Mitutoyo 21BZB005 Drop Indicator Contact Point

Product Description

The MITUTOYO 21BZB005 is a drop indicator contact point designed as a replacement accessory for use with Digimatic and dial indicators. Contact points are the direct-contact components that transfer dimensional measurement from a workpiece surface to the indicator mechanism. This part is installed by machinists, quality control technicians, and metrology professionals performing precision measurement tasks in shop-floor, inspection room, or production line environments. The 21BZB005 ships as a single unit and weighs 0.5 pounds.

This contact point is suited for use in applications requiring repeatable, accurate surface contact during measurement operations. It is commonly installed in setups involving drop indicators mounted on surface plates, magnetic bases, or dedicated fixtures for comparative measurement and part inspection. Professionals replacing worn or damaged contact tips will find this a direct-fit replacement for compatible Digimatic and dial indicator models.
