Spi 35922 Test Indicator Stylus for Use with 98-399

Product Description

The SPI 35922 is a replacement stylus accessory designed for use with test indicators in precision measurement applications. The stylus serves as the contact point that transmits surface variation to the indicator mechanism, making it a critical component for accurate readings. Weighing 0.15 pounds, this lightweight stylus is built for use with the SPI 98-399 test indicator. It is suited for installation by machinists, metrology technicians, and quality control professionals working in tool rooms, machine shops, and inspection environments.
