Mitutoyo 101188 Flat Contact Point 4-48 Solid Carbide Agd

Product Description

The MITUTOYO 101188 is a flat contact point designed for use with drop-style dial indicators. Machined from solid carbide for wear resistance, this contact point features a 4-48 thread for secure attachment to compatible indicator spindles. The contact face diameter measures 0.5 inches, and the contact point length is 3/8 inches (0.375 inches). Solid carbide construction provides long service life in repetitive measurement applications where surface wear is a concern. This replacement contact point is installed by metrology technicians, machinists, and quality control personnel performing precision dimensional inspection.

The MITUTOYO 101188 is suited for shop floor, inspection room, and toolroom environments where AGD-standard dial indicators are in use. The flat contact point style is commonly selected for measuring flat or large-surface workpieces where a spherical or pointed tip would not provide stable contact. It is compatible with AGD Groups 1, 2, 3, and 4 dial indicators, making it a versatile replacement across a wide range of standard indicator sizes used in manufacturing and quality inspection workflows.

Key Features

• Flat contact face provides stable, consistent contact on flat workpiece surfaces
• Solid carbide construction resists wear during high-cycle measurement tasks
• 4-48 threaded shank for secure attachment to compatible indicator spindles
• Contact point length of 3/8 inches (0.375 inches) suits standard indicator geometries
• Contact face diameter of 0.5 inches for broad surface coverage
• Compatible with AGD 1, 2, 3, and 4 dial indicators

Compatibility

Designed for use with AGD Group 1, 2, 3, and 4 drop-style dial indicators with a 4-48 threaded spindle contact point stem.

Installation Notes

Contact point replacement is performed by machinists and metrology technicians using standard dial indicator servicing procedures. Remove the existing contact point by unthreading it from the indicator spindle before installing the replacement. Take care not to overtighten the contact point, as damage to the 4-48 thread or the indicator spindle may result. Verify indicator calibration after swapping contact points to confirm measurement accuracy.
