Screw thread converters translate between different thread designations: UNC, UNF, metric (M), BSW, etc.
Формула
Inch: #10-24 UNC = 10 size, 24 threads/inch
- UNC
- 10 size — 10 size
Пошаговое руководство
- 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)
Решённые примеры
Ввод
M8 metric thread
Результат
8 mm diameter, UNC equivalent #5-40, similar size
Not exactly interchangeable
Распространённые ошибки
- ✕Assuming metric and inch are compatible (they're not)
- ✕Not checking thread pitch (critical for alignment)
Часто задаваемые вопросы
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.
