-
From the Analysis Setup section of the
Exploration Assistant, select
Connections.
-
Select a circular edge in the model, and choose Bolts
from the context menu.
- Optional:
Enter a descriptive
Name.
-
Select the bolt type:
| Option | Description |
|---|
| Standard |
A bolt with a circular head and nut. The distinction between the bolt head and the nut
is mostly arbitrary. |
|---|
| Countersunk | A
bolt with a conical head and a circular nut. |
|---|
| Tight
Fit | A bolt that is comparable to a standard bolt, but where a standard bolt models frictional
clamping at the head and nut surfaces, the tight fit bolt body transmits
fastener shear loads directly to the cylindrical faces of the bolt hole. |
|---|
| Tight Fit with
Head | A bolt that combines the frictional clamping
of a standard bolt with the shear load transmission of a tight fit bolt.
|

-
To define a
Head support, select a circular edge or a
cylindrical face.
A circular edge is required for standard and countersunk bolts. A cylindrical face is
required for tight fit bolts.
- Optional:
To define a
Nut support, select a circular edge or a
cylindrical face.
A circular edge is required for standard and countersunk bolts. A cylindrical face is
required for tight fit bolts.
The geometry supports for the head and the nut or the blind hole must be concentric.
-
Enter new values for the head and nut diameters.
For standard bolts, you can click 
to make the nut diameter equal
to the head diameter. The Head diameter is available for
standard bolts only. The Nut diameter is available for
standard and countersunk bolts but only if they are defined for through holes.
Tight fit bolts do not use head or nut diameters.
-
To invert the direction of a bolt after it has been created, select
Reverse direction.
-
Enter the
Axial stiffness and
Shear stiffness.
The stiffness values represent the strength of the bolt. The bolt diameter determined by
the supports is used to calculate the rotational stiffness of the connector.
- Optional:
Enter the Torsional stiffness.
- Optional:
Enter the Bending stiffness.
- Optional:
Select Allow preload, and choose one of the following
options:
| Option | Description |
|---|
| Bolt Force |
Specifies the preload by entering the axial force in the bolt. This force is a tension
that pulls the bolt head and nut together. |
| Bolt Torque |
Specifies the preload by a calculation using the torque applied to
the bolt and a torque coefficient. |
-
If you selected Bolt Force, enter the force.
-
If you selected Bolt Torque, enter the torque.
-
To delete a bolt after it has been created, click its glyph and press
[Delete].
The Feature Manager can also be used to locate, edit, or delete
bolts.
The bolt is created and displayed on the
model with graphics indicating the type of bolt. You can edit an existing bolt by
double-clicking it. You can also edit multiple bolts at once. To open the editor from
the Connections panel, select the Edit
icon in the toolbar. To open the editor from the Feature Manager, choose Edit Selected from
the context menu.
