M323.121 test pin — Metav IndustryLine, 1.21 mm ±0.001 mm, 50 mm length

The M323.121 test pin is a precision gauge pin for workshop inspection and end‑dimension verification, engineered to check small bores, fits and reference gauges under routine production conditions

• Workshop-grade precision construction
• Diameter 1.21 mm with ±0.001 mm tolerance
• 50 mm hardened, stable measuring length
• Supplied in protective transport case

Accuracy that secures measurement confidence

The defining advantage of this gauge pin is its ±0.001 mm declared accuracy, which reduces uncertainty in acceptance testing and go/no‑go checks. In practice, such fine tolerance translates into consistent pass/fail decisions on small bores and press‑fits; the tight specification minimises rework and supports traceable inspection records. For users with standard measuring equipment, the pin provides a stable reference: its nominal 1.21 mm diameter serves as a calibrated limit when checking mating parts or verifying plug gauges used in serial production.

Robust construction for everyday workshop use

Manufactured from special steel and presented in a workshop specification, the measuring probe withstands regular handling and the mechanical stresses of shop‑floor use. The 50 mm length balances access and rigidity, reducing flex during insertion while allowing access to recessed features. Supplied individually and protected in a transport case, the pin is easy to store and move between workstations without risk of damage, keeping inspection capability close to the production process and reducing downtime caused by fragile tooling.

Designed to fit inspection workflows

The single, precision‑ground pin integrates directly into common verification routines: it can be used as a reference for bore gauges, as a sizing master for small‑part fixtures, or for end‑dimension confirmation during final inspection. Clear labelling and the industry‑standard GTIN enable straightforward inventory management and traceability within quality systems. Where higher throughput is required, the repeatability of this measuring element supports automated gauge checking and periodic process audits, helping to maintain consistent quality levels across batches.
