Mitutoyo 21JZA210 Depth Gage Base 2.5 in Stainless Steel

Product Description

The MITUTOYO 21JZA210 is a stainless steel depth gage base designed to provide a stable, flat reference platform for Mitutoyo depth gages used in precision measurement applications. Measuring 2.5 inches in length with a 0.375-inch base hole diameter, this base accepts a depth gage rod or blade and holds it perpendicular to the workpiece surface during measurement. The stainless steel construction resists corrosion and wear, making it well suited for shop floor environments where cutting fluids or moisture are present. Machinists, toolmakers, and metrology technicians install and use this accessory as part of a complete depth gaging setup.

This base is intended for use with Mitutoyo digital and dial depth gages in both production and inspection environments. It is compatible with a specific set of Mitutoyo depth gage models and is used wherever precise bore depth, shoulder depth, or step measurements are required. The base sits flat on the reference surface while the gage rod extends into the feature being measured, providing consistent contact and repeatable readings across multiple measurement cycles.

Installation Notes

Installation is performed by metrology technicians or machinists as part of a depth gage assembly. Before assembling or disassembling the base from the gage, ensure the gage is zeroed and the workpiece is secured. Clean the base contact surface before use to prevent debris from affecting measurement accuracy. Follow the gage manufacturer instructions for proper rod insertion and locking procedures.
