Stainless steel rivet nuts are a type of fastener that provide a strong and secure thread in thin metal sheets. They are ideal for applications that require a high-strength, reliable connection and can be easily installed with a simple hand tool. We could provide such rivet nuts, contact us for a free quote.

Rivet nut, also known as pull cap, instant pull cap, is a new type of fastener specially used on thin plate, which is vividly called "the bosom friend of thin plate". It has a wide range of applications in the field of fastening, especially in the assembly of mechanical and electrical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, decoration, etc. The development of rivet nuts is designed to solve the shortcomings of thin metal sheet, thin tube welding nuts, and easy to slip the internal thread. The head of the rivet nut has flat head, small head, hexagonal, semi-hexagonal, etc., and the distinction of through holes and blind holes, and the classification of knurled and no knurled.

Main features of rivet nuts

1. No tapping of internal thread: Rivet nuts do not need to tap the internal thread in advance on the sheet, simplifying the installation process.

2. No welding: Compared with traditional welding nuts, rivet nuts avoid problems such as fusible and uneven welding.

3. Riveting firmly: The riveting nut is firmly fixed on the sheet through the riveting tool to provide a reliable internal thread connection.

4. Wide range of application: suitable for various thickness of plates, pipes (0.5MM-6MM), to meet different application needs.

5. Easy to use: The use of pneumatic or manual riveting gun can be riveted at a time, easy and quick operation.

How do rivet nuts work?

The working principle of the rivet nut can be said to be the combination of the core rivet and the welding nut. The rivet nut is pulled by the screw above the rivet gun to compress the rivet nut lengthwise, causing a convex deformation on the surface of the end, so as to clamp the riveted object and achieve the riveting effect.

What should I pay attention to when installing rivet nuts?

Rivet nuts are widely used fasteners in recent years. Rivet nuts as a solution to solve some difficult welding equipment and other parts of the connection, to a certain extent, instead of some traditional welding processing methods. The use of rivet nuts requires the use of rivet nut equipment such as: manual rivet nut equipment.

Before using manual rivet nut equipment, you also need to pay attention to the following tips: ‍

(1) First check whether the mouth screw of the equipment is assembled correctly. Select the corresponding equipment head and pull riveting bolts according to the scale of the riveting nut, and check whether the connection of the connecting parts is secure.

(2) Pay attention to the deformation length or displacement of the riveted nut, and then correctly adjust the operating rod Angle.

(3) The scale ring of the riveting nut equipment is used to regulate the riveting stroke, and can be adjusted according to demand. It is worth noting that when adjusting the length of the riveting bolt, it is necessary to open the two handles and adjust the head sleeve of the equipment, so that the length of the riveting bolt is slightly greater than the length of the rivet nut. Finally, adjust the nut and the equipment body and tighten.

(4) Finally, open the two hands, pull out the bakelite, put the corresponding riveting nut on the end of the riveting bolt and pinch firmly, and push the bakelite to screw the equipment head bolt. Then the riveting nut into the rivet parts of the pre-drilling hole, and then hard press together the two hands, at this moment the riveting nut expansion will riveted the workpiece tight, and then pull out the bakelite ball, pulling the rivet nut is withdrawn from the thread hole. The device for pulling rivet nuts can be completed.

Application scenarios of rivet nuts
When the nut of a product needs to be installed outside, and the internal space is small, it is impossible to let the press head of the press riveting machine into the press riveting, and the bud and other methods can not meet the strength requirements, pull riveting nuts become the ideal choice. It is especially suitable for those who have high requirements for fastening strength, but also subject to space constraints.
