Gauge pin M323.381 – single test pin, 3.81 mm ±0.001 mm (50 mm) by Metav IndustryLine

A single gauge pin M323.381 designed for precision end‑measurement, assembly alignment and go/no‑go checking in workshop and inspection environments.

• Workshop-grade special steel construction
• Diameter 3.81 mm with ±0.001 mm tolerance
• Length 50 mm for end‑measurement tasks
• Single pin for precise assembly control

Consistent measurement performance for inspection tasks

The pin offers a diameter of 3.81 mm with a verified tolerance of ±0.001 mm, delivering the repeatability required for precise fit and clearance checks. As a hardened test pin in workshop execution, it functions as a stable reference for bore gauging and plug‑fit verification; the tight tolerance minimises ambiguity during pass/fail assessments and supports fast decision‑making on the shop floor. The compact 50 mm length balances handling convenience with sufficient engagement for most end‑measurements.

Durable construction that stands up to daily use

Manufactured from special steel, the component is finished to provide consistent contact surfaces and resistance to wear in routine inspection cycles. The workshop specification highlights robustness without sacrificing metrological reliability: the material choice and precise machining reduce surface variation and inhibit deformation under normal handling. For operators, this means fewer replacements, lower measurement drift and dependable behaviour during repeat checks — attributes that sustain throughput in production and maintenance workflows.

Simple traceability and integration into quality routines

The test pin is supplied as a single item and is straightforward to document within existing inventory and QA systems; identification via SKU M323.381 and GTIN 4061905058288 enables clear traceability in inspection records. Used as a reference or alignment pin, it supports standardised procedures, such as gauge comparison and routine visual inspection, and contributes to reproducible measurement chains. Confidence in results improves process stability, reducing rework and supporting consistent product quality across batches.
