The blind rivet nut is a fastener widely used in industry. Friends who don’t know it don’t know how to use it. Today I will introduce to you the use method and precautions of the blind rivet nut.

1. How to use blind rivet nuts

If the nut of the product needs to be installed on the outside, and the internal space is too narrow to allow the indenter of the riveting machine to enter the riveting and methods such as riveting cannot meet the strength requirements, then pressure riveting and expansion riveting are not feasible at this time, and pull riveting must be used. Riveting. It is suitable for fastening plates and pipes of various thicknesses (0.5mm-6mm). Pneumatic or manual riveting guns can rivet at one time, which is convenient and firm. It can replace traditional welding nuts to make up for the welding of metal sheets and thin pipes. Defects such as easy fusibility and uneven welding nut.

2. Precautions when using blind rivet nuts

When using blind rivet nuts, you need to use a rivet nut gun such as a manual rivet nut gun, etc. Before using a manual rivet nut gun, you need to pay attention to the following issues:

1. First check whether the gun nozzle screw is assembled correctly. Select the corresponding gun head and rivet bolt according to the rivet nut size, and check whether the connection between the connecting parts is reliable.

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

3. The scale ring of the rivet nut gun is used to adjust the riveting stroke. It can be adjusted as needed during operation. It is worth noting that when adjusting the length of the riveting bolt, you need to open the 2 handles and adjust the gun head sleeve. The exposed length of the rivet bolt can be slightly larger than the length of the rivet nut, so the adjusting nut and the gun body should be tightened together.

4. Then, open both hands and pull out all the bakelite. Put the corresponding rivet nut on the end of the rivet bolt and pinch it firmly. Push the bakelite to screw on the gun head bolt. Then insert the rivet nut into the rivet and pre-drill it. hole, and then press the two handles together hard. At this time, the rivet nut expands to rivet the workpiece tightly. Then pull out the bakelite ball, and the blind rivet nut will withdraw from the threaded hole. The installation of the blind rivet nut can be completed.
