M323.311 inspection pin — 3.11 mm, ±0.001 mm accuracy — Metav IndustryLine

A M323.311 inspection pin engineered for precise end‑measurements and plug‑gauge tasks in workshop metrology, combining compact form with industrial tolerancing.

• Workshop-grade precision inspection pin
• Diameter 3.11 mm with ±0.001 mm tolerance
• 50 mm hardened special steel shaft
• Supplied in protective transport case

Precision designed for repeatable end measurements

This inspection pin delivers consistent results where dimensional certainty matters. The ±0.001 mm tolerance is achieved through controlled machining and finishing, which reduces measurement scatter and lowers the risk of scrap or rework in serial checks. With a nominal diameter of 3.11 mm and a 50 mm usable length, the pin is suitable for tight bores, reference checks and end‑dimension verification in fixtures. The combination of small diameter and high tolerance makes this component ideal where compactness and exact fit are required; the gauge geometry provides predictable contact conditions and therefore repeatable readings across multiple cycles.

Built to withstand workshop conditions

Manufactured in special steel, the shaft is specified for workshop durability without compromising dimensional stability. The workshop‑grade execution means the component toleratesRoutine handling and fixture use while maintaining the machined datum. To protect the surface and preserve accuracy during transport, the pin is supplied in a protective transport case, reducing the likelihood of nicks or contamination before assembly into gauges or test rigs. The light weight and compact form factor make handling effortless while retaining the stiffness necessary for accurate contact in plug‑type applications.

Integrates easily into inspection workflows

Designed for straightforward use in routine inspection and gauge assemblies, the pin supports efficient process checks and quick verification steps on the shopfloor. Its single‑piece delivery simplifies inventory and traceability; the compact diameter is suitable for tight‑access measurement tasks and fits common fixture layouts for end measurements. Combining precise tolerancing with robust material choice supports longer service intervals and predictable measurement behaviour, helping to streamline quality‑control routines and maintain production throughput with fewer interruptions.
