Gauge pin M323.I79 — 18.79 mm diameter, 50 mm length (Metav IndustryLine)

The gauge pin M323.I79 is a single precision test pin made for workshop metrology tasks, offering a stable reference for end‑measurements, alignment and fit checks in small to medium‑sized assemblies.

• Precision diameter 18.79 mm fit
• Tight tolerance ±0.002 mm
• Special steel construction
• 50 mm length for workshop use

Repeatable fits through controlled diameter and tolerance

A controlled diameter of 18.79 mm combined with a stated tolerance of ±0.002 mm ensures highly repeatable fits when checking hole diameters, locating dowel seats or verifying mating parts. The close tolerance reduces variability in assembly checks and minimises the need for rework. For routine inspection tasks, this level of accuracy provides confidence that measured clearances and interference fits reflect the component reality rather than measurement scatter.

Robust alloy for everyday workshop handling

Manufactured from special steel, the pin is designed to tolerate frequent use in workshop environments without rapid wear. The choice of material provides an advantageous balance between surface hardness and toughness, which benefits longevity when the pin is used in fixture setups, gauging rigs or manual verification operations. At an overall length of 50 mm and a mass of 0.15 kg, the component remains easy to handle while delivering the rigidity required for consistent contact in inspection sequences.

Integrates smoothly with standard inspection procedures

As a precision test pin, this component slots into existing metrology workflows — from simple go/no‑go checks to documented inspection steps in quality control. The form factor supports secure seating in gauge blocks, holders or bespoke fixtures used for end‑measurement and alignment. Because the dimensioning is exact, the pin serves as a reliable reference for process stability and for validating tooling that relies on tightly defined plug diameters.

Practical care to preserve accuracy

To maintain the specified ±0.002 mm performance, routine care is recommended: keep the contact surfaces clean, protect the shaft from knocks, and store the pin in a dry environment to prevent surface corrosion. Occasional inspection for wear and a controlled handling procedure will extend service life and preserve measurement integrity. Where traceable documentation is required, consult Metav Werkzeuge about available calibration options and traceability practices.

FAQ

What is the indicated tolerance and what does it mean in practice?
The stated tolerance of ±0.002 mm means the diameter of the gauge pin is held within two micrometres of the nominal 18.79 mm, providing a tight reference suitable for precision fit and inspection tasks with low variability.

Can the pin be used for mounting and locating components in fixtures?
Yes. The design and special steel construction make the pin suitable for locating, alignment and fixture tasks where a stable, precise plug diameter is required.

Is the pin supplied as a single item or as part of a set?
This entry describes a single gauge pin; the SKU M323.I79 identifies the individual component supplied on its own for bespoke or replacement use.

How should the gauge pin be maintained to preserve accuracy?
Keep the shaft clean and dry, avoid impacts and store in protective packaging when not in use; regular visual checks for wear are recommended to ensure ongoing measurement reliability.

Which applications are typical for this type of gauge pin?
Typical uses include end‑measurement checks, hole gauging, alignment of mating parts and use as a reference in manual or semi‑automatic inspection processes.
