Hexagonal rivet nuts, also known as blind rivet nuts, pull caps, instant pull caps, are used in the fastening fields of various metal sheets, pipes and other manufacturing industries. They are widely used in automobiles, aviation, railways, refrigeration, elevators, switches, instruments, Assemble furniture, decoration and other electromechanical and light industrial products. It was developed to solve the shortcomings of thin metal plate and thin tube welding nuts, such as easy melting and easy sliding of internal threads. It does not require internal threads to be tapped, no welding nuts are required, and the riveting is firm, efficient, and convenient to use, such asHalf Hex Rivet Nut.

There are flat head, small head, hexagon, half hexagon rivet nuts, with through holes, blind holes, knurled and non-knurled.

If the nut of a certain product needs to be installed on the outside, and the space inside is small, the indenter of the sub-riveting machine cannot be used for pressure riveting and methods such as sprouting cannot meet the strength requirements, then pressure riveting and expanding 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 riveted at one time, which is convenient and firm; it replaces the traditional welding nut to make up for the shortcomings of thin metal plate, thin tube welding, and welding nuts are not smooth.

The first is to inspect the materials required for the production of the pressure riveting nut, and inspect its wire. Pressure riveting nut wire rods are usually ordered by manufacturers from professional wire rod factories, and their own companies do not produce wire rods. At this time, we tell the wire manufacturer what specifications, model, size, and size of wire are needed. When you order back, you have to check the material of the wire. What we need is iron wire, which must be iron, and stainless steel wire must be stainless steel. Then inspect the specifications, models, sizes and other aspects. See if we can meet our requirements.

In fact, the production process of pressure riveting nuts is inspected. Punched out from the nut machine, punched and formed, various shapes, specifications and dimensions are inspected to see if it can meet the customer's requirements, or the sample requirements given by the customer, or the drawing requirements drawn by us based on the customer's sample . After the punch test is completed, we are checking the tapping. All threads of pressure riveting nuts are inspected. See if we can meet the rules of pass and stop, achieve pass rules and stop rules.

At this time, some pressure riveting nuts are made of carbon steel, that is, iron, and need to be electroplated and electroplated in different colors. The color of the electroplating is determined according to customer requirements. Some customers need environmental protection, and some ordinary electroplating will do. Electroplating inspection also has many aspects, including plating color, salt spray test time reached after plating, etc. When we are electroplating, we often encounter the problem of poor electroplating, so what should I do if the pressure riveting nut is poorly electroplated? This is a problem we ponder over and we need to find a solution.

Finally, it is the inspection of the pressure riveting nut when it is shipped. When shipping, pick out defective products. Only qualified products can be used by customers. Find bad product quality problems in time and control the quality well.
