A precise, easytoread measuring tool for professionals and hobbyists: this Digital Display Outer Diameter Micrometer (Electronic Spiral Micrometer / Thread Wall Thickness Gauge, model G/r/e/en) combines a digital readout with a smooth spiraladjust mechanism to simplify accurate measurements of external diameters and thread wall thickness. Key benefits Clear digital display removes guesswork from readings and speeds up inspection and layout tasks. Spiral (electronic) thimble gives fine, controlled advancement for repeatable contact and stable measurement. Dualpurpose use: designed to measure outer diameters and to act as a thread wall thickness gauge, reducing the need to switch tools. Handheld and portable design lets you measure on the bench or in the field. Main features and attributes Functionality: digital electronic readout for quick numeric readings; spiraldriven spindle for precise adjustment; suitable for outer diameter measurements and thread wall thickness checks. Compatibility: ideal for use on cylindrical parts, rods, shafts, tubes and threaded components where external diameter or wall thickness must be confirmed. Size and handling: compact, handheld form factor for comfortable onehanded operation and easy storage. Construction and durability: engineered for workshop and field use with a stable frame and precision contact surfaces to maintain measurement consistency. Performance: electronic readout reduces reading errors and enables faster inspections compared with analog micrometers; the spiral mechanism improves control for small adjustments. Typical applications Machining and fabrication: check shaft diameters, turned parts and finished components during setup or final inspection. Quality control and inspection: verify outer diameters and thread wall thickness on production samples and incoming materials. Maintenance, plumbing and automotive work: measure pipe or tube wall thickness and threaded fittings to confirm fit and serviceability. How it helps you work faster and with fewer errors Readings are displayed digitally to eliminate parallax and interpretation mistakes common with analog scales. The spiral adjustment produces smooth, repeatable contact with the workpiece, improving consistency between measurements. One tool covers both outer diameter measurement and thread wall thickness checking, simplifying your toolkit. Practical use tips Ensure contact surfaces are clean before measuring for repeatability. Apply consistent pressure when using the spiral thimble to avoid measurement variation. Use in a stable position and avoid tilting the micrometer relative to the workpiece. Suitable users CNC operators, machinists and toolmakers performing dimensional checks. Quality inspectors and lab technicians conducting batch verification. Technicians and mechanics who need portable, reliable diameter and thread wall thickness measurements.
