Digital Micrometer Screw Gauge

A Digital Micrometer Screw Gauge is a high-precision measuring instrument used to accurately measure the thickness, diameter and external dimensions of metal, plastic, wood, rubber and other solid materials. It is widely used in engineering workshops, automotive garages, manufacturing industries, machine shops, laboratories, quality control departments and technical training institutions.

Unlike a traditional micrometer, a digital micrometer features a large LCD display that provides fast, accurate and easy-to-read measurements. Most models offer measurement in both millimetres (mm) and inches, making them suitable for local and international engineering standards.

Manufactured with a hardened steel frame and precision-ground measuring faces, a digital micrometer screw gauge delivers consistent accuracy for professional inspection and production work.

Quick Specifications

Main Features

High Measurement Accuracy

The digital micrometer provides highly accurate measurements suitable for precision engineering and quality inspection.

Typical applications include measuring:

• Shaft diameters
• Metal sheet thickness
• Bearings
• Wires

• Plastic components

Large LCD Display

The clear digital screen offers:

• Easy reading
• Faster measurements
• Reduced reading errors
• Improved visibility in workshops

Measurements can be displayed instantly without interpreting graduated scales.

Millimetre and Inch Conversion

Most models include a one-button conversion function that allows users to switch between:

• Millimetres (mm)
• Inches (in)

This is useful for engineers working with different measurement standards.

Carbide Measuring Faces

Precision-ground carbide anvils provide:

• Excellent wear resistance
• Long service life
• High measurement stability
• Consistent accuracy

Ratchet Stop Mechanism

The built-in ratchet stop applies a consistent measuring force to help prevent excessive pressure on the workpiece.

Benefits include:

• Repeatable measurements
• Better accuracy
• Reduced user error

Zero Setting Function

The digital display can be reset to zero at any point, making comparative measurements quick and convenient.

Automatic Power Saving

Many digital micrometers feature an automatic shut-off function to extend battery life when the tool is not in use.

Durable Steel Frame

The rigid frame minimises flexing during measurement, helping maintain accuracy over long periods of use.

Frequently Asked Questions

What is a digital micrometer screw gauge used for?

It is used to measure the outside diameter, thickness and width of components with very high precision.

What is the measuring range?

The most common model measures from 0 to 25 mm, although larger ranges such as 25–50 mm, 50–75 mm and 75–100 mm are also available.

How accurate is a digital micrometer?

Most quality digital micrometers provide an accuracy of approximately ±0.002 mm, depending on the manufacturer and model.

Can it measure in inches?

Yes. Most digital micrometers allow instant switching between millimetres and inches.

Does it require batteries?

Yes. Most models use a CR2032 or SR44 button cell battery, depending on the design.

Is it better than a vernier caliper?

For measuring external dimensions with the highest precision, a digital micrometer generally offers finer resolution and greater accuracy than a standard vernier caliper.

How should I store the micrometer?
