RIVELITTri-fold blind rivet
The Rivelit tri-fold blind rivet, also known as the star rivet, is a high-performance, permanent fastener. It enables the assembly of several parts.
It is called a “blind” rivet because it allows assembly of parts that are only accessible from one side of the parts to be joined. The two parts to be joined must be pre-drilled.
It consists of 2 parts: the rivet body and the rivet stem or nail.
Principles of use :
Setting a blind rivet requires the use of a tool.
This tool can be manual, oleopneumatic or electric, depending on the type of rivet to be set and the type of application.
The blind rivet is inserted into the hole in the parts to be joined. The setting tool pulls the blind rivet stem, deforming the rivet body and stressing the parts and plates to join the parts securely together. When the breaking force is reached, the rivet stem breaks at the break point and is simply discarded.
How to choose the right rivet?
Installing rivets is easy. To ensure success, all you need to do is choose the right rivet.
To do this, you need to ask yourself 3 questions:
- What should the rivet diameter and rivet body material be ? The hole diameter is directly related to the rivet diameter. The rivet diameter, on the other hand, is determined by the strengths required for the application.
- What rivet head do I need ? A flat head provides the best mechanical resistance, while a wide head is ideal for distributing the clamping force more evenly and avoiding deformation of the parts to be joined. The choice is yours !
- How long should the rivet be ? It depends on the total thickness to be crimped.

Different head shapes, materials and dimensions :
Rivelit blind rivets are available in flat head, large (on request) diameter Ø4.0mm; Ø4.8mm; Ø5.2mm with neoprene sealing gasket.
The following materials are available : Alu/Alu, Steel/Steel on request, with sealing gasket for Ø5.2mm.
NB: The first material indicated is that of the body, the second that of the stem.
Surface treatments :
We can offer zinc-plated rivets.
Features of the tri-fold blind rivet :
Like peel type rivets, tri-fold blind rivets can be used to assemble parts on soft materials (plastic, foam, wood, rubber, fiberglass), thanks to their petal-shaped deformation with 3 or 4 arms, which ensures good distribution of the clamping load. However, the main difference between the two types of rivet lies in the fact that the stem head remains enclosed once the rivet has been set.
Ideal for assembly of soft insulating materials.
