Starrett 70794 Drop Indicator Contact Point Agd Dial

Product Description

The STARRETT 70794 is a drop indicator contact point designed for use with AGD dial indicators in precision measurement applications. This steel contact point features a 4-48 thread size, a diameter of 5.33 mm (13/64 inch), and an overall length of 6.30 mm (0.25 inch), with a contact point length of 12.70 mm. Its compact form and accurate thread engagement make it a reliable replacement or spare component for technicians and machinists who depend on consistent indicator performance in layout, inspection, and quality control work.

This contact point is suited for use in machine shops, manufacturing environments, and precision inspection setups where AGD-standard dial indicators are in regular use. Technicians performing surface, bore, or runout measurements will find this a direct-fit component for maintaining indicator accuracy. It is sold individually and is appropriate for both bench and field measurement tasks requiring a standardized 4-48 threaded contact point.

Compatibility

Designed for use with AGD dial indicators requiring a 4-48 threaded contact point.

Installation Notes

Installation is performed by machinists or metrology technicians using standard hand tools. Remove the existing contact point by unthreading it from the dial indicator spindle before installing the replacement. Thread the 70794 in by hand until snug, taking care not to overtighten and risk damaging the indicator spindle threads. Ensure the indicator is removed from service and zeroed after contact point replacement to confirm measurement accuracy.
