M323.410 – Gauge pin Ø 4.10 mm, ±0.001 mm (Metav IndustryLine)

M323.410 is a single test pin designed for precise end-measurements and dimensional checks in workshop inspection and fixture set-up.

• High-precision ±0.001 mm tolerance
• Diameter 4.10 mm, length 50 mm
• Workshop-grade special steel construction

Micrometric certainty where it matters most

The M323.410 gauge pin delivers a nominal tolerance of ±0.001 mm, equivalent to one micrometre, which places it among tools suited to the tightest shop-floor and inspection tasks. This level of precision reduces measurement uncertainty and helps identify marginal fits early in the process, decreasing rework and scrap rates. The controlled diameter of Ø 4.10 mm provides a stable reference for bore checking and plug-fit verification; the small nominal variation ensures consistent results when used for pass/fail assessments or as a reference in comparative gauging. Explaining the figure: a tolerance of ±0.001 mm means the pin’s diameter remains within one micrometre of its nominal value, so measurements made against it are highly repeatable and reliable for quality-critical components.

Built to withstand workshop use with sensible handling

The test pin is finished in special steel chosen for dimensional stability and resistance to everyday workshop conditions. The workshop version construction is intended for routine inspection and fixturing tasks, balancing hardness with machinability to avoid surface damage during handling. At 50 mm length, the pin offers sufficient engagement depth for many standard bores while remaining compact and easy to position. The single‑item supply simplifies stock-keeping when pins are kept as spares for calibrated sets or used individually for end-measurement verification. The robust material choice and plain but practical finish minimise the need for frequent replacement and support sustained use in production environments.

Practical benefits for inspection, set-up and quality assurance

In practice, this gauge pin is used for end‑measurements, plug checks and to establish reference points during assembly or machining set-up. As a compact, precise datum, the pin speeds routine checks and helps maintain process stability when used alongside digital or analogue measuring systems. The modest weight and compact form factor facilitate manual handling and quick interchange on a measuring bench or in a fixture. When combined with clear process instructions and consistent handling, the result is shorter inspection cycles and fewer ambiguous readings. For laboratories and workshops seeking dependable micrometric checks without complex setup, the pin delivers straightforward applicability and measurably improved control over critical fits.
