Gauge pin M323.428 — 4.28 mm diameter, ±0.001 mm tolerance (Metav IndustryLine)

The gauge pin M323.428 is a workshop‑grade precision pin designed for end‑dimension checking and fixture alignment in fine mechanical and industrial metrology

• Diameter 4.28 mm with ±0.001 mm tolerance
• Length 50 mm for stable positioning
• Workshop version in special steel material
• Supplied in a transport case for safe handling

Micron precision that safeguards measurement decisions

The M323.428 offers a tolerance of ±0.001 mm (one micron), which places it among tools used for high‑precision verification in production and inspection routines. Such a fine tolerance means the pin is suited to tasks where dimensional certainty prevents rework and rejects: when verifying end dimensions, checking bore fits or confirming the alignment of fixtures. This level of accuracy reduces uncertainty in pass/fail judgments and supports consistent quality control. The small 4.28 mm diameter positions the pin within the micro (maximum measuring range 10–100 mm) classification, making it ideal for compact components and finemechanical assemblies.

Durable workshop design for repeatable handling

Constructed from special steel in a dedicated workshop version, the pin combines corrosion resistance and wear performance with a compact 50 mm shank that resists bending during use. The moderate length balances reach with rigidity so that measurements remain repeatable across many cycles. At about 0.008 kg, the pin is light to handle yet stable when seated in gauges or fixtures. Delivery in a transport case protects the gauge pin during storage and shipping, helping maintain surface integrity and dimensional stability — a practical advantage for busy workshops where tools travel between benches or job sites.

Practical advantages for inspection and fixture work

Beyond its dimensional specification, this precision pin simplifies everyday metrology tasks: it functions as a reference for end‑dimension checks, helps align jigs and fixtures, and serves as a physical gauge for assembly operations. The clearly defined ±0.001 mm tolerance allows integration into inspection plans where traceable repeatability matters, and the workshop specification prioritises robustness for routine use. For customers needing further technical data, material compatibility notes or batch handling recommendations, Metav’s documentation and product information provide focused guidance to match the pin to inspection requirements.
