Flat Head Allen Socket Sleeve Square Thread Nut

For different screws, the supporting nuts are also different. There are many types of Flat Head Allen Socket Sleeve Nut. Do you know the types, specifications, uses, and installation methods of rivet nuts? Let's take a closer look.

Types of rivet nuts

Flathead, small head, hexagon, half-hexagon, with through-hole, blind hole, knurled, and non-knurled.

Specifications of rivet nuts

The specifications of Hex Rivet Nut Fastenal in the national standard include M3 M4 M5 M6 M8 M10 M12. M6 and M8 are recommended because if the thread is small, it can be directly tapped on the substrate for connection. If the thread is large, the bolt weight will be greatly increased, and the connection strength of Hex Rivet Nut Fastenal will be limited, that is, the matching is not very reasonable.

It can be seen from the above that Hex Rivet Nut Fastenal can be widely used on aluminum alloy substrates with different thicknesses or steel plates with a thickness of 1-2.5mm. In particular, the connection of steel rivet nuts in aluminum alloy components eliminates the cumbersome work of embedding steel plates inside, and its manufacturability is significantly improved.

Application of rivet nut

If the Square Thread Nut of a product needs to be installed on the outside, and the inner space is narrow, the indenter of the riveter can't enter for riveting, and the sprouting and other methods cannot meet the strength requirements, then neither riveting nor expanding riveting is feasible. Pull riveting must be used. It applies to the fastening field of plates and pipes of various thicknesses (0.5mm-6mm). Pneumatic or manual riveter can be used for one-time riveting, which is convenient and firm; Replace the traditional welding nut to make up for the shortcomings of thin metal sheet, thin pipe welding, fusibility, unsmooth welding nut, and so on.

Installation method of rivet nut

In the use of Hex Rivet Nut Fastenal, although the installation method and principle have been determined, the Hex Rivet Nut Fastenal still needs special riveting equipment for operation, which is also an indispensable factor to ensure that the Hex Rivet Nut Fastenal can maintain a stable working performance after installation. During installation, the head of the riveting press and the Hex Rivet Nut Fastenal shall be kept vertically balanced and pressed down evenly.

A press riveting nut column, also known as a press riveting stud or nut column, is a fastener applied to sheet metal, chassis, and cabinet. One end of the press riveting nut column is hexagonal, the other end is cylindrical, there is a tool withdrawal groove between the hexagonal edge and the cylindrical shape, and its internal shape is an internal thread, Press the hexagonal head into the preset hole of the thin plate through the press (the hole diameter of the preset hole is generally slightly larger than the cylindrical outer diameter of the press riveting stud), to produce plastic deformation around the hole, and the deformed part is squeezed into the tool return groove of the press riveting nut stud so that the press riveting nut stud is riveted tightly on the thin plate, to form an effective fixed internal thread on the thin plate.
