Gauge pin M323.081 — 0.81 mm diameter, ±0.001 mm tolerance (Metav IndustryLine)

The gauge pin M323.081 is a precision test pin designed for high‑resolution end‑measurement and reference checking in workshop and laboratory inspection tasks.

• Diameter 0.81 mm with ±0.001 mm tolerance
• 50 mm hardened special steel shaft
• Workshop execution for robust handling
• Single-piece design for reference measurements

Precision that reduces rework and uncertainty

The remarkably tight ±0.001 mm tolerance combined with a nominal 0.81 mm diameter delivers measurement certainty where small deviations matter. As a hardened reference probe, this gauge pin converts fine geometric information into a repeatable datum, reducing inspection-related rework and downtimes. The controlled tolerance supports traceable comparative checks and fits seamlessly into established quality routines, making it an efficient tool for statistical process control and dimensional verification.

Built for durability in workshop conditions

Constructed from special steel and offered in a workshop execution, the pin balances wear resistance with dimensional stability. The 50 mm shaft provides sufficient engagement for many end‑measurement scenarios while remaining compact for tight fixtures. The single, solid design minimises play and thermal distortion; this enhances longevity and preserves the original reference dimensions over repeated cycles, which benefits shops that require dependable, low‑maintenance measurement tools.

Integration into inspection workflows

As a dedicated test pin, the component functions well as a reference element for go/no‑go fixtures, pin gauges, and comparative jigs. Its fine diameter makes it suitable for checking small bores, tolerance gauges and precision assemblies where submicron deviation control is needed. The pin’s mechanical simplicity allows fast handling in optical or tactile setups and complements digital readout systems when paired with suitable holders, helping to maintain throughput without compromising measurement fidelity.

Typical applications and sector fit

The gauge pin is particularly relevant for fine mechanics, valve and injector inspection, mould and toolmaking, and precision component suppliers. Its workshop‑grade construction makes it useful at the shop floor as well as in bench metrology. Metav’s offering combines accessible availability with an industrial‑grade specification, supporting both routine quality checks and critical final inspections in small‑batch or serial production environments.
