Πώς να υπολογίσετε το Screw Thread Converter

Τι είναι το Screw Thread Converter;

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

Τύπος

Inch: #10-24 UNC = 10 size, 24 threads/inch
UNC
10 size — 10 size

Οδηγός βήμα προς βήμα

  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)

Worked Examples

Εισαγωγή
M8 metric thread
Αποτέλεσμα
8 mm diameter, UNC equivalent #5-40, similar size
Not exactly interchangeable

Common Mistakes to Avoid

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

Frequently Asked Questions

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.
