The blind rivet nuts (GO-INSERT Family)

Blind rivet nuts make it possible to assembly several elements and can then be combined with screws or bolts.

Advantages of this product :
  • Robust threading on parts with low thickness or resistance
  • Blind setting (access only available on one side) in profiles, tubes or caissons
  • The possibility of combining the riveting and screwing of different parts, on top of blind riveting
  • Will withstand high tightening torque
  • No damage to the treated surface
  • Will withstand frequent unscrewing
  • A short assembly process

INSTALLATION DESCRIPTION


1-Screw the nut on the tool’s mandrel.
2-Insert the nut into the assembly.
3-Set the nut.
4-Unscrew the mandrel.
The set nut is thus ready to receive a screw or bolt.

THE DIFFERENT HEAD SHAPES

Flat Head

This is the most common multi-purpose head.

Countersunk Head
It often requires milling the support surface. The countersunk head will therefore be used when needing a reduced space between assembled parts and when a reduced head cannot be used.

Large Head
Upon request.

Reduced Head

Can be used when needing no or reduced space between assembled parts. Reduced heads can replace countersunk heads because they don't require milling, but they should not be used:
  • if the tolerance of the hole is not controlled,
  • if the support material is malleable (risk of head extraction)
  • if the screw is under bending stress.

THE DIFFERENT SHAFT FORMS
Cylindrical Smooth Shaft

Common use.

Cylindrical Knurled Shaf

To work on soft materials. Shaft design with positive locking anti-rotation device.

Hexagonal shaft

Provides anti-rotation. Suitable for frequent screwing and unscrewing.

Semi-hexagonal shaftl

Unlike the entirely hexagonal shaft, it prevents any unscrewing of the nut with a wrench (which damages the support surface) after installation.

Tensile strength

Tensile strength is the maximum force a nut can bear under axial pressure before breaking (value expressed in Newtons).

Tightening torque

To measure the tightening torque, the nut is placed on a test plate with a steel washer restrained from rotation, then the screw is tightened.
