Extension 25 mm Ø 15.5 mm (M310.061.2) – Measuring-instrument accessory, Metav IndustryLine

The Extension 25 mm Ø 15.5 mm (M310.061.2) is an accessory designed to extend the measuring reach of rod-style internal measuring sets for confined or recessed bores.

• 25 mm extension length
• Ø 15.5 mm shank for secure fit
• Compatible with models 310.059/60/61/64
• Lightweight at 0.1 kg

Increased reach with unchanged measuring behaviour

The accessory extends the effective measuring range by 25 mm, allowing inspections of deeper bores or recessed features without altering the base measuring principle. By maintaining the original contact geometry and a Ø 15.5 mm shank dimension, the extension is engineered to preserve alignment and repeatability when combined with the matching rod measuring set. This approach reduces the need for makeshift adaptions and shortens set‑up time, delivering a measurable improvement in process efficiency during routine quality checks.

Seamless compatibility for reliable workflows

Designed specifically for the series referenced in the item description, the extension ensures straightforward mechanical compatibility with models 310.059/60/61/64, avoiding additional calibration steps in most workshop environments. The compact form and low mass—approximately 0.1 kg—minimise handling fatigue during repeated use and help maintain the original instrument’s centre of gravity. As a result, inspection cycles remain fast and reproducible, supporting higher throughput in production or maintenance routines.

Practical handling and storage benefits

The simple cylindrical design and industry-standard dimensions make the accessory easy to mount, remove and store alongside other measuring rods. Its modest weight and compact footprint lend themselves to organised tool trays or measurement kits, reducing the space required in a busy inspection bench. Where traceability matters, the clear article reference and GTIN simplify inventory management and ensure the correct accessory is selected for each measuring task.

FAQ

Is this extension compatible with my existing rod internal measuring set?
Compatibility is specified for the models 310.059/60/61/64; the Extension 25 mm Ø 15.5 mm (M310.061.2) is engineered to fit those sets without modification.

Will using the extension require recalibration of the measuring set?
In most standard workshop applications no full recalibration is needed; however, final inspection procedures should confirm repeatability when the Extension 25 mm Ø 15.5 mm (M310.061.2) is fitted.

What is the weight and how does it affect handling?
The accessory weighs approximately 0.1 kg, a low mass that keeps handling comfortable and helps maintain the original instrument balance during repeated measurements.

Can the extension reach deep bores that the base rod cannot?
Yes — the purpose of this extension is to increase effective measuring reach by 25 mm so that recessed or deeper features can be accessed with the existing rod measuring set.
