Starrett 72442 Snug Rod Unit Test Indicators

Product Description

The STARRETT 72442 is a snug rod unit designed as an accessory for dial test indicators. It provides a secure mechanical connection between the indicator and its mounting or holding arrangement, ensuring stable positioning during precision measurement tasks. Weighing 1 pound, this unit is built to integrate directly with compatible Starrett test indicator series, making it a practical replacement or supplemental component for metrology setups on the shop floor or in the field. Machinists, tool and die makers, and quality control technicians are the primary installers and users of this accessory.

The 72442 is used wherever a Series 708, 709, or 811 Starrett test indicator requires a snug rod mounting solution. Typical applications include surface plate inspection work, machine tool setup, and fixture-based measurement on manual or CNC equipment. The snug rod unit holds the indicator firmly at the desired angle or position, reducing measurement error caused by indicator movement or vibration during contact with the workpiece.

Installation Notes

Installation is performed by machinists or metrologists familiar with dial test indicator mounting systems. Before attaching or removing the snug rod unit, ensure the indicator is not under contact load and any associated machine axes are locked or powered down. Use only the appropriate clamping torque for the snug rod to avoid distorting the indicator stem or mounting shank. Follow the indicator manufacturer guidelines for proper assembly to maintain measurement accuracy.
