Extension for dial indicators M208.063.8 — 80 mm length, M2.5 thread (Metav IndustryLine)

An extension for dial indicators that increases probe reach for confined and recessed measurement tasks in workshop and inspection environments.

• 80 mm extension length for deeper reaches
• Thread M2.5 for standard dial gauge spindles
• Ø 4.5 mm shank for stable mounting
• Stainless steel for corrosion resistance

Extend reach without compromising accuracy

The compact 80 mm extension provides a simple, reliable way to access recessed bores, stepped surfaces and hard‑to‑reach inspection points while maintaining the original precision of the measuring chain. Fitted with a standard M2.5 thread, the component mates directly with most dial gauge spindles and probe holders, so insertion does not introduce play or significant run‑out. The modest length reduces lever action and bending moment compared with longer adapters, preserving repeatability during repeated checks in production or maintenance routines.

Durable stainless steel for workshop reliability

Manufactured from stainless steel, the extension resists corrosion and abrasion in workshop environments where coolant, oils or humidity can affect lesser materials. The Ø 4.5 mm shank offers a secure seating in collets and holders, reducing micro‑movement that would otherwise compromise readings. As a simple mechanical accessory it requires no calibration itself, yet it contributes to a stable measurement setup: by choosing a corrosion‑resistant alloy and tight thread tolerances, the part helps sustain consistent contact geometry and extends the service life of the gauge assembly.

Easy integration for consistent inspections

Integration into existing inspection fixtures and hand‑held setups is straightforward thanks to the M2.5 interface and industry‑standard dimensions. The extension suits batch inspection, spot checks on assemblies and quality control benches where repeated mounting and dismounting occur; its compact profile minimises interference with surrounding features and tooling. Using a standardised accessory reduces setup time and supports a smoother workflow across different gauges and fixtures, which in turn improves throughput and lowers the risk of measurement errors in routine checks.

FAQ

What instruments is this extension compatible with?
The extension for dial indicators is designed for dial gauges and probe holders with an M2.5 spindle thread and fits standard mountings used in workshop and inspection environments.

Will the extension affect measurement accuracy?
When used with a suitable holder and correctly mounted, the extension maintains measurement reliability; its 80 mm length and robust shank geometry are chosen to minimise additional deflection and preserve precision.

Is the component corrosion resistant?
Yes, the part is manufactured from stainless steel, providing enhanced corrosion resistance and longer service life in typical workshop conditions.

Can the extension be used with digital dial indicators?
The extension is compatible with digital and analogue dial indicators that accept an M2.5 threaded probe; ensure the instrument’s spindle connection matches the M2.5 standard for secure mounting.

Are adapters available for other thread sizes?
The supplied unit has an M2.5 thread; adapters for other thread standards can be sourced separately if an alternative spindle interface is required
