Mitutoyo 103-930 Outside Micrometer Set 4 Pc 0-4 in

Product Description

The MITUTOYO 103-930 is a 4-piece mechanical outside micrometer set covering a measurement range of 0 to 4 inches in 1-inch increments. Each micrometer features a ratchet stop thimble for consistent measuring force and solid carbide measuring faces for long-term wear resistance. Accuracy is rated at 0.001 inches over the 0 to 3 inch range and 0.00015 inches over the 3 to 4 inch range. The baked enamel finish resists corrosion in shop environments. This set is suited for machinists, toolmakers, quality control technicians, and precision measurement work in industrial and trade settings.

This set is designed for precision outside diameter and thickness measurement on machined parts, bar stock, fasteners, and similar workpieces. The 4-piece configuration covers 0 to 1 inch, 1 to 2 inches, 2 to 3 inches, and 3 to 4 inches in a single package. Each micrometer ships with a certificate of inspection and a setting standard from 1 inch upward, making the set ready for calibrated use out of the box. Typical applications include incoming inspection, in-process quality checks, and tool room measurement tasks.

Installation Notes

Outside micrometers require no installation but should be zeroed and verified against the included setting standards before use. Calibration should be performed at regular intervals per your facility quality plan. Handle measuring faces with care and store each micrometer in its provided case to protect the spindle and anvil surfaces. Clean measuring faces with a lint-free cloth before use to prevent measurement error.
