Starrett 70796 Drop Indicator Contact Point 4-48 Thread

Product Description

The STARRETT 70796 is a drop indicator contact point designed for use with AGD dial indicators in precision measurement applications. This small-form contact point features a 4-48 thread size, a 1/32 inch diameter tip, and a contact point length of 5/8 inch, with an overall length of 1/4 inch. Constructed from steel, it provides the dimensional stability and wear resistance required for repeatable indicator readings. The special form design suits setups where a standard contact point geometry does not provide adequate surface contact or reach. Metrology technicians, machinists, and quality control personnel select this style of contact point when performing surface, runout, or bore measurements with AGD-style dial indicators.

This contact point is suited for bench and floor-level precision inspection tasks in both production and toolroom environments. It mounts directly to AGD dial indicators and is appropriate for applications requiring a fine-tipped point on flat, contoured, or hard-to-reach surfaces. The compact overall length of 1/4 inch keeps the indicator assembly low-profile during fixturing. It is a single-piece replacement item sold individually, making it practical for stocking as a consumable or spare in any precision measurement program.

Key Features

• 4-48 thread size for direct mounting to AGD dial indicators
• 1/32 inch diameter tip for fine-point surface contact
• Contact point length of 5/8 inch provides reach for recessed or contoured surfaces
• Steel construction for wear resistance and dimensional stability
• Special form design suited for applications where standard contact geometry is inadequate
• Overall length of 1/4 inch keeps the assembly compact during fixturing

Compatibility

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

Installation Notes

Installation is performed by a machinist or metrology technician using the appropriate wrench or contact-point tool to thread the point into the indicator spindle. Remove the existing contact point before installing the replacement and avoid over-tightening, which can damage the 4-48 thread on the indicator spindle. Ensure the indicator is removed from any live fixture or powered machine before servicing the contact point.
