Mitutoyo 101386 Drop Indicator Shell Contact Point M2.5

Product Description

The MITUTOYO 101386 is a shell-style contact point designed for drop indicators and dial gages. It threads directly onto the indicator spindle using an M2.5 x 0.45 thread and provides a 5 mm diameter measuring face with a 5 mm contact point length. The contact tip is machined from solid carbide, which resists wear during repeated measurement cycles. This part is installed by metrology technicians, quality control personnel, and precision machinists who need a reliable, repeatable contact surface on their indicator setups.

This shell contact point is suited for use on AGD Group 1, 2, 3, and 4 dial gages. It is appropriate for bench setups, surface plate inspection work, and fixture-mounted indicator applications in both shop floor and laboratory environments. The solid carbide construction makes it well suited for high-cycle measurement routines where a standard steel point would wear prematurely.

Key Features

• Shell contact point style for standard drop indicator and dial gage spindles
• Solid carbide tip material for extended wear life in high-cycle applications
• M2.5 x 0.45 thread for direct spindle attachment
• 5 mm contact point diameter and 5 mm contact point length
• Compatible with AGD Group 1, 2, 3, and 4 dial gages
• Suitable for mounting on dial gages used in fixture and surface plate inspection

Compatibility

Designed for use with AGD Group 1, 2, 3, and 4 dial indicators. Fits indicator spindles with an M2.5 x 0.45 thread.

Installation Notes

Installation is performed by a qualified metrology or QC technician. Before replacing a contact point, remove the indicator from any active fixture or gage stand to prevent measurement error or spindle damage. Thread the contact point onto the indicator spindle by hand first, then snug with the appropriate spanner or contact point wrench. Avoid applying side load to the spindle during installation, as this can affect indicator accuracy and bearing life.
