Starrett 70798 Drop Indicator Contact Point 4-48 Agd

Product Description

The STARRETT 70798 is a drop indicator contact point designed for use with AGD dial indicators. It threads in at a 4-48 thread size and features a contact point diameter of 5.16 mm with a contact point length of 7.14 mm (9/32 inch). The overall length is 0.25 inches (6.30 mm). Constructed from steel, this contact point provides a durable, repeatable contact surface for precision measurement work. Machinists, tool-and-die makers, and quality control technicians install these points when setting up or replacing worn tips on dial indicator assemblies.

This contact point is suited for precision measurement applications in machine shops, manufacturing environments, and inspection stations where AGD-group dial indicators are in use. It is a direct replacement or supplemental contact point for technicians who need a standard-geometry steel tip. The 4-48 thread is the common AGD standard, making this a widely applicable replacement tip across a broad range of indicator setups.

Key Features

• 4-48 thread size compatible with AGD dial indicator standards
• Steel construction for durability and consistent contact surface wear
• Contact point diameter of 5.16 mm for standard spherical tip geometry
• Contact point length of 7.14 mm (9/32 inch) for proper indicator reach
• Overall length of 0.25 inches (6.30 mm) for compact fitment
• Sold individually for single-point replacement needs

Compatibility

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

Installation Notes

Installation is performed by machinists or metrology technicians familiar with dial indicator maintenance. Remove the indicator from any active measurement fixture before replacing the contact point. Thread the contact point in by hand first, then snug with the appropriate small wrench or spanner, taking care not to overtighten and damage the 4-48 threads. Verify indicator calibration after contact point replacement before returning the tool to service.
