Rivets for plastic materials are designed to create permanent joints in components made from plastic. Their configuration allows assembly by riveting without the need for a threaded joint.
The range consists of dome-head rivets available in different diameters and lengths. The catalogue includes two main configurations: FA, with an aluminium Mg 3.5 body and zinc-plated steel mandrel, and ALSOF, manufactured entirely from aluminium Mg 3.
FA and ALSOF rivets for plastic materials
The FA and ALSOF models are intended for applications on plastic materials and both use a dome-head configuration.
The main difference between the two families is the materials used:
- FA: aluminium Mg 3.5 body and zinc-plated steel mandrel.
- ALSOF: aluminium Mg 3 body and aluminium Mg 3 mandrel.
Both configurations are listed in the catalogue in the specific section for rivets for plastic materials.
Characteristics of rivets for plastic materials
- Dome head.
- Designed for plastic materials.
- Installed by riveting.
- Available in different diameters.
- Different lengths to suit the total joint thickness.
- FA version with zinc-plated steel mandrel.
- ALSOF version manufactured in aluminium Mg 3.
FA – Aluminium Mg 3.5 / zinc-plated steel
FA rivets combine a body manufactured from aluminium Mg 3.5 with a zinc-plated steel mandrel. The catalogue includes diameters of 3.2, 4.0 and 4.8 mm.
The 3.2 mm range includes lengths of 8, 10 and 12 mm, while the 4.0 mm range includes lengths from 10 to 30 mm. In 4.8 mm diameter, lengths range from 10 to 50 mm.
FA dimensions
| Diameter | Head Ø | Lengths | Grip range |
|---|---|---|---|
| 3.2 mm | 6 mm | 8–12 mm | 0.5–5 mm |
| 4.0 mm | 8 mm | 10–30 mm | 1.5–24 mm |
| 4.8 mm | 10 mm | 10–50 mm | 0.5–42 mm |
For 3.2 mm diameter, the references are FA3208TT, FA3210TT and FA3212TT. For 4.0 mm, the range includes FA4010TT, FA4012TT, FA4016TT, FA4020TT, FA4024TT and FA4030TT.
For 4.8 mm diameter, the references range from FA4810TT to FA4850TT, with grip ranges up to 37–42 mm for FA4850TT.

ALSOF – Aluminium Mg 3
ALSOF rivets for plastic materials are manufactured entirely from aluminium Mg 3, both the rivet body and the mandrel.
This configuration is available in diameters of 4.0 and 4.8 mm. The catalogue references include different lengths and grip ranges.
ALSOF dimensions
| Diameter | Head Ø | Lengths | Grip range |
|---|---|---|---|
| 4.0 mm | 8 mm | 14–19 mm | 1–7 mm |
| 4.8 mm | 9.6 mm | 15.3–24.5 mm | 1–12 mm |
For 4.0 mm diameter, the references are ALSOF4014TT and ALSOF4019TT. For 4.8 mm diameter, the range includes ALSOF4815TT, ALSOF4821TT and ALSOF4825TT.

Applications
Rivets for plastic materials are intended for permanent joints in plastic components where mechanical fastening by riveting is required.
The availability of different diameters and lengths allows the rivet to be adapted to the joint thickness. The choice between FA and ALSOF mainly depends on the material configuration required for the application.
FA rivets can be used when an aluminium body and zinc-plated steel mandrel combination is required, while ALSOF rivets provide an all-aluminium Mg 3 configuration.
Advantages of rivets for plastic materials
One of the main advantages of this range is the availability of different configurations to suit the characteristics of the assembly.
FA rivets use different materials for the body and mandrel, while ALSOF rivets are manufactured entirely from aluminium Mg 3.
The different available lengths also allow the rivet to be selected according to the total thickness of the materials to be joined.
How to select a rivet for plastic materials
To correctly select a rivet for plastic materials, consider:
- Rivet diameter.
- Rivet length.
- Total joint thickness.
- Hole diameter.
- Rivet material.
- FA or ALSOF configuration.
The catalogue provides the main dimensions and corresponding grip range for each reference. The length should be selected according to the actual joint thickness.
