Mitutoyo 983512 Depth Micrometer Rod 5 to 6 Inches

Product Description

The MITUTOYO 983512 is a depth micrometer extension rod designed for use with Mitutoyo 131 and 329 series depth micrometers. It extends the measuring range to cover depths from 5 to 6 inches, allowing technicians and machinists to reach measurements that the base instrument alone cannot achieve. The rod measures 4.00 millimeters in diameter and has an overall length of 231.30 millimeters. At 0.1 pounds, it is a lightweight accessory that installs quickly and securely into compatible depth micrometer bases. This rod is a direct replacement or supplemental component for any shop or field kit built around the 131 or 329 Mitutoyo platform.

This rod is suited for precision measurement applications in machine shops, manufacturing facilities, maintenance environments, and quality control settings. It is used when measuring the depth of bores, slots, steps, and recesses that fall within the 5 to 6 inch range. The accessory is sold individually, making it practical to replace a single rod without purchasing a full rod set. It is appropriate for use by machinists, metrology technicians, and tool and die professionals who rely on Mitutoyo depth micrometer systems.

Installation Notes

Installation is performed by machinists or metrology technicians familiar with Mitutoyo depth micrometer systems. Before swapping rods, ensure the micrometer is clean and the spindle lock is disengaged. Insert the rod according to the instrument manufacturer's instructions and verify the rod seats fully before taking measurements. Do not force the rod into the base, as improper seating will produce inaccurate readings.
