Test pin M323.C78 — Gauge pin, Ø 12.78 mm, length 50 mm (Metav IndustryLine)

The Test pin M323.C78 is a precision end‑measurement pin designed for workshop inspection, setting gauges and repeatable reference checks in fine mechanical environments.

• Workshop‑grade construction
• Diameter 12.78 mm precision
• Tolerance ±0.002 mm
• Supplied in protective transport case

Consistent end‑measurement with fine tolerance

A compact reference element for end‑dimension checks, this gauge pin provides ±0.002 mm tolerance, which corresponds to sub‑micron repeatability suitable for demanding workshop quality control. As a single, solid pin it serves as a fixed reference when setting fixtures or checking mating bores, reducing cumulative error in assembly tasks. The clear numerical specification of 12.78 mm diameter and 50 mm length enables straightforward selection and interchange with existing pin sets or gauge blocks.

Durable, workshop‑ready material and handling

Constructed from special steel, the pin withstands daily shop handling while maintaining dimensional stability. The 50 mm shank length balances reach and stiffness for handheld positioning or fitted checks in jigs. Supplied in a protective transport case, the item is designed for safe transit and organised storage on the shop floor, preserving the reference surface between uses. The workshop‑oriented design prioritises robustness without compromising the precision required for repeatable results.

Easy integration into inspection routines

As a compact precision element within the micro range, the pin suits fine mechanical and general machine‑shop contexts where repeatability and ease of use matter. The single‑piece format simplifies inventory management and replacement; clear labelling supports traceability in inspection processes. When paired with calibrated micrometres or bore gauges, the pin functions as a stable reference for setting tools and verifying end dimensions, helping to maintain throughput while meeting inspection tolerances.
