Test pin M323.181 – single 1.81 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

A Test pin for precise end‑measurement and inspection in workshop metrology, designed as a resilient workshop version for routine gauging tasks

• Workshop‑grade design for daily use
• Diameter 1.81 mm with ±0.001 mm accuracy
• 50 mm hardened special steel shaft
• Supplied in transport box for safe handling

Reduce rework through measurable precision

The M323.181 provides ±0.001 mm tolerance (equivalent to 1 μm) on a slender 1.81 mm diameter shaft, reducing measurement uncertainty in tight fits and fine bores. Such sub‑micron accuracy turns subjective checks into objective results, which speeds up root‑cause analysis and cuts reject rates. The narrow diameter and short 50 mm overall length support repeatable contact with minimal deflection, making the pin suitable for end‑of‑line verification and precision gauging in small assemblies.

Designed for busy workshop conditions

Built as a workshop‑grade tool, the pin balances hardness and toughness by using special steel, offering resistance to wear during frequent use. The robust finish and compact form factor make handling straightforward on the shop floor while preserving the measured tolerance. Supplied in a transport box, the component arrives protected for transfer between workstations or storage, reducing the risk of nicks that would affect accuracy.

Practical integration into inspection workflows

The pin suits use as a reference probe for fixture checks, pin‑gauge complements and end‑measurement routines where a defined cylindrical datum is required. Lightweight at approximately 0.004 kg, the test pin is easy to mount in holders or gauge sets without imposing additional inertia. Clear identification with the M323.181 code and GTIN ensures traceability in tool cabinets and inspection reports, supporting organised quality documentation and batch tracking.
