Gauge pin M323.351 — 3.51 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

A gauge pin M323.351 designed for precise end‑measurement, fixture alignment and go/no‑go verification in workshop metrology and production inspection

• High‑precision ±0.001 mm tolerance
• Diameter 3.51 mm for tight fits
• 50 mm robust working length
• Workshop version for everyday use

Consistent accuracy for tight tolerance control

The gauge pin delivers ±0.001 mm geometric accuracy, making it suited to applications where repeatable end‑measure verification is required. Its calibrated tolerance ensures that positional checks and plug‑gauge operations produce consistent results, reducing rework and inspection uncertainty. By specifying the measured diameter as 3.51 mm and a working length of 50 mm, the component provides a predictable reference for alignment tasks and pass/fail fixtures, simplifying quality control routines in small‑series production and toolroom environments.

Durable design that supports frequent handling

Manufactured from special steel, this test pin is engineered for durability under regular workshop use. The workshop version construction balances hardness and resistance to surface wear, so contact points retain form across many cycles. For technicians assembling jigs or checking bore fits, the pin’s compact dimensions and modest mass improve manoeuvrability while resisting damage from typical handling. The choice of material and finish reduces the need for frequent replacement, supporting a cost‑effective inspection workflow.

Integration into inspection setups and gauges

As a precision gauge pin, the item fits into common fixture geometries and inspection nests without special adaptors. Its nominal diameter and tight tolerance make it compatible with transfer gauges, plug gauges and alignment pins used in assembly and verification processes. When incorporated into test rigs, the pin acts as a stable reference feature that supports fast go/no‑go decisions, enabling efficient in‑process checks and setup verification that keep production moving and minimise downtime.
