Mitutoyo 983510 Depth Micrometer Rod 4 to 5 Inches

Product Description

The MITUTOYO 983510 is a replacement depth micrometer rod designed for use with Mitutoyo 130 and 329 series depth micrometers. This rod extends the measurement range of compatible depth mic bases, covering measurements from 4 to 5 inches. The rod has a 4.00 mm diameter and an overall length of 205.90 mm. It is the standard accessory used when a technician needs to reach deeper bores, slots, or stepped features that fall within the 4 to 5 inch measurement range. Machinists, tool and die makers, and precision measurement technicians install and swap these rods as part of routine setup when measuring depth on workpieces that exceed the range of shorter rod sets.

This rod is intended for use with Mitutoyo 130 and 329 series depth micrometers in precision measurement applications. Typical use cases include inspecting bore depths, counterbore depths, slot depths, and shoulder heights in machined components. It is appropriate for both shop floor and quality control environments where accurate depth measurement in the 4 to 5 inch range is required. The rod swaps into the micrometer base without special tooling, making range changes fast during production or inspection work.

Installation Notes

Rod installation and removal should be performed with the micrometer thimble backed off and the base resting on a stable surface. Use the rod wrench or knurled locking nut appropriate to the micrometer model to secure the rod before taking measurements. Handle precision measuring instrument components carefully to avoid nicking or bending the rod, which would affect measurement accuracy. Consult the instrument manual for proper rod seating and locking procedure specific to the depth mic model in use.
