Starrett 52939 Universal Shank Dial Test Indicator

Product Description

The STARRETT 52939 is a universal shank accessory designed for use with 711 Last Word dial test indicators. The shank provides a secure, standardized mounting interface that allows the indicator to be held in a wide variety of fixture holders, magnetic bases, and surface gauge arms. With a shank length of 0.5 inches, it is a compact component suited for close-tolerance measurement setups. Machinists, tool-and-die technicians, and quality control professionals install this shank when setting up indicators on production equipment, surface plates, or machine tool spindles.

This accessory is used in precision measurement applications where a dial test indicator must be rigidly mounted to a holding device. Typical scenarios include runout checks, part alignment, and machine tool setup in both job shop and production environments. The universal shank format broadens the range of compatible indicator holders and arm clamps that can be used with the 711 series indicator.

Installation Notes

This shank is installed by machinists and metrology technicians using standard indicator-mounting hardware. Before installing or removing the shank, ensure the indicator and any associated machine or fixture is stationary and secured. Use appropriately sized clamping hardware to avoid deforming the shank. Follow your shop's standard measurement setup procedures and handle precision indicator components with care to maintain calibration integrity.
