Mitutoyo 983502 Depth Micrometer Rod 0-1 Inch

Product Description

The MITUTOYO 983502 is a replacement depth micrometer rod designed for use with Mitutoyo 134 and 329 series depth micrometers. This accessory rod extends the measurement capability of compatible depth mic sets and is built to maintain the tight tolerances required for accurate depth measurement in precision machining and inspection work. The rod measures 0 to 1 inch in range, has a rod diameter of 4.00 millimeters, and an overall length of 104.30 millimeters. Machinists, tool and die makers, and quality control technicians are the primary users of this component.

This depth rod is suited for shop-floor and inspection-room environments where precise depth measurements are taken on bores, slots, steps, and recesses. It is used as a direct replacement or supplementary rod when expanding a depth micrometer set to cover different measurement ranges. The 0 to 1 inch range makes it appropriate for shallow-depth applications common in precision part inspection and production machining operations.

Key Features

• Measurement range of 0 to 1 inch for shallow-depth applications
• Rod diameter of 4.00 millimeters for compatibility with Mitutoyo 134 and 329 depth micrometers
• Overall length of 104.30 millimeters for proper fit and reach within the micrometer body
• Designed as a direct OEM-style replacement or range-extension rod
• Sold individually — minimum order quantity of 1

Compatibility

Designed for use with Mitutoyo 134 and 329 series depth micrometers as stated by the manufacturer.

Installation Notes

Installation is performed by machinists or metrology technicians familiar with depth micrometer assembly. Before swapping rods, ensure the micrometer is clean and free of chips or debris that could affect seating. Insert the rod fully and verify it is seated and locked according to the micrometer manufacturer's procedure before taking measurements. Confirm calibration after rod changes when working to tight tolerances.
