Do metric bolts come in fine thread?
Fastener thread pitch in millimeters and inches. Metric fasteners are usually classified as either coarse or fine, referring to their thread pitch, although some sizes are available in an extra fine thread.

How do I know if my bolts are standard or metric?
For both metric and standard bolts, the head size is the distance across the flats. For standard bolts, the head size is measured in inches or fractions of an inch. For metric bolts, head size is measured in millimeters. However, metric bolt head size is measured in millimeters.
What is the most common M6 thread pitch?
Metric clearance and tapping drill hole sizes.
| Size | Clearance Hole mm | Tapping Drill (std Pitch) |
|---|---|---|
| M5 | 5.5 | 4.2 mm |
| M6 | 6.5 | 5.0 mm |

| M10 | 11 | 8.5 mm |
What is 1.5 thread pitch?
The thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm. In general smaller fasteners have finer thread so they have lower thread pitch.
