Screw thread converters translate between different thread designations: UNC, UNF, metric (M), BSW, etc.

Formel

UNC
10 size — 10 size

Trinn-for-trinn guide

  1. 1Metric: M10 = 10 mm diameter, coarse (1.5 mm pitch) or fine (1.25 mm)
  2. 2Inch: #10-24 UNC = 10 size, 24 threads/inch
  3. 3Non-interchangeable between systems (need washers, adapters)

Not exactly interchangeable

Vanlige feil å unngå

  • Assuming metric and inch are compatible (they're not)
  • Not checking thread pitch (critical for alignment)

Ofte stilte spørsmål

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.
