Precision micrometers built for repeatable accuracy
Micrometers—also referred to as micrometer screw gauges or micrometer callipers—are compact, robust instruments for fast, highly accurate length measurement of small to medium workpieces. Designed for routine use on the shop floor, these tools combine mechanical reliability with options for digital data capture, making them indispensable where repeatable tolerances matter.
How micrometers work and where they belong in production
Micrometers operate on a finely threaded spindle that brings two measuring faces into alignment with the workpiece; many designs follow the Abbe comparator principle so that the measuring axis and scale are collinear, reducing tilting errors. Typical outside micrometers (bühlermessschrauben) provide readings down to 1/1000 mm (0.001 mm) in analogue form; internal micrometers and specialised two- or three-point gauges enable accurate diameter and bore measurements, while depth micrometers cover depths from 0–300 mm. Hardened carbide (HM) measuring faces are standard to prevent wear and maintain accuracy over time. Digital variants offer easy reading, unit switching (mm/inch) and data output via USB, RS interface or Bluetooth; advanced models with an integrated minicomputer support Go/NoGo checks, temperature compensation and wireless transmission up to 50 m.
Practical benefits that improve shop‑floor performance
- Reduced rework and higher first-pass yield thanks to repeatable accuracy and carbide-tipped measuring faces.
- Faster, safer measurement cycles by using the ratchet/coupling to limit measuring force to 5 N to 10 N, protecting both part and instrument.
- Flexible inspection workflows with analogue, digital and minicomputer options, including wireless data transfer and mm/inch toggle.
- Versatile coverage with outside, internal, depth and built-in micrometers offering measuring ranges from a few millimetres up to 300 mm and resolution down to 2 µm (internal) or 0.003 mm (standard depth micrometers).
- Durable operation in workshop environments: mechanical models resist dust and moisture, while digital versions are available with IP54 protection.

FAQ
How precise are micrometers for internal measurements?
Internal micrometers in the micrometers category can achieve accuracies around 2 µm when correctly used; digital and minicomputer models improve readout convenience and data integration for traceable inspection results.
When is a digital micrometer preferable to an analogue one?
Choose a digital micrometer when easy readout, unit conversion (mm/inch), or data transmission is required. Digital models with IP54 rating also offer dust and splash protection, while analogue micrometers remain the most robust option in harsh environments.
What measuring force should be used to ensure consistent results?
The recommended measuring force for micrometers is 5 N to 10 N. Use the ratchet or friction thimble to apply this consistent force and rely on the insulating sleeve to minimise heat transfer from the hand.
Can depth micrometers measure small bores and tight features?
Yes. Depth micrometers use a fine needle or flat measuring face and, with suitable extensions, cover narrow or deep features; standard depth micrometers typically span 0–300 mm with accuracies near 0.003 mm, while specialised digital systems offer even higher resolution.
