M208.168 measuring contact — ruby ball probe with M2.5 thread (Metav IndustryLine)

The M208.168 is a ruby‑ball measuring contact designed for dial indicators with an M2.5 connection thread, providing a hard, wear‑resistant probing surface for reliable comparative and workshop measurements.

• Ruby measuring contact for dial indicators
• M2.5 threaded connection for standard probes
• Durable ruby ball contact for repeatable readings

Consistent probe performance for everyday metrology

A precision ruby ball contact ensures long service life and stable measurement kinematics, reducing wear-related drift during repeated use. The hard, polished contact surface minimises friction and surface damage on delicate workpieces, which supports repeatable readings on comparative instruments. Built for routine inspection and set‑up tasks, this probe tip contributes to faster, more predictable measuring cycles in quality control and production environments.

Simple compatibility and secure attachment

Connection via a standard M2.5 thread provides universal compatibility with many dial indicators and analogue probes that accept this interface. The threaded mount allows a secure mechanical fit, eliminating play that could introduce measurement error; the compact form factor keeps the centre of gravity close to the indicator body, which helps preserve the instrument’s original measuring behaviour. For retrofitting or replacing worn tips, the accessory offers an economical route to restore probe accuracy.

Practical benefits for workshop and inspection use

The compact contact tip is especially useful where minimal probe footprint is required, such as narrow grooves or small features. The robust ruby contact balances surface hardness with smooth sliding properties, making it suitable for routine contact measurements without marking sensitive finishes. Because the part is a dedicated accessory for dial indicators, it supports quick maintenance and inventory management: small, clearly identifiable spare parts reduce machine downtime.

Proven supply chain and traceability

Supplied as a spare part within the metrology accessory range, this contact is suitable for maintenance stocks and calibration spares. The accessory is identified by SKU and GTIN for straightforward ordering and inventory control, and its lightweight construction reduces shipping and handling constraints for spare‑parts logistics. For users consolidating suppliers, this component integrates into a broader toolkit of workshop measuring aids and replacement items.

FAQ

Is this contact compatible with my dial indicator?
The M208.168 measuring contact fits dial indicators that accept an M2.5 connection thread; confirm the indicator’s connection size before ordering.

What is the contact ball made from?
The probe tip features a ruby ball, chosen for wear resistance and stable sliding characteristics suitable for frequent contact measurements.

How is the contact fitted to an indicator?
The contact is screwed into the indicator’s probe mount via the M2.5 thread and tightened until secure; ensure the mating thread is clean and undamaged.

Will the ruby ball mark delicate surfaces?
Ruby provides a hard, smooth contact; it minimises surface damage compared with rougher materials, but testing on particularly soft finishes is recommended before routine use.

How is the part identified for ordering and stock control?
Order using SKU M208.168 or GTIN 4054469183640 to ensure exact part matching and seamless integration into procurement and inventory systems.
