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
Trin-for-trin 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)
Løste eksempler
Input
M8 metric thread
Resultat
8 mm diameter, UNC equivalent #5-40, similar size
Not exactly interchangeable
Almindelige fejl at undgå
- ✕Assuming metric and inch are compatible (they're not)
- ✕Not checking thread pitch (critical for alignment)
Ofte stillede spørgsmål
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.
