Bolt pitch, technically known as thread pitch when referring to any threaded fastener, is a key characteristic that defines the spacing of the threads on a bolt.
Based on the provided reference, the thread pitch is the distance between threads expressed in millimeters. This measurement is taken along the length of the fastener, specifically from a point on one thread to the corresponding point on the adjacent thread.
Understanding bolt pitch is essential for compatibility:
- Measurement: It represents the linear distance between the crest (peak) or root (valley) of one thread and the corresponding crest or root of the next thread, measured parallel to the bolt's axis.
- Units: For metric fasteners, the pitch is directly stated in millimeters (mm). For example, an M8 bolt might have a pitch of 1.25 mm.
- Example: As the reference illustrates, a thread pitch of 1.5 mm signifies that the distance between one thread and the next is 1.5 mm.
| Measurement Term | Definition (Metric) | Example |
|---|---|---|
| Bolt Pitch | Distance between adjacent threads | 1.5 mm |
| Units | Expressed in millimeters (mm) | M10 x 1.5 |
Matching the bolt pitch of a bolt to the thread pitch of a nut or a tapped hole is critical for creating a functional and secure connection.
