✅ Accuracy: 0.0001 in (0.00254 mm)
✅ Anvil/Spindle: flat, 0.256 in (6.50 mm) diameter
✅ Faces: hardened, precision-ground, carbide-tipped, micro-lapped
✅ Flatness: 0.0003 in (0.00762 mm)
✅ Thimble: friction or ratchet-stop for constant force

💡 What is a handy tool for precise outside measurements in metalworking?

- Micrometers are handheld tools that measure outside dimensions with a calibrated screw and vernier scale.
- They deliver high-precision readings to 0.0001 inch, critical for tight tolerances.
- Use constant force with a friction or ratchet-stop thimble for repeatable results.
- For mixed inch and metric specs, note both units to avoid misreadings.
