What is a blind rivet?

Blind Rivets

Blind rivets are a type of rivet. They are used to reliably join a range of materials together with lasting effect. A blind rivet combines a number of advantages in one solution, including providing access to the blind side in an application. Blind rivets come in a wide range of forms, materials, shapes, lengths and even colours. Blind rivets produced by GESIPA® guarantee a high-quality, neat connection that looks good every time.

Blind rivet setting process

During the setting process, the mandrel body is moved using the setting tool jaws, deforming the hollow rivet until it is firmly positioned in the component as predefined. In the end, the mandrel body breaks off at the specified point (the predetermined breaking point) and can be disposed of via the recycling system. The rest mandrel is the spent mandrel left behind in the hollow rivet and can provide an additional locking function depending on the application in question.

How does a rivet work?

A blind rivet consists of two parts: the hollow rivet and the mandrel body. The hollow rivet has a setting head and a rivet body. The setting head is located on the processing side and is available with a range of diameters and in different forms. The head variants are as follows: dome head, countersunk and large flange. The rivet body comes in different lengths that will depend on the thickness of the material to be riveted. The job of the mandrel body is to deform the rivet body. It has a predetermined breaking point, at which the mandrel body breaks off once the rivet has been deformed sufficiently. The filling section is the portion of the mandrel body that is left behind in the hollow rivet. The spent mandrel is the portion of the mandrel body that is removed from the set rivet using a  blind rivet tool and disposed of.

GESIPA® Blind Rivets

Whatever rivet you require, GESIPA® has you covered. Whether you are looking for alu, steel, painted or anodised rivets, the standard rivet range has the right material combination and size for every application. You may even consider a PolyGrip® blind rivet which has a large clamping area and that can replace up to five different sizes of standard DIN rivets. Or even the MEGA GRIP®, which is a high-strength structural rivet with a wide grip range that is designed for particularly complex connections.
