Gauge pin M323.379 — single precision pin, 3.79 mm, ±0.001 mm accuracy

Gauge pin M323.379 is a single, precision ground pin intended for accurate bore checks and end‑measure verification in workshop and small‑component inspection applications.

• ±0.001 mm tolerance for micrometric checks
• 50 mm hardened and ground length
• Workshop design for everyday use
• Special steel construction for wear resistance

Ensure repeatable results with micrometre‑class accuracy

The compact pin offers a verified ±0.001 mm tolerance, which directly reduces measurement uncertainty during end‑dimension checks and plug‑gauging tasks. Such a fine tolerance is classified in the sub‑millimetre metrology segment and supports tight process control, enabling quality teams to detect out‑of‑tolerance bores before assembly. The 3.79 mm diameter is particularly suited to small‑bore inspections where consistent contact geometry and a true‑round shaft are decisive. By relying on a stable reference pin rather than improvised tools, measurement variability and subsequent rework are minimised, improving throughput and part conformity.

Robust workshop construction for routine use

Designed as a workshop version, the pin combines a ground finish with a special steel body to withstand everyday handling without rapid wear. The 50 mm effective length balances accessibility with stiffness so the shaft resists bending during insertion and extraction, preserving the stated tolerance over repeated cycles. A low mass of 0.007 kg keeps handling comfortable, while the hardened and ground surface ensures consistent contact conditions against mating bores. These properties make the component a practical, low‑maintenance instrument for toolrooms and inspection benches where reliability matters.

Practical integration into inspection workflows

The pin is suitable for quick go/no‑go checks, setting of plug gauges and comparative measurement against master references. Traceability is supported through the visible SKU and GTIN details, simplifying inventory and QC documentation. As part of the Metav IndustryLine, the item benefits from a vendor network focused on supply reliability and product consistency, which helps reduce procurement complexity. For production environments requiring regular spot checks and straightforward verification steps, this precision pin offers an economical route to maintain measurement standards and reduce downstream quality incidents.
