Pin Gauge M323.181 — 1.81 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

The Pin Gauge M323.181 is a single, workshop‑grade measuring pin designed for precise end‑dimension and fit verification in production control and inspection tasks.

• ±0.001 mm tolerance for micrometre accuracy
• 1.81 mm nominal diameter for tight fits
• 50 mm hardened special‑steel length
• Workshop‑grade, single‑piece design

Precise performance for reliable inspection results

Built for demanding measurement routines, this gauge pin delivers ±0.001 mm accuracy, which corresponds to a 1 micrometre resolution suitable for high‑precision checks. That level of control minimises uncertainty in go/no‑go assessments and reduces the risk of costly rework. The 1.81 mm nominal diameter is produced with tight manufacturing control to ensure consistent contact geometry; the result is repeatable insertion behaviour and clear acceptance thresholds in production or laboratory environments.

Robust design for frequent handling and longevity

The shaft is made from special steel, heat treated and finished to withstand workshop use while maintaining surface integrity. A 50 mm overall length provides a secure envelope for gripping and positioning during manual inspections and gauge blocks setups, improving handling stability. The single‑piece, workshop execution prioritises practical durability over unnecessary complexity, so measurement throughput remains high even under continuous use.

Practical applications and process benefits

Ideal for end‑dimension checks, pin verification, jig inspection and tight‑fit testing, this measuring pin integrates into standard inspection workflows with minimal adaptation. Using a defined gauge like this reduces inspection time and supports clearer acceptance criteria during quality control. The compact mass and straightforward geometry also make it suitable as a reference pin in assembly fixtures or for quick comparative tests on the shop floor.
