Mitutoyo 101205 Spherical Contact Point 0.5 in Agd

Product Description

The MITUTOYO 101205 is a spherical contact point designed for use with drop indicators in precision measurement applications. Machined from steel, this contact point features a 4-48 thread for secure attachment to compatible dial gauge spindles. The spherical tip measures 0.5 inches in diameter with a contact point length of 0.125 inches, providing a consistent and repeatable contact surface during measurement. It is a direct replacement or supplemental contact point for technicians performing close-tolerance inspection work on machined parts, fixtures, and assemblies. Machinists, quality control technicians, and metrology professionals install this type of contact point as part of routine gauge maintenance or measurement setup.

This contact point is suited for use in manufacturing environments, machine shops, and quality inspection stations where AGD-standard dial indicators are in regular use. It is appropriate for both production floor and bench-top measurement tasks where surface contact geometry affects reading accuracy. The compact length makes it a practical choice for confined measurement zones.

Key Features

• Spherical tip geometry provides consistent point contact on flat and curved surfaces
• Steel construction for durability under repeated measurement cycles
• 4-48 threaded shank for compatibility with AGD-standard dial indicator spindles
• 0.5 inches tip diameter with 0.125 inches contact point length
• Sold individually, suitable for single-point replacement or spare inventory

Compatibility

Compatible with AGD Group 1, 2, 3, and 4 dial indicators that accept a 4-48 threaded contact point.

Installation Notes

Installation is performed by metrology technicians or machinists as part of dial indicator maintenance or measurement setup. Remove the existing contact point by unthreading it from the indicator spindle before installing the replacement. Thread the 101205 into the spindle by hand first, then snug with a wrench only to the degree needed to prevent rotation during use — avoid overtightening, which can damage the spindle threads. Verify indicator zero after installing any new contact point.
