example: 1/4—20X3/4 means the inch thread, what he specifically means is the nominal diameter of the screw It is 1/4 inch (one inch = 25.4MM), there are 20 teeth on one inch, and the length is 3/4 inch. In addition, if you want to express American screws, UNC and UNF are usually added to the back of the British screws to distinguish between American coarse teeth or American fine teeth. In the usual domestic sales business, the most common standards we encounter are GB (National Standard) and DIN (German Standard). In the production of Yaoda, the following standards are mainly encountered: GB30; GB5783; GB5782; GB52; GB6170; GB818; GB819; GB845; GB846; GB70; DIN912; DIN933; It has been replaced by GB5783 (new national standard). GB52 (old national standard) has been replaced by GB6170 (new national standard) in the standard book.
