Compact extension for fast, repeatable measurements

The short 20 mm length of this gauge extension reduces lever effects and maintains measuring stability when space is limited. As a dedicated gauge extension for dial indicators, the component keeps the measuring axis aligned, which helps to avoid deflection during contact measurement. The result is more consistent readings and fewer repeat checks — a clear efficiency gain for shop-floor inspection routines.

Secure contact through a 4 mm probe for reliable repeatability

A 4 mm probe diameter provides a secure seating in indicator holders and sockets commonly used in metrology setups. The relatively robust probe size balances contact precision with mechanical stability, reducing the risk of bending under light lateral load. For users less familiar with gauge adapters: a probe is the measuring pin that transmits contact force from the measured surface to the indicator mechanism, and maintaining its rigidity is crucial for accurate results.

Simple compatibility and straightforward integration into measurement setups

Designed as an extension piece for dial indicators, the part integrates directly into standard indicator stems and holders. This makes it a practical choice when extending the reach of an indicator without altering the instrument itself. Supplied as a single unit, it is ideal for targeted replacements or one-off adaptations on jigs and fixtures. If further specification checks are required, Metav Werkzeuge provides technical guidance and can confirm fitment for specific indicator models.
