Sealed rivets are designed to create permanent joints when, in addition to mechanical fastening, it is necessary to limit the passage of air, water or other elements through the fastening point.
Their design allows installation from only one side of the workpiece, forming a rear closure during riveting that helps maintain the sealing of the joint. The catalogue includes different head configurations, materials, diameters and lengths to suit different applications.
Sealed Rivets TST
Within the sealed rivet range, the catalogue mainly includes dome head and countersunk head rivets.
The TST-AL family is manufactured with an aluminium Mg 5 head and a steel mandrel. It is available in TST-AL-TT dome head configuration and TST-AL-TS countersunk head configuration.
Characteristics of sealed rivets
- Specifically designed for sealed joints.
- Installation from only one side.
- Available with dome head or countersunk head.
- Head manufactured in aluminium Mg 5.
- Mandrel manufactured in steel.
- Different diameters and lengths available.
- Grip ranges adapted to each reference.
TST-AL-TT dome head sealed rivets
TST-AL-TT rivets are dome head sealed rivets manufactured with an aluminium Mg 5 head and a steel mandrel. The catalogue includes diameters of 3.2, 4.0, 4.8 and 6.4 mm.
The dome head configuration provides a bearing surface on the material and is the main solution within the sealed rivet range.
TST-AL-TT dimensions
| Diameter | Head Ø | Available lengths | Grip range |
|---|---|---|---|
| 3.2 mm | 9 mm | 6–12 mm | 1–8 mm |
| 4.0 mm | 11 mm | 8–15 mm | 1–10.5 mm |
| 4.8 mm | 13 mm | 8–25 mm | 1–20 mm |
| 6.4 mm | 16 mm | 13–16 mm | 5–9.5 mm |
The catalogue includes references such as TSTAL3206TT, TSTAL3207TT, TSTAL3209TT, TSTAL3211TT and TSTAL3212TT for the 3.2 mm diameter.
For the 4.8 mm diameter, references range from TSTAL4808TT to TSTAL4825TT.
TST-AL-TS countersunk head sealed rivets
TST-AL-TS rivets are the countersunk head version of the TST-AL sealed rivet range. Like the dome head version, they use aluminium Mg 5 for the head and steel for the mandrel.
The countersunk head allows the rivet to be integrated into the surface of the workpiece when the application requires a fastening with less projection.
The catalogue includes diameters of 3.2, 4.0 and 4.8 mm.
TST-AL-TS dimensions
| Diameter | Mandrel Ø | Available lengths | Grip range |
|---|---|---|---|
| 3.2 mm | 3.3 mm | 7–13 mm | 1–9 mm |
| 4.0 mm | 4.1 mm | 9.5–14 mm | 2–9 mm |
| 4.8 mm | 5.0 mm | 10–24 mm | 2.5–18.5 mm |
References in this family include TSTAL3207TS, TSTAL3208TS, TSTAL3210TS, TSTAL3212TS and TSTAL3213TS for the 3.2 mm diameter.
For the 4.8 mm diameter, the catalogue includes references from TSTAL4810TS to TSTAL4824TS.
Applications
Sealed rivets are particularly suitable for joints where permanent fastening must be combined with the need to maintain the sealing of the assembly.
They can be used in different metallic constructions and components where the riveting point must provide greater protection against the passage of elements through the joint.
The choice between a TT dome head and a TS countersunk head will depend on the geometry of the surface and the finish required on the outer area.
Advantages of sealed rivets
The main advantage of this family is that it is specifically designed for sealed joints, combining mechanical fastening with a configuration intended to limit passage through the joint.
The range also offers two head geometries, allowing you to choose between a dome head solution or a countersunk configuration depending on the assembly requirements.
The use of aluminium Mg 5 for the head and steel for the mandrel provides a specific configuration for this rivet family.
How to select a sealed rivet
To select the correct sealed rivet, the following factors should be considered:
- Rivet diameter.
- Rivet length.
- Total thickness of the materials to be joined.
- Head type: dome head or countersunk head.
- Hole diameter.
- Head and mandrel material.
The catalogue provides the main dimensions and corresponding grip range for each reference, so the rivet length should be selected according to the actual thickness of the joint.
