Mitutoyo 900322 Test Indicator Clamp Dovetail

Product Description

The MITUTOYO 900322 is a test indicator clamp designed to secure dovetail-style test indicators and holding bars during precision measurement work. This accessory provides a reliable mechanical connection between the indicator and its mounting setup, keeping the gauge stable and correctly positioned throughout a measurement task. It is compatible with both 0.157 inch and 3/8 inch diameter dovetail test indicators and holding bars. Machinists, metrologists, and quality control technicians install this clamp as part of a dial indicator or test indicator setup on a surface plate, magnetic base, or similar fixturing system.

This clamp is used in precision measurement environments including machine shops, tool rooms, and quality inspection stations. It suits applications where a test indicator must be held securely at a fixed position relative to a workpiece or reference surface. The part is sold individually and is appropriate for both bench-top and in-machine gauging setups where dovetail-mount test indicators are the standard.

Key Features

• Accepts both 0.157 inch and 3/8 inch diameter dovetail test indicators and holding bars
• Accessory type: clamp, designed for positive mechanical retention of the indicator shank
• Lightweight at 0.07 pounds, minimizing added mass to the measurement setup
• Sold as a single unit with a minimum order quantity of one

Compatibility

Compatible with 0.157 inch and 3/8 inch diameter dovetail test indicators and holding bars as stated in the product specifications.

Installation Notes

This clamp is typically installed by machinists or metrology technicians as part of a test indicator fixturing assembly. Ensure the indicator shank diameter matches one of the two accepted sizes before mounting. Do not overtighten the clamp, as excessive force can deform the shank or alter indicator positioning. No special tools or trade codes are required for installation, but the overall gauging setup should be verified for stability before measurements are recorded.
