M323.201 — Gauge pin (single) Ø 2.01 mm, ±0.001 mm, 50 mm, Metav IndustryLine

M323.201 is a single precision gauge pin intended for fine mechanical inspection and end‑dimension checks in workshop and small‑part inspection environments.

• Nominal diameter 2.01 mm
• Tolerance ±0.001 mm
• Length 50 mm
• Special steel workshop finish

Precision where tight fits matter

The M323.201 delivers substantial measurement confidence for micro‑components thanks to a guaranteed dimensional tolerance of ±0.001 mm. Such a narrow allowance is suitable for critical pass/fail checks on mating holes, pin fits and end dimensions where repeatability is paramount. The tight specification reduces rework and helps maintain consistent assembly quality across production batches. By converting nominal diameter and tolerance into predictable inspection outcomes, the pin supports efficient quality control procedures and shortens decision cycles at the inspection bench.

Robust material and handling benefits for daily use

Constructed from special steel, the pin combines wear resistance with dimensional stability under typical workshop conditions. The 50 mm shaft gives enough engagement depth for most small parts while remaining compact for handheld use and fixture mounting; the balanced length reduces bend and ensures reproducible seating during inspection. Where operators perform many repetitive checks, the material choice and the workshop finish minimise surface wear, maintaining the pin’s functional geometry and preserving calibration intervals.

Clear application logic for process reliability

Designed for fine mechanical and end‑mass checks, this single gauge pin is aimed at precision shops, toolmakers and quality laboratories performing small‑part verification. The nominal Ø 2.01 mm corresponds to micro‑component inspection ranges and is especially useful for verifying bore sizes, locating holes and validating pin fits in assemblies. Using a dedicated, single‑diameter gauge pin avoids ambiguity in go/no‑go assessments and simplifies insertion checks during incoming inspection or final quality validation.

Integration into inspection workflows

The pin’s compact geometry and exact tolerance facilitate straightforward use with vises, plug gauges and bench fixtures commonly found in small workshops. Its repeatable performance supports statistical process control by providing consistent reference measurements that feed into capability studies and inspection logs. When recorded in inspection routines, the measured stability from the pin contributes to fewer false rejects and better traceability of dimensional trends in serial production.
