Extension for three‑point IMS M312.330 — 101.6 mm length, Ø 5.8 mm (Metav IndustryLine)

The Extension for three‑point IMS M312.330 is an accessory designed to extend the reach of three‑point internal measuring assemblies for small bore measurements across multiple jaw sizes

• Extension for three‑point IMS systems
• Length 101.6 mm for extended reach
• Ø 5.8 mm with M5 thread connection
• Compatible with 6–8 / 8–10 / 10–12 mm jaws

Extend reach without compromising measurement reliability

This compact extension delivers a straightforward way to measure deeper or harder‑to‑access internal features without altering the original measuring head. With a 101.6 mm length and a snug Ø 5.8 mm body, the accessory maintains radial stability while allowing the existing three‑point measuring assembly to work within its intended range. The preserved geometry reduces the risk of misalignment and keeps the effective contact points consistent, which benefits repeatability in routine inspection tasks.

Designed for precise integration with three‑point measuring setups

Connection via the M5 thread ensures a secure and repeatable mount to the measuring head; the mechanical interface is dimensioned for minimal play so that the probe centreline remains stable during insertion and retraction. The extension is compatible with three jaw assemblies sized 6–8, 8–10 and 10–12 mm, enabling a single accessory to support several common internal measuring ranges. This reduces downtime for tool changes and simplifies inventory management in metrology departments.

Practical handling and application in workshop environments

Fitting and removal are deliberately straightforward: the threaded attachment provides a firm coupling without special tools, making the part suitable for frequent use in production and quality‑control contexts. The modest mass keeps the added inertia low, so dynamic measuring procedures or manual probing are less likely to introduce error through increased operator influence. The extension is therefore a pragmatic choice for technicians seeking extended reach with familiar handling characteristics.

Why this accessory makes sense for precision workflows

Integrating this extension into existing three‑point assemblies supports leaner tool sets by adapting one measuring head for multiple bore depths. The combination of defined connection geometry and standardised sizes improves process consistency across shifts and operators. As a Metav IndustryLine accessory, the component aligns with the company’s emphasis on reliable, workshop‑ready measuring solutions aimed at reducing supplier complexity and ensuring steady availability.

FAQ

Is this extension suitable for all three‑point IMS heads?
Compatibility depends on the thread and jaw range; the extension is designed for three‑point assemblies with matching M5 mounting and for jaw sizes 6–8, 8–10 and 10–12 mm as specified for the M312.330 accessory.

Will using the extension affect measurement accuracy?
When correctly mounted, the M312.330 maintains the mechanical geometry of the measuring head; because the connection is threaded and dimensioned for minimal play, measurement repeatability is preserved for standard inspection tasks.

How is the extension attached and removed?
Attachment is via an M5 thread for a secure, repeatable fit; the design allows tool‑free hand mounting in most workshop routines, reducing changeover time between measurements.

Can the same extension be used across multiple bore depths?
Yes. The accessory was conceived to adapt a single three‑point measuring head to deeper or recessed bores, covering the listed jaw ranges without requiring different heads for each depth.

Is spare stock and rapid delivery available from Metav?
Metav IndustryLine maintains a broad supply network from Emmerich; contact Metav Werkzeuge to confirm current availability and lead times for the M312.330 extension.
