Metav IndustryLine extension for dial gauges — 85 mm, M2.5 thread, Ø 4.5 mm

The Metav IndustryLine extension for dial gauges is a compact stainless steel rod that increases probe reach for precise measurements in confined spaces, suitable for workshop inspection and assembly operations.

• Stainless steel construction
• 85 mm extension length
• Thread M2.5 for standard dial gauges
• Ø 4.5 mm probe diameter

Extend measurement reach without losing accuracy

The primary benefit of an extension rod is increased accessibility: the 85 mm length lets inspection points inside housings or recessed features be reached while maintaining a consistent contact geometry. Manufactured from stainless steel, the rod preserves stiffness over its length and reduces flex that would otherwise introduce measurement error. For shops that must measure inside bores, between flanges or within assembled components, this accessory converts a standard dial gauge into a more versatile inspection tool without altering the indicator's calibration chain.

Durable material for repeated workshop use

Constructed in stainless steel, the extension offers corrosion resistance and dimensional stability under routine handling and exposure to workshop environments. The passive corrosion protection reduces the need for frequent replacement and helps retain the rod’s precise diameter of Ø 4.5 mm where the probe engages. This reliability translates into less downtime and fewer interruptions in quality checks, supporting continuous production and dependable inspection results.

Secure fit and predictable performance

A defined M2.5 thread provides a standardised mechanical interface to many dial gauges and magnetic holders, delivering a secure connection that minimises play at the probe junction. The controlled fit prevents unwanted movement during measurement and ensures repeatable contact force transmission from the dial gauge stem to the part. This mechanical consistency is particularly important in quality-control routines where small variances can affect pass/fail decisions.

Simple integration into existing setups

As a compact accessory, the extension integrates seamlessly into existing measurement kits and setups. Its lightweight, low-profile design keeps the centre of gravity close to the indicator, avoiding large moments that could tilt the instrument during use. For maintenance technicians and quality engineers who require quick adaptation to varied inspection tasks, this rod is a pragmatic addition that broadens the capability of standard dial gauges without additional training.

FAQ

What is the primary use of this extension?
The extension is intended to increase probe reach for dial gauges, enabling measurements in recessed or confined areas while maintaining repeatability.

Which dial gauges are compatible with the rod?
Compatibility is determined by the M2.5 thread interface; many standard dial gauges accept this thread, and the accessory is part of the Metav IndustryLine range, SKU M208.063.H.

Is the extension resistant to workshop corrosion?
Yes, the rod is made from stainless steel, offering corrosion resistance suitable for routine workshop environments.

Does the extension affect measurement accuracy?
When used with a securely fitted dial gauge via the M2.5 thread, the rod provides predictable mechanical behaviour and helps preserve the indicator's accuracy by reducing flex and play.
