Bolt basic properties
Option |
Description |
Default |
---|---|---|
Bolt size |
Bolt diameter. |
Available sizes are defined in the bolt assembly catalog. |
Bolt standard |
Bolt standard to be used inside the component. |
Available standards are defined in the bolt assembly catalog. |
Tolerance |
Gap between the bolt and the hole. |
|
Thread in mat |
Defines whether the thread may be within the bolted parts when bolts are used with a shaft. This has no effect when full-threaded bolts are used. |
Yes |
Slotted holes
You can define slotted, oversized, or tapped holes.
Option |
Description |
Default |
---|---|---|
1 |
Vertical dimension of slotted hole. |
0, which results in a round hole. |
2 |
Horizontal dimension of slotted hole, or allowance for oversized holes. |
0, which results in a round hole. |
Hole type |
Slotted creates slotted holes. Oversized creates oversized or tapped holes. No hole does not create holes. |
|
Rotate Slots |
When the hole type is Slotted, this option rotates the slotted holes. |
|
Slots in |
Part(s) in which slotted holes are created. The options depend on the component in question. |
Bolt assembly
The selected check boxes define which component objects (bolt, washers, and nuts) are used in the bolt assembly.
If you want to create a hole only, clear all the check boxes.
To modify the bolt assembly in an existing component, select the Effect in modify check box and click Modify.
Bolt length increase
Define how much the bolt length is increased. Use this option when, for example, painting requires the bolt length to be increased.
