Crimp Nuts

The blind rivet nut is used to join several components and can be subsequently fitted with screws or bolts. 

 

The advantages of this product: 

- Robust threading on parts of low thickness or strength 

- Blind installation (accessible from one side only) in profiles, tubes or boxes 

- In addition to blind riveting, combinations of riveting and screwing of several parts are possible 

- Guaranteed resistance to high tightening torques 

- No damage to the treated surface and no deformation of the substrate 

- Resistance to frequent unscrewing - Short assembly time

 

Description of the installation

The crimping nut is automatically screwed onto the tool's pull screw until it contacts the installation nose. It is then inserted into the hole in the workpiece. During riveting, the threads of the insert nut are drawn back towards the tool, forming a bead on the back of the workpiece. The crimped nut is then ready to receive a screw or bolt.

The different head shapes

Flat head

This is the most common and versatile head.

 

Countersunk head

This often requires a countersink in the substrate. The countersunk head is therefore used when a small space is required between the assembled parts and the reduced head is not suitable.

 

Reduced head

To be used when no or little space is required between the assembled parts. Reduced heads can be used instead of countersunk heads as they do not require countersinking, but they should not be used:

- if the tolerance of the hole is not controlled, 

- if the support is malleable (risk of extraction of the head), 

- if the screw works in flexion
