Screw thread converters translate between different thread designations: UNC, UNF, metric (M), BSW, etc.
Rumus
Inch: #10-24 UNC = 10 size, 24 threads/inch
- UNC
- 10 size — 10 size
Panduan Langkah demi Langkah
- 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)
Contoh Terpecahkan
Masukan
M8 metric thread
Hasil
8 mm diameter, UNC equivalent #5-40, similar size
Not exactly interchangeable
Kesalahan Umum yang Harus Dihindari
- ✕Assuming metric and inch are compatible (they're not)
- ✕Not checking thread pitch (critical for alignment)
Pertanyaan yang sering diajukan
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.
