This component serves as the mechanical interface between the magnetic base and the dial indicator or similar measuring instrument, allowing the indicator to be repositioned, swapped out, or replaced without replacing the entire base assembly. Machinists, tool-and-die technicians, and precision measurement professionals install this attachment as a direct service or replacement part. At 0.063 pounds, the 52765 is a compact, lightweight fitting suited to bench and machine tool environments where precise indicator positioning is required.\u003c\/p\u003e\n\u003cp\u003eThis indicator attachment is intended for use in precision measurement setups commonly found in machine shops, manufacturing facilities, and metrology environments. It pairs directly with the STARRETT 657AA Magnetic Base Indicator Holder, making it the correct service replacement when the original attachment is worn, damaged, or lost. Typical applications include surface plate work, lathe and mill setup, and runout inspection where a secure, repeatable indicator mount is essential.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned as a direct-fit attachment for the STARRETT 657AA Magnetic Base Indicator Holder\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.063 pounds, adding minimal mass to the indicator arm assembly\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement without purchasing a full base assembly\u003c\/li\u003e\n  \u003cli\u003eServes as a precision interface component for dial indicators and comparable instruments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the STARRETT 657AA Magnetic Base Indicator Holder.
