Screw thread converters translate between different thread designations: UNC, UNF, metric (M), BSW, etc.
Formel
Inch: #10-24 UNC = 10 size, 24 threads/inch
- UNC
- 10 size — 10 size
Steg-för-steg-guide
- 1Metric: M10 = 10 mm diameter, coarse (1.5 mm pitch) or fine (1.25 mm)
- 2Inch: #10-24 UNC = 10 size, 24 threads/inch
- 3Non-interchangeable between systems (need washers, adapters)
Lösta exempel
Ingång
M8 metric thread
Resultat
8 mm diameter, UNC equivalent #5-40, similar size
Not exactly interchangeable
Vanliga misstag att undvika
- ✕Assuming metric and inch are compatible (they're not)
- ✕Not checking thread pitch (critical for alignment)
Vanliga frågor
Can metric and inch threads be used interchangeably?
No, slightly different pitch and angle. Using wrong thread can damage equipment.
What's the difference between coarse and fine pitch?
Fine pitch holds tighter, suits thin walls, vibration-resistant. Coarse easier to assemble, stronger.
