  Blind rivet nuts are a new type of fasteners specially used on thin plates, also known as the friends of thin plates. This kind of blind rivet nuts are nuts that provide internal threads. After the blind rivet nut is riveted to the thin plate with a riveting tool, a very suitable internal thread is obtained, and then the screw or other can be installed.
  If the nut of a certain product needs to be installed on the outside, and the space inside is small, the indenter of the squeezing machine cannot be used for squeezing and the method of sprouting cannot meet the strength requirements, then the pressure riveting and the expansion riveting are not feasible. Must use pull riveting. It is suitable for the fastening field of various thickness plates and pipes (0.5MM-6MM). The use of pneumatic or manual riveting guns can be used for one-time riveting, which is convenient and firm; it replaces the traditional welding nut to make up for the shortcomings...    less

  We can use many kinds of rivet nuts. There are two major categories, blind rivet nuts and sub-rivet nuts, not to mention other small categories. Today, let’s talk about half hex rivet nut nut and hex rivet nut.
  As the name suggests, half hexagon rivet nuts have a half hexagon cylinder and a half cylinder, while full hexagon rivet nuts are all hexagons. There are many types of hexagonal rivet nuts, including flat head, small head, hexagonal, semi-hexagonal rivet nuts, through holes, blind holes and the difference between knurled and non-knurled.
  In terms of shape difference, the rivet nut has the function of stopping rotation. The hexagonal blind rivet nut is a hexagonal prism, and the round one is a cylindrical straight grain. The key is to choose according to the use occasion. Pressure riveting nuts are also called riveting nuts. Self-tightening nuts are nuts applied to thin plates or sheet metal. The shape is round, with embossed teeth and guide grooves at...    less

  At present, China is the country with the longest high-speed rail operating mileage, the largest under construction, the most EMU operations, and the highest commercial operation speed in the world. As EMU enters the maintenance cycle, the maintenance market for rail transit fasteners is huge. However, with the large-scale and continuous improvement of the power and speed of various rail transit vehicles, higher requirements are put forward on the working conditions of rail transit fasteners. Fracture failure of auto fasteners is a huge hidden danger. Affect the safe operation of rail transit vehicles. Let's take a look at its material and structure.
  The raw materials of railway fasteners are alloy steel or boron-containing steel, and the chemical composition should comply with relevant national standards; 10.9 and above bolts, screws and studs should be made of alloy steel and contain at least one of the following elements: Cr, Ni , The total content...    less

  Auto fasteners and rail transit fasteners can be said to be the basis of the transportation manufacturing industry, because it determines the performance and safety of various automobiles. Fasteners in the automotive industry generally use steel as a raw material. Although non-ferrous metals and certain composite materials are increasing year by year, their high-end and toughness are essential for auto fasteners.
  The size of auto fasteners is small, but the types are indeed diverse. As a small part of the host, it is often overlooked. On the surface, the output value of fasteners only accounts for a few percent of the automotive industry, but in fact, it brings higher added value to key components and automobiles. There are many types of auto parts, but there are only four main categories: standard fasteners, other standard mechanical components, other non-standard mechanical components and non-standard fasteners. Among them, the most economically valuable are...    less
