Gauge pin M323.I31 — single gauge pin, Ø 18.31 mm, 50 mm length (Metav IndustryLine)

The gauge pin M323.I31 is a workshop‑grade reference pin for quick bore checks and end‑dimension verification in assembly, inspection and toolmaking environments.

• Workshop‑grade finish
• Diameter 18.31 mm precision
• Tolerance ±0.002 mm
• Delivered in protective case

Consistent reference for fast, reliable bore checks

The M323.I31 serves as a stable reference for go/no‑go checks, seating tests and end‑dimension controls. With a nominal diameter of 18.31 mm and a declared dimensional tolerance of ±0.002 mm, the pin reduces measurement uncertainty and shortens inspection cycles by replacing improvised solutions. The 50 mm length provides sufficient engagement for repeatable contact while remaining easy to handle in jig and fixture operations. The result is a measurable improvement in throughput and fewer reworks.

Robust design to withstand workshop conditions

Engineered as a workshop‑grade tool, the pin is manufactured from special steel chosen for dimensional stability and resisting surface wear during repeated use. The compact mass (approx. 0.15 kg) and solid construction ensure steady seating in bores and minimise vibration during tactile checks. Supplied in a protective case, transport and on‑bench storage are simplified, reducing the risk of damage and preserving the pin’s precision between uses — a practical advantage in busy production areas.

Inventory and traceability support for quality workflows

Identification and ordering are straightforward: the item is listed as SKU M323.I31 with GTIN 4061905070914, easing stock management and procurement. The declared tolerance of ±0.002 mm (2 µm) positions the pin between routine workshop gauges and higher‑precision metrology tools, making it suitable as a reliable go/no‑go reference or as part of a gauge set for production control. Clear labelling and consistent dimensions help integrate the component into existing inspection procedures and documentation.
