Differences in the models of each rivet nut

January 3, 2024

1. Taking S-M3-1-ZC as an example

A. Material: S represents carbon steel, CLS represents stainless steel, and CLA represents aluminum.

B. Tail size: 0 → 0.76MM (suitable for 0.8MM board).

                   1 → 0.97MM (suitable for plates between 1.0 and 1.2).

                   2 → 1.37 (applicable to 1.5-2.0 sheets).

(-0/-1/-2 is just the code for the tail code, the specific value needs to be checked in PEM, during production and inspection, we can check the packaging labels to see if the rivet specifications are correct).

C. Bottom hole for riveting:

                                          The bottom holes of M2, M2.5, and M3 are all 4.3mm. The C value of the nut is 4.22MM.

                                          The bottom hole of M4 is 5.4mm, and the C value of the nut is 5.38mm.

                                          The bottom hole of M5 is 6.4mm, and the C value of the nut is 6.38mm.

D. SP type rivet nuts: specifically designed for pressing stainless steel materials.

 

2. British rivet nuts: such as S-632-0, S-832-1, etc. The representation method is the same as the metric system except for thread specifications.

 

3. Explanation of the representation method for rivet nuts, taking S-M3-1-ZI as an example:

A. The material is carbon steel (ordinary steel).

B. The thread specification is M3.

C. -1 indicates that the A value of the nut is 0.97MM, suitable for products with a plate thickness of 1.0-1.2mm.

D. Surface treatment is white zinc plated rivet nuts.

 

Note: shank code (0- applicable to plate thickness of 0.8mm, 1- applicable to plate thickness of 1.0-1.2mm, 2- applicable to plate thickness of 1.5-2.0mm).
