Starrett 52765 Indicator Attachment 657AA Base

Product Description

The STARRETT 52765 is a replacement indicator attachment designed for use with the 657AA Magnetic Base Indicator Holder. 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.

This 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.

Installation Notes

Installation of this indicator attachment should be performed by a qualified machinist or metrology technician familiar with indicator base assemblies. Ensure the magnetic base is powered off and the base is placed on a stable, non-metallic surface before disassembling or replacing the attachment. Use only hand tools appropriate for the fastener type present on the 657AA base assembly. Follow the manufacturer instructions included with the 657AA base when reattaching to avoid misalignment or damage to the indicator mount.
