M323.121 Gauge Pin (single) — 1.21 mm, ±0.001 mm, 50 mm

The M323.121 Gauge Pin (single) is an ultra-compact, workshop-grade precision pin for end-dimension checks and micromechanical inspection.

• Diameter 1.21 mm, high-precision fit
• Tolerance ±0.001 mm for repeatable checks
• Workshop‑grade special steel construction
• Supplied in a protective transport case

Accuracy that reduces uncertainty and rework

The main strength lies in the ±0.001 mm specification, which delivers a degree of repeatability suitable for demanding end‑dimension controls and plug‑gauge comparisons. A tolerance of this order minimises ambiguous readings and supports consistent go/no‑go decisions on the production line. By using a dedicated, small‑diameter pin the risk of misalignment is reduced, so inspection cycles become more predictable and non‑conforming parts are detected earlier. The compact geometry also lends itself to fine fixtures and measuring nests used in micromechanical assembly.

Built for daily workshop use and secure transport

Constructed from special steel and finished as a workshop‑grade item, this gauge pin balances wear resistance with practical handling. The 50 mm shaft length offers enough reach for most small‑part checks while remaining easy to manoeuvre by hand or in a fixture. Delivery includes a protective transport case, designed to protect the pin during storage and transit; the case is intended for transport protection rather than permanent workshop storage. These design choices reduce the likelihood of damage and preserve the calibrated condition of the pin between uses.

Integrates smoothly into inspection routines

Compact, lightweight and precise, the pin is suited to inline quality checks, bench inspection and validation of end dimensions on turned or milled components. The small mass and consistent geometry make it straightforward to use in automated test nests or alongside manual gauging operations. Traceability is supported by the clear article and identification data, helping to document which instrument was used for a given measurement. As a standard workshop tool, it complements broader Metav IndustryLine offerings and fits into procurement strategies that favour repeatable quality and dependable supply.
