Mitutoyo 303613 Drop Indicator Replacement Rod 0.2 in

Product Description

The MITUTOYO 303613 is a replacement rod designed for use with compatible Mitutoyo drop indicators. Drop indicator rods are precision-machined contact components that transmit linear displacement from the measured surface to the indicator mechanism. This rod measures 0.2 inches in diameter with a 30mm rod diameter specification, making it a direct-fit service part for indicators requiring this size. Installation is straightforward for metrology technicians and machine shop professionals performing routine maintenance or repair on drop-style dial indicators.

This replacement rod is suited for dimensional measurement applications in manufacturing, machine shops, and quality control environments. Drop indicators are commonly used for checking runout, flatness, and surface variation on machined parts. Replacing a worn or damaged contact rod restores the instrument to proper operating condition and maintains measurement accuracy. This part ships as a single unit and is intended as a one-for-one replacement in the supported indicator body.

Key Features

• Rod diameter of 0.2 inches for precise fitment in compatible drop indicator bodies
• 30mm rod diameter specification for metric-dimensioned applications
• Single-unit packaging for individual repair or maintenance jobs
• OEM replacement part from Mitutoyo, a recognized precision measurement manufacturer

Compatibility

Designed as an OEM-style replacement rod for Mitutoyo drop indicators requiring a 0.2-inch diameter contact rod. Consult the specific indicator model documentation to confirm fitment before installation.

Installation Notes

Replacement of drop indicator contact rods should be performed by a qualified metrology technician or instrument repair professional. Before servicing the indicator, remove it from any active measurement fixture and handle it on a clean, stable work surface to avoid damage to precision components. Use only manufacturer-specified tools when disassembling and reassembling the indicator body. After installation, verify contact travel and zero calibration before returning the instrument to service.
