Spi Z9611 Test Indicator Holding Bar with Pin

Product Description

The SPI Z9611 is a test indicator holding bar with pin, designed to mount dial test indicators and similar gauging instruments onto height gages and column clamps. The bar measures 3 inches in overall length and is machined to fit clamps that accept a bar profile 3/16 inches wide by 5/16 inches in height. It provides a rigid, repeatable mounting point for test indicators used in layout, inspection, and comparative measurement work. Metrology technicians and machinists install this accessory when setting up height gage-based inspection routines on surface plates.

This holding bar is suited for use in quality control labs, tool rooms, and production floor inspection stations. It integrates with standard height gage column clamp systems that accept the 3/16 inch by 5/16 inch bar profile, making it a common replacement or spare for existing setups. The pin feature secures the test indicator stem, keeping it fixed during measurement passes across a part surface.

Key Features

Compatibility

Designed for use with all height gages and column clamps that accept bars 3/16 inches wide by 5/16 inches in height.

Installation Notes

This accessory is installed by metrology or quality technicians as part of a height gage indicator assembly. Ensure the column clamp is loosened before inserting or removing the bar, and verify the clamp screw is fully tightened before taking measurements to prevent indicator shift. No special tools are required beyond the clamp tightening mechanism native to the height gage.
