Inspection Pin M323.653 — Single 6.53 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The Inspection Pin M323.653 is a single test pin designed for precision end‑measurements and gauge checking in workshop and production environments.

• ±0.001 mm tolerance for high precision
• 6.53 mm diameter for tight fits
• 50 mm length in hardened special steel
• Delivered in a protective transport case

Ensuring measurement conformity with micrometre‑grade tolerance

High repeatability is central to efficient quality control: the pin’s ±0.001 mm tolerance minimises measurement uncertainty and supports reliable go/no‑go and end‑dimension checks. When used in plug gauges, fixture probes or bespoke test rigs, the finely controlled diameter ensures consistent contact conditions and reduces the need for rework. This measurable precision translates into shorter inspection cycles and fewer false rejects, improving throughput in serial testing and small‑batch verification alike.

Robust construction for everyday workshop use

Manufactured from special steel and finished for workshop applications, the test pin resists wear under frequent contact and retains dimensional stability over time. A 50 mm shank gives enough engagement for secure seating in holders while remaining compact for tight assemblies; the low mass assists handling and positioning in dense fixtures. Supplied in a protective case, the single‑piece configuration is geared to safe transport and storage, keeping the working surface pristine until installation and prolonging service life.

Practical compatibility and application benefits

Designed as a precise end‑measurement tool, the pin suits gauge building, fixture probing and component verification where small diameters matter. The specified diameter of 6.53 mm is appropriate for tight‑tolerance fits and verification of mating bores; the single‑piece format simplifies integration into modular measuring systems and gauge blocks. Traceable labelling and stable geometry support repeatable setup, while the workshop‑oriented finish eases cleaning and inspection between measurement runs, promoting consistent quality across production batches.

FAQ

What is the declared tolerance of the inspection pin?
The inspection pin M323.653 is manufactured to a declared tolerance of ±0.001 mm, making it suitable for high‑precision end‑dimension checks.

Which materials is the pin suitable for checking?
The M323.653 inspection pin is a dimensional reference tool and can be used to verify bores and fits in components made from typical workshop materials; compatibility with specific component materials depends on the measuring setup and fixturing.

Is the pin delivered ready for use or does it require preparation?
The pin is supplied as a single, finished test pin in a protective case and is ready for installation into gauges or holders without additional machining.

Can the inspection pin be integrated into modular gauge systems?
Yes; the 50 mm shank and compact diameter allow integration into modular fixtures and plug‑gauge assemblies where tight diameter control is required.

Does the product include transport protection?
Delivery of the M323.653 includes a protective case, which preserves the measuring surface and facilitates secure handling during transport.
