Setting blind rivet nuts means inserting simple threads into a thin-walled object on one side. The shapes are round or hexagonal nuts. In contrast to the general term ‘blind riveting’, where non-detachable connections are produced, “setting blind rivet nuts ’ involves preparing a detachable screw connection.
Blind rivet nuts are primarily used in the automotive industry. Here, thin-walled materials are used in frame structures in car body construction, but also in battery production, in order to ensure high stability with low weight. One-sided accessibility requires the use of blind rivet nuts so that load-bearing threads can be created in these structures. The blind rivet nut thus creates the prerequisite for detachable connections in e-mobility.

Mr. Untch is responsible for product management, including control and drive technology, as well as all WEBER setting systems. This includes insertion and press-in units, as well as the SBM blind rivet nut setting system. With his many years of experience as a developer of mechatronic systems and a quality management representative, he can draw on an extensive wealth of experience that enables him to competently oversee these products.
While other manufacturers turn the nut in their system until it is pulled into the pre-cut hole, WEBER focuses on precision installation. We define the precise position of the hole in advance so the blind rivet nut can be positioned correctly. The system does not have to “search” for the hole first.
Blind rivet nuts can be set in any direction: horizontally or vertically (can also be mounted on a robot). The settings are made in advance.
The force that has to be applied to produce the bulge during blind rivet installation is up to 25 kN (= deformation force).
Blind rivet nuts that can be combined with the WEBER system typically have the following parameters.
Sizes: M4 to M10
Head diameter: up to 20mm
Length: up to 30mm
Material: Stainless steel, steel, aluminium
Shapes: round, hexagon
Of course WEBER can also work with custom items on request.
The difference between round and hexagon nuts is in the shape and function. Blind rivet nuts with hexagon shaft offer a higher level of reliability because they can withstand a higher torque.
The installation unit is either stationary or mounted on a robot or gantry.
The cycle time depends significantly on the size and shape of the blind rivet nut, as well as the length of the thread.
With the WEBER setting unit for blind rivet nuts, cycle times as short as 6 seconds can be reliably achieved.
