Pressure riveting stainless steel (stainless acid-resistant steel) screws, also known as riveted stainless steel (stainless acid-resistant steel) screws, self-fastening nuts, is a kind of stainless steel (stainless acid resistant) applied to thin sheets (properties: gemological terms) or sheet metal. Steel) screw, the shape of a round, embossed teeth and guide slot at one end. The precision screw not only has a small screw head, but also has a small screw diameter, a short screw length, and a relatively light weight, and some precision screws can be ignored. Precision screw production and manufacturing process requirements are relatively accurate, in terms of tolerance requirements, size requirements and other aspects are very high. Custom screws have an important task in the industry, as long as there is industry on the earth, the function of the screw is always important. Screws are a common invention in people's life and production for thousands of years. According to the application field, it is the largest invention of mankind. The principle is that the embossed tooth is pressed into the preset hole position of the sheet metal. In general, the aperture of the pre-set hole is slightly smaller than the embossed tooth of the rivet nut, and the pressure is pressed by the pressure of the pressure rivet nut. The teeth of the rivet nut squeeze into the plate to cause plastic deformation of the periphery of the hole, and the deformation object is squeezed into the guide groove, thereby producing a locking effect. The riveting stainless steel screws are divided into the quick-cut steel rivet nuts S type, the stainless steel rivet nuts CLS type, the stainless steel rivet nuts SP type and the copper and aluminum rivet nuts CLA type from the material quality, respectively. Environment. Specifications are usually from M2 to M12. There is no uniform national standard for riveting stainless steel screws (approved and issued: National Standardization Authorities), which are commonly used in chassis cabinets and sheet metal industries.
The application advantages of stainless steel (stainless acid-resistant steel) screws are as follows
1, the back of the sheet remains completely embedded;
2, small and exquisite, suitable for all electronic or precision equipment (shèbèi);
3, high resistance to torque resistance;
4, convenient equipment, simply press riveting;
5, specification series, to meet a variety of design requirements. Electrical screws are "quantity products" and are not hand-made artworks. In mass production, they are aimed at achieving high-precision, stable quality and consumer prices
