Spi 107323-SHORT Test Indicator Stylus

Product Description

The SPI 107323-SHORT is a replacement stylus designed for use with SPI alignment and positioning indicators. The stylus is the contact point component that transfers surface variation to the indicator mechanism, making it a critical part of accurate measurement work. This part is used in precision metrology and inspection tasks where maintaining consistent contact geometry is essential. It is installed and serviced by machinists, quality control technicians, and tool-and-die professionals working in manufacturing, fabrication, and inspection environments. The 107323-SHORT weighs 0.5 pounds and ships as a single-piece package.

This stylus is intended for use with SPI dial test indicators in alignment and positioning applications. Typical use cases include runout checks, surface alignment verification, bore centering, and fixture positioning on machine tools. The short-length configuration suits confined inspection setups where clearance around the workpiece or fixture is limited. It is a direct accessory replacement for worn or damaged styli and does not require special tooling to swap out during routine maintenance of the indicator.

Key Features

• Designed as a direct-fit stylus replacement for SPI 13-156-6 and 14-476-63D indicators
• Short-length configuration suited for restricted-access measurement setups
• Sold as a single unit, allowing individual replacement without buying a full kit
• Restores contact-point geometry for accurate surface and alignment readings

Compatibility

Designed for use with SPI 13-156-6 and 14-476-63D alignment and positioning indicators.

Installation Notes

Stylus replacement on dial test indicators is performed by machinists or metrology technicians using the appropriate stylus wrench or pin spanner — do not use pliers or open-jaw tools that could damage the indicator stem threads. Remove the indicator from any live fixture or machine spindle before replacing the stylus. Verify thread engagement is secure but do not overtighten, as indicator contact tips use fine threads that are susceptible to damage. After installation, re-zero the indicator and confirm proper needle response before returning the tool to service.
