Outside Micrometers – Precision External Measurement Tools

Outside micrometers are high-precision measuring instruments designed to measure the external dimensions of objects such as shafts, wires, and other cylindrical parts. These tools are widely used in quality control and machining applications, where accuracy is crucial for manufacturing components to exact specifications.

Outside micrometers feature a calibrated screw mechanism to ensure precision, offering reliable measurements for objects with diameters ranging from small to large. Available in both mechanical and digital models, these tools are essential for achieving high levels of accuracy in various industrial and technical settings.

Key Features of Outside Micrometers

Micrometer Screw Mechanism

Smooth and consistent operation for precise readings.

Digital & Mechanical Options

Choose from digital or mechanical models based on preference.

Applications of Outside Micrometers

  • Precision Machining: Measuring shafts, rods, and external diameters of mechanical parts.
  • Quality Assurance Labs: Verifying external dimensions within tolerance levels.
  • Automotive Industry: Measuring pistons, axles, and engine components.
  • Tool Rooms & Workshops: Ensuring dimensional accuracy of manufactured parts.
  • Aerospace Sector: Inspecting turbine blades and bearings with tight tolerances.

How to Use Outside Micrometers

  1. Proper Storage: Keep the micrometer clean and stored in its case to avoid damage and environmental effects.
  2. Zero Calibration: Use a standard setting ring or master gauge to calibrate before use.
  3. Position the Micrometer: Gently place it around the object ensuring correct alignment.
  4. Take the Measurement: Rotate the thimble slowly for a precise reading.
  5. Record the Measurement: Read from the scale or digital screen and document the result.
