Blind rivet nuts

Blind rivet nuts have become an indispensable part modern installation engeneering. They allow to:

- install bolt threads of different types into ...
... thin or low rigidity components
... hollow sections or other components not accessible from both sides
... components which already have a coated surface,
connect different components to each other at the same time and
attach additional parts.

The continous development of new types, forms and dimensions documents the nearly unlimited fields of applications. The HONSEL-Group has been one of the leading companies in this progress for decades.

Blind rivet nuts

Blind rivet nut parallel shank

The classic form of blind rivet nuts for use in dry and grease-free components.

OPTO® Multigrip blind rivet nut

The innovative and patented development of the Honsel-Group was in 2007 the first mass-production multigrip blind rivet nut.

Blind rivet nut knurled

The knurled shaft provides a locking device to avoid the turning of the insert in the component.

Folding blind rivet nut

Folding blind rivet nuts are constructed for those applications where a high pull-out strength is requested.

Folding blind rivet nut

Hollow blind rivet nut

Slotted blind rivet nuts with threaded insert specially for use in brittle or soft materials such as plastic or perspex. Particularly on uneven surfaces, these blind rivet nuts offer outstanding torsional resistance.

Blind rivet nut hexagonal

Blind rivet nuts with continuous hexagonal (Hexaform®) or partial hexagonal shank (Hexatop®) are another possibility to avoid the rotation of the fastener in the component as alternative to knurled shafts.

How does a blind rivet nut work?

Head designs

Flat head

universally useable type of nut with a high level of availability and a wide material spectrum
used with dry and grease-free components

Small countersunk head

The countersinking of the borehole is not normally necessary when machining blind rivet nuts. If technically necessary, the countersinking is to be carried out so that the countersunk head protrudes by min. 0,1 mm after setting.

Countersunk head

For the machining of blind rivet nuts with countersunk head, the component is only to be countersunk to a depth at which the countersunk head protrudes by min. 0,1 mm after setting.

Shank designs

Round shaft blind rivet nuts

universal nut type with high availability and broad material spectrum
use with dry and grease-free components

Blind rivet nuts with hexagonal shaft (Hexatop / Hexaform)

shaft design with positive locking antirotation device
preferred use with coated components
high rotationresistance even with insufficient setting device height
suitable for multiple screwing

Installation

1. Blind rivet nuts are distinguished by simple and rapid installation.

2. To set the nut, it is screwed onto the threaded mandrel of the setting tool, inserted into the component borehole, and set through the tool stroke. This causes the closing bead of the nut to form. After the threaded mandrel is removed, the components can be screwed tight.

3. For installing the nut, various tools are available with which the procedure can be carried out carefully. Setting tools operated by muscle power or by pneumatic hydraulics which can be selected.

Processing blind rivet nuts

Special tools are needed for processing blind rivet nuts. These tools have to be chosen on the basis of the rivet type, the field of application and the processing volume.
