Stainless steel rivet nuts, also known as pull rivet nuts, are widely used in the furniture and decoration markets. Developed to address the shortcomings of welded nuts on thin metal sheets and thin tubes, such as the tendency for them to melt and the tendency for internal threads to slip, stainless steel rivet nuts require no internal threading or welding, resulting in secure, efficient, and easy-to-use connections.
Stainless steel rivet nuts can be riveted to a single sheet or two sheets together, serving as both a rivet and a nut. They are also suitable for closed workpieces that can only be accessed from one side. Furthermore, for light metal workpieces requiring threaded connections, stainless steel rivet nuts offer a compact and convenient insert design.
Stainless steel rivet nuts are available in flat, small-head, hexagonal, and semi-hexagonal configurations, with through-holes, blind holes, and knurled and unknurled options.
Stainless steel rivet nuts are widely used for connecting panels in industries such as shipbuilding, vehicles, aviation, electrical appliances, instrumentation, metal cabinets, and elevators. They offer easy operation, reliable connections, aesthetically pleasing aesthetics, and low energy consumption and high efficiency. The deformation of stainless steel rivet nuts is similar to the bulging process of a tubular component or pipe, and the degree of bulging deformation is generally expressed by the bulging coefficient.
Because stainless steel rivet nuts deform under axial pressure at both ends, they withstand less stress than bulging under radial pressure within tubular components or pipes. After riveting, stainless steel rivet nuts shrink in length, with the amount of shrinkage related to the material's plasticity and dimensions. To prevent the bulging coefficient from exceeding the allowable value and causing cracks, the shrinkage must be controlled.
