Mitutoyo 101187 Drop Indicator Shell Contact Point

Product Description

The MITUTOYO 101187 is a drop indicator shell contact point designed for use with dial indicator gauges in precision measurement applications. The contact point features a solid carbide construction for long service life and consistent contact geometry. It uses a 4-48 thread for secure attachment to compatible indicator spindles. The measurement tip diameter is 0.1969 inches and the contact point length is 1 inch. Licensed metrology technicians, machine tool operators, and quality control professionals install this type of contact point as part of routine gauge setup and maintenance.

This contact point is suited for dimensional inspection setups in manufacturing, machining, and quality assurance environments. It threads directly onto drop-style dial indicator spindles and is appropriate for bench inspection, surface plate work, and fixture-mounted measurement applications. The solid carbide tip resists wear on hardened surfaces and abrasive workpieces, making it well suited for high-cycle inspection routines.

Key Features

• Solid carbide point material for extended wear resistance
• 4-48 thread size for standard dial indicator spindle attachment
• Contact point length of 1 inch for reach in recessed or offset measurement positions
• Tip diameter of 0.1969 inches for defined contact area
• Shell-style contact point design compatible with AGD-standard dial indicators

Compatibility

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

Installation Notes

Installation is performed by metrology technicians or qualified inspection personnel. Zero the indicator and remove any gauge load before replacing the contact point. Thread the contact point onto the spindle stem by hand until snug, taking care not to cross-thread or overtighten, as the 4-48 thread is fine-pitch. Verify seating and re-zero the indicator on a known reference surface before returning the gauge to service.
