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.

INSTALLATION DESCRIPTION
THE DIFFERENT HEAD SHAPES
Flat Head (Tête Plate)
This is the most common multi-purpose head.
Countersunk Head (Tête Fraisée)
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.
Reduced Head (Tête Réduite)
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.
Large Head
Upon request.
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.

MECHANICAL CHARACTERISTICS
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 (value expressed in Newtons).
