Screw thread converters translate between different thread designations: UNC, UNF, metric (M), BSW, etc.
Fórmula
Inch: #10-24 UNC = 10 size, 24 threads/inch
- UNC
- 10 size — 10 size
Guia passo a passo
- 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)
Exemplos resolvidos
Entrada
M8 metric thread
Resultado
8 mm diameter, UNC equivalent #5-40, similar size
Not exactly interchangeable
Erros comuns a evitar
- ✕Assuming metric and inch are compatible (they're not)
- ✕Not checking thread pitch (critical for alignment)
Perguntas frequentes
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.
