100 mm extension for 310.065, 310.066, 310.067 (Ø 28 mm) – Metav IndustryLine accessory

The 100 mm extension for 310.065, 310.066, 310.067 (Ø 28 mm) is an accessory designed to extend the measuring range of compatible rod internal micrometers, enabling reliable measurements in deeper bores and hard‑to‑reach features.

• 100 mm extension for deeper bore measurements
• 28 mm external diameter for stable seating
• Compatible with 310.065 / 310.066 / 310.067
• Part of the Metav IndustryLine accessory range

Reach deeper bores while retaining measurement certainty

Extending the measuring depth by 100 mm provides a practical solution when standard rods fall short. The extension rod increases the functional reach of rod internal micrometers without altering the measuring head or readout, preserving the original instrument's calibration characteristics. By maintaining a consistent alignment through a 28 mm external diameter seating, the accessory reduces lateral play and helps retain repeatable centreline contact, which is essential for accurate bore measurements in assembly, maintenance and quality control contexts.

Engineered for stable alignment and compatibility

Constructed as a direct accessory for the listed micrometer sets, this extension guarantees mechanical compatibility with the corresponding gauge system. The Ø 28 mm seating diameter provides a robust interface that resists tilting under typical handling, so axial alignment is preserved during insertion and retraction. Compatibility with models 310.065, 310.066 and 310.067 allows integration into existing tool stacks, meaning longer measuring tasks can be completed using familiar metrology workflows without additional converters or adapters.

Designed for workshop resilience and straightforward handling

The extension is built to withstand the demands of industrial use while remaining simple to install and remove. Its solid construction contributes to dependable performance in routine shop measurements, improving process efficiency by avoiding repeated re‑fixturing to access deep features. The modest mass also aids stable handling during manual measurement operations, reducing operator‑induced variability and supporting consistent results across multiple measurements.

Integrates with Metav’s precision ecosystem

As part of the Metav IndustryLine range, the extension is a pragmatic addition for workshops and inspection departments seeking to extend capability with minimal disruption. The accessory complements established measurement sets and supports standardised procedures, which helps maintain traceability and repeatability in production and inspection routines. Where longer reach is required, the extension permits measurement without replacing the principal measuring head, reducing downtime and safeguarding instrument calibration integrity.

FAQ

What measurement extension does this accessory provide?
The extension provides an additional 100 mm measuring reach for compatible rod internal micrometer sets, enabling access to deeper bores and recessed features.

Which instruments is the extension compatible with?
Compatibility is specified for models 310.065, 310.066 and 310.067; the extension is engineered to mate directly with those rod internal micrometer assemblies.

How does the Ø 28 mm diameter affect measurement stability?
The 28 mm external diameter creates a stable seating interface that reduces lateral play and helps maintain axial alignment, improving repeatability when measuring deep bores.

Is the extension supplied as part of a set or as a single accessory?
The item is supplied as a single accessory unit intended to expand the measuring range of existing rod internal micrometer sets.

Does the accessory alter calibration of the base instrument?
The extension is intended to be used with the existing calibrated measuring head; separate calibration of the combined setup may be considered according to internal quality procedures.
