ISO 228-1 pipe threads must be parallel and match designated size
Rule Card¶
| Field | Value |
|---|---|
| Pack | F_OVERLAY — Industry Overlay and Compliance |
| Title | ISO 228-1 pipe threads must be parallel and match designated size |
| Severity | critical |
| Check logic | Hybrid |
| Applies to | Compliance overlay |
| Inputs required | hole_features |
| Fix template | Replace tapered threads with ISO 228-1 parallel geometry (or change the callout standard) and confirm the mating component uses the same designation. |
Short Description¶
Checks that modeled ISO 228-1 pipe threads are parallel (not tapered) and match the designated nominal size for manufacturability and assembly interchangeability.
When It Applies¶
This rule runs only when an overlay activates F_OVERLAY. It targets Compliance overlay.
