Gauge pin M323.191 — precision test pin, 1.91 mm, ±0.001 mm, 50 mm length

The Gauge pin M323.191 is a compact precision test pin designed for end-measurement and gauging tasks in workshop and inspection environments.

• Workshop version for robust everyday use
• Diameter 1.91 mm for narrow bores
• Tolerance ±0.001 mm for micron precision
• 50 mm length for end-measurement tasks

Micron-level repeatability that protects process quality

A tolerance of ±0.001 mm (one micron) places this gauge pin in the class of precision inspection tools suited to high-accuracy tasks. That numerical tolerance means the pin can be used where repeatable fits and clearances are critical, for example when verifying bore roundness, plug fits or end dimensions on small components. The fine tolerance reduces the risk of rework and helps to maintain consistent assembly quality, so measuring routines become a reliable control point rather than an uncertain step. The M323.191 designation simplifies procurement and traceability in quality documentation.

Slim profile for tight bores and accurate end measurements

With a diameter of 1.91 mm and a length of 50 mm, the pin is tailored for narrow or deep bores where thicker gauges cannot access without disturbance. The slender geometry enables snug fit checks, alignment aids and the transfer of a defined datum in fixtures. The 50 mm working length balances reach with rigidity, keeping deflection low during insertion and withdrawal. In practical terms, that means more consistent gauge readings and fewer measurement artefacts when inspecting small components or precision bores.

Workshop execution and material choice for durability

Manufactured from special steel, this test pin offers dimensional stability and resistance to routine workshop wear. The designation "workshop version" signals a construction that tolerates frequent handling and process use while maintaining the specified accuracy. Simple maintenance—cleaning and gentle protection against corrosive atmospheres—preserves the measurement datum and prolongs service life. The compact mass (lightweight construction) also makes the pin easy to handle during repeated checks or in automated feeding arrangements.

Clear procurement data and integration into inspection routines

Technical identifiers simplify stockkeeping and quality records: the item is listed under SKU M323.191 and can be referenced in inspection plans and procurement lists. The small footprint and defined specification make this pin suitable as a standard inspection tool in toolrooms, assembly benches and first-off checks. Metav IndustryLine supplies the product as part of a broad range of metrology items, backed by the company’s logistics and quality filtering in Emmerich, which supports consistent availability for workshops and production lines.
