Starrett 50153 Drop Indicator Point Kit 14 Piece

Product Description

The STARRETT 50153 is a 14-piece drop indicator point kit designed for use with dial drop indicators in precision measurement applications. The kit includes steel ball contact points threaded at 4-48 to ensure a secure, accurate fit on compatible indicator spindles. These replacement and accessory points allow technicians and machinists to adapt their drop indicators to a variety of measurement tasks without swapping full indicator assemblies. At 0.25 pounds, the kit is compact and easy to store in a toolbox or gauge cabinet. It is sold as a single package with a minimum order quantity of one.

This kit is suited for metrology and quality control environments where drop indicators are used to check runout, surface variation, and part alignment. It is commonly used on production floors, in machine shops, and during mechanical inspection work. The steel ball contact points are appropriate for use on flat, curved, and irregular surfaces where a standard flat or pointed contact would not provide repeatable readings. Technicians who regularly use STARRETT 25R Contact Point Sets will find these points directly compatible with that system.

Key Features

• Steel ball construction for durability and consistent surface contact

Compatibility

Designed for use with STARRETT 25R Contact Point Sets. Fits drop indicators with a 4-48 threaded spindle contact point. Verify thread size on your indicator before installation.

Installation Notes

Contact point installation and removal should be performed with the indicator removed from active service to avoid damage to the spindle. Use an appropriate small wrench or contact point tool to thread the point securely onto the 4-48 spindle without overtightening. Inspect threads on both the point and spindle for damage before installation. Handle steel ball points carefully to avoid nicking the contact surface, which can affect measurement accuracy.
