Screw thread converters translate between different thread designations: UNC, UNF, metric (M), BSW, etc.
الصيغة
Inch: #10-24 UNC = 10 size, 24 threads/inch
- UNC
- 10 size — 10 size
دليل خطوة بخطوة
- 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)
أمثلة محلولة
الإدخال
M8 metric thread
النتيجة
8 mm diameter, UNC equivalent #5-40, similar size
Not exactly interchangeable
أخطاء شائعة يجب تجنبها
- ✕Assuming metric and inch are compatible (they're not)
- ✕Not checking thread pitch (critical for alignment)
أسئلة شائعة
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.
