Take advantage of high‑hardness contact geometry and standardised mounting for fast, repeatable dial‑gauge checks; the compact 2 mm ruby tip and M2.5 thread give reliable service with minimal wear. Order the replacement measuring contact directly via Metav Werkzeuge or ask the consultants for compatibility advice.

Measuring contact "Rubin" — dial indicator contact with 2 mm ruby ball, M2.5 thread

Measuring contact "Rubin" is a compact replacement tip for dial indicators, supplying a hard-wearing contact surface and standard threaded mounting for straightforward installation in workshop and inspection environments.

• Ruby ball tip Ø2 mm
• Thread M2.5 for dial indicators
• Length 20 mm for secure engagement

Precision where it matters: repeatable contact geometry for reliable readings

The ruby ball contact offers a combination of material hardness and polished geometry that reduces surface wear and preserves the contact profile over many measurement cycles. With a 2 mm sphere, the contact area is minimised, which sharpens the touch point and supports consistent readings on small features. Where repeatable measurement is critical, this tip reduces variation caused by wear or deformation and therefore contributes directly to improved measurement repeatability and fewer rework loops.

Simple fitment and serviceability to keep inspection moving

Fitted with a standard M2.5 thread and a 20 mm overall length, the contact mounts into widely used dial gauges and indicator assemblies without adapters. The compact shaft length ensures stable seating in the gauge spindle while offering enough reach for common probe positions. The design supports rapid replacement, limiting downtime in calibration or production checks and making it a pragmatic spare-part for busy metrology benches and shop-floor inspection points.

Built for durability in routine metrology and quality control

The polished ruby contact resists abrasion and maintains surface finish better than many metallic tips, making it suitable for continuous use in quality control, small‑parts inspection and precision assembly tasks. The part’s light mass (approx. 0.1 kg) and standardised thread mean it can be carried as a field spare and fitted quickly during instrument servicing. Supplied as an accessory for dial indicators, the component aligns with workshop practices that prioritise consistent contact behaviour and long service life.

FAQ

How is the measuring contact attached to a dial indicator?
The measuring contact fits via its M2.5 thread; the Measuring contact "Rubin" (Metav IndustryLine, SKU M208.197.1) is screwed into the gauge spindle and tightened to the instrument’s specified mounting torque.

Is the 2 mm ruby ball suitable for small-feature inspection?
Yes — the 2 mm ruby ball on the Metav IndustryLine contact provides a small, defined contact area ideal for measuring tiny radii, bores and fine mechanical parts where a precise touch point is required.

Will the ruby tip resist wear in daily use?
Ruby is highly wear resistant; the polished ruby ball of this contact maintains geometry longer than many metal tips, improving long‑term repeatability for routine inspection tasks.

Can this contact be used with all dial indicators?
Compatibility depends on the indicator’s connection thread; this contact is intended for dial indicators that accept an M2.5 mounting thread. Confirm the instrument’s spindle specification before fitting.

Is the part supplied with any calibration or certificate?
The product is an accessory part; calibration or certificates are not included with this measuring contact unless explicitly stated in the product listing.
