M323.188 — Gauge pin, 1.88 mm diameter, ±0.001 mm (Metav IndustryLine)

A compact gauge pin for precise end‑measurement and fit verification in workshop and inspection environments

• High-precision diameter 1.88 mm ±0.001
• 50 mm workshop-length for deep checks
• Made from durable special steel
• Supplied in transport case for protection

Repeatable precision for inspection and assembly

The compact inspection pin delivers sub-millimetre repeatability where tight fits and end‑dimensions matter. With a diameter of 1.88 mm and a tolerance of ±0.001 mm, the pin provides a clear numeric basis for go/no‑go assessments and small‑bore verification. Such defined accuracy reduces rework, shortens inspection cycles and improves first‑pass yield in assembly and quality control workflows. The narrow tolerance also simplifies statistical process control by lowering measurement variance and supporting reliable process decisions.

Robust construction for workshop environments

Constructed from special steel in a workshop specification, the pin is designed for repeated handling and insertion tasks without sacrificing form stability. A length of 50 mm provides sufficient engagement for many end‑dimension checks while remaining easy to place by hand or with basic fixtures. The lightweight design (approx. 0.004 kg) minimises handling fatigue during batch inspections. Supplied as a single item and protected in a transport case, the pin arrives ready for immediate use and safe storage between inspection runs.

Seamless integration into quality workflows

The inspection pin fits naturally into existing metrology routines and manual gauges where a reliable reference diameter is required. Marked and traceable by SKU M323.188 and GTIN: 4061905055331, it is straightforward to record in inventory and calibration logs. The compact format supports use in fixtures, tactile checks and comparative measurements, enabling faster decision loops on the shop floor. Confidence in component fit and finish is strengthened by the measurable specification, which also aids documentation and audit trails.
