Spi 20-692-0 Ball Contact Point Carbide Compac Test Indicators

Product Description

The SPI 20-692-0 is a carbide ball contact point designed for use with test indicators in precision measurement applications. The contact point features a 0.078 inch ball diameter and an overall contact point length of 1.292 inches, making it suitable for fine-tolerance dimensional inspection work. Carbide construction provides excellent wear resistance and maintains accuracy through repeated use. This type of contact point is installed and serviced by machinists, quality control technicians, and metrology professionals who require consistent, repeatable measurements in shop or lab environments.

This contact point is intended for use with Compac test indicators. It is commonly used in applications involving surface runout checks, bore alignment, and part inspection on machine tools, surface plates, and inspection fixtures. The compact geometry suits confined measurement areas where a standard contact point would not seat properly, making it a useful addition to a precision measurement toolkit in manufacturing and inspection settings.

Installation Notes

Contact point replacement on test indicators should be performed by a qualified metrology technician or machinist familiar with indicator maintenance. Before replacing the contact point, remove the indicator from any active fixturing and ensure it is not under spring load. Use the appropriate driver or wrench to avoid damaging the indicator spindle threads. After installation, verify indicator zero and repeatability before returning the instrument to service.
