Mitutoyo 131268 Ball Contact Point 4-48 Dial Indicator

Product Description

The MITUTOYO 131268 is a ball-style drop indicator contact point designed for use with dial indicators, Digimatic dial indicators, and linear gages. The contact point features a solid carbide ball tip measuring 0.06 inches in diameter with a 1-inch contact point length. The 4-48 threaded shank provides a secure, standardized connection to compatible indicator bodies. This type of contact point is installed by metrology technicians and precision measurement professionals who need reliable stylus contact geometry for accurate surface or positional readings in quality control and inspection environments.

This contact point is suited for dimensional inspection tasks in manufacturing, machine shop, and quality lab settings. The ball contact geometry is appropriate for measurements on curved surfaces, grooves, and applications where a flat or pointed tip would introduce cosine error or surface damage. Solid carbide construction provides wear resistance under repeated contact cycles. Compatible instrument types include dial indicators, Digimatic dial indicators, and linear gages as specified by the manufacturer.

Key Features

• Solid carbide ball tip for long service life and wear resistance
• 0.06-inch (1.50 mm) ball diameter for precise contact geometry
• 1-inch contact point length for standard reach applications
• 4-48 threaded shank for secure attachment to compatible indicator bodies
• Suitable for dial gages designed for mounting configurations
• Drop indicator style for compatibility with standard replacement applications

Compatibility

Designed for use with dial indicators, Digimatic dial indicators, and linear gages. Replaces or supplements contact points on instruments accepting 4-48 threaded styli.

Installation Notes

Installation is performed by qualified metrology or inspection personnel. Power down or zero out the indicator before removing or installing contact points to avoid false readings. Use appropriate wrenches sized for the contact point shank to avoid damaging the thread or indicator spindle. Do not overtighten, as over-torquing the 4-48 thread can strip the spindle or crack the carbide tip.
