Starrett 70792 Drop Indicator Contact Point Agd Dial

Product Description

The STARRETT 70792 is a drop indicator contact point designed for use with AGD dial indicators in precision measurement applications. The contact point features a 4-48 thread size, a 0.5 inch diameter, and a contact point length of 0.125 inches, with an overall length of 0.25 inches. Constructed from steel, this contact point delivers consistent, repeatable surface contact for accurate indicator readings. It is a direct-replacement accessory for technicians and machinists who require reliable contact tips on their dial indicator setups.

This contact point is suited for use in machine shops, metrology labs, and field service environments where AGD-style dial indicators are used for runout checks, surface alignment, bore measurement, and similar precision tasks. Its compact dimensions make it appropriate for tight-clearance measurement scenarios. Installation and replacement are straightforward, requiring only basic hand tools and the correct 4-48 thread engagement.

Key Features

• 4-48 thread size for secure, precise fitment on compatible dial indicator stems
• Steel construction for durability and wear resistance at the contact surface
• 0.125 inch contact point length for low-profile surface contact
• 0.5 inch diameter provides stable contact geometry
• 0.25 inch overall length suits compact indicator tip configurations
• Single-piece packaging with no minimum order requirement beyond one unit

Compatibility

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

Installation Notes

Contact point replacement on dial indicators should be performed by a qualified machinist or metrology technician. Remove the indicator from service before swapping contact points to avoid accidental deflection or damage to the spindle. Use the appropriate small wrench or contact point tool to thread the 70792 into the indicator spindle by hand first, then snug only — do not over-torque the 4-48 thread. Verify indicator zero and calibration after installing any new contact point.
