Mitutoyo 201217 Micrometer Rod 3mm Diameter

Product Description

The MITUTOYO 201217 is a replacement rod-type anvil accessory designed for use with micrometers in precision measurement applications. The rod measures 3 millimeters (0.197 inches) in diameter and 25.40 millimeters (1 inch) in overall length. This part is installed when a standard flat anvil is not suited for the measurement task, allowing contact on small bores, tubes, or curved surfaces where a rod anvil provides accurate, repeatable readings. Calibration technicians, machinists, and metrology professionals install this accessory when application-specific anvil geometry is required.

This rod anvil is used in precision measurement environments including machine shops, quality control labs, and toolroom settings. It is suited for applications where a standard flat anvil would not seat properly against the workpiece geometry. The 3mm rod diameter allows stable contact on grooves, tubes, and similar features where precise outside or wall-thickness measurements are needed.

Key Features

• Rod diameter of 3mm (0.197 inches) for contact on curved or narrow surfaces
• Overall length of 25.40mm (1 inch) providing proper reach and seating depth
• Designed as a direct-fit accessory for compatible MITUTOYO micrometers
• Rod-type anvil geometry enables measurement of grooves, tubes, and recessed features
• Sold individually for single-unit replacement or supplemental kit builds

Compatibility

Designed for use with Micrometer instruments as a rod-type anvil accessory. Confirm anvil thread and shank fit against the specific micrometer model before installation.

Installation Notes

Installation is performed by qualified calibration technicians or machinists familiar with micrometer maintenance. Before replacing the anvil rod, ensure the micrometer is clean and free of debris at the anvil seating area. Thread engagement should be firm and even with no cross-threading. After installation, verify zero calibration per the instrument manufacturer's procedure before returning the micrometer to service.
