Spi 20-595-5 Test Indicator Ball Contact Point Steel

Product Description

The SPI 20-595-5 is a steel ball contact point designed for use with dial test indicators in precision measurement applications. The ball tip measures 0.078 inches (2.00 mm) in diameter, providing a consistent, low-contact-force touch point that reduces measurement error on curved or irregular surfaces. At 0.1 pounds, this is a lightweight replacement or spare contact point intended for machinists, quality control technicians, and metrology professionals who require reliable stylus contact during inspection work. The steel construction offers durability and resistance to wear under repeated use in shop environments.

This contact point is suited for precision measurement tasks in machine shops, tool rooms, and quality assurance settings. It threads into compatible dial test indicators to replace worn or damaged tips, restoring accurate stylus contact without requiring a full indicator replacement. It is designed for use with Peacock test indicators and is appropriate for both bench inspection and on-machine probing setups where a ball-style contact is preferred over a flat or pointed tip.

Key Features

• Ball tip diameter of 0.078 inches (2.00 mm) for consistent contact on curved and contoured surfaces
• Steel construction for wear resistance and long service life
• Lightweight at 0.1 pounds — no added mass to affect indicator performance
• Compatible with Peacock test indicators as a direct replacement contact point
• Ball-style tip reduces sensitivity to surface angle variation during measurement

Compatibility

Designed for use with Peacock test indicators as a replacement or spare ball contact point.

Installation Notes

Contact point replacement is typically performed by a machinist or metrology technician using standard hand tools. Before swapping the contact point, remove the indicator from any active measuring setup to avoid damage to the spindle or tip. Thread the contact point in carefully to avoid cross-threading, and verify zero-reference calibration after installation before returning the indicator to service.
