Starrett 70795 Drop Indicator Special Contact Point

Product Description

The STARRETT 70795 is a special contact point designed for use with AGD dial indicators in precision measurement applications. This steel contact point features a 4-48 thread size, a 1/16 inch diameter tip, and an overall length of 0.25 inches, making it suited for tight-clearance inspection work where a standard point would not reach or seat correctly. Metrology technicians, machinists, and quality control professionals install this type of contact point when setting up indicator rigs on fixtures, surface plates, or machine tool setups requiring precise, repeatable surface contact.

This contact point is intended for use with AGD (American Gage Design) dial indicators that accept a 4-48 threaded contact point. It is appropriate for both shop-floor and lab environments where fine measurement tolerances are required. The small tip diameter of 1/16 inch allows contact in grooves, bores, and other confined geometry that a larger ball-end point cannot access reliably.

Key Features

• 4-48 thread size for direct installation on AGD dial indicator stems
• 1/16 inch tip diameter for access in confined measurement locations
• 0.25 inch overall length suitable for close-clearance setups
• Steel construction for durability and consistent contact geometry
• Special contact point style for applications where standard points are not appropriate

Compatibility

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

Installation Notes

Contact point replacement requires no special tooling beyond a small wrench or contact point tool to engage the 4-48 thread without damaging the indicator spindle. Always ensure the indicator is removed from active measurement load before swapping contact points. Thread the contact point in by hand first to avoid cross-threading, then snug with a tool only enough to seat securely. Verify runout and seating after installation before resuming measurement work.
