M323.431 Gauge pin — 4.31 mm ±0.001 mm, 50 mm length (Metav IndustryLine)

The M323.431 is a workshop‑grade precision gauge pin designed for end‑measurement and fit inspection in mechanical workshops, tool rooms and quality control benches.

• Workshop-grade construction for daily use
• Diameter 4.31 mm with ±0.001 mm accuracy
• Length 50 mm for reach and stable support
• Made from special steel for wear resistance

Reduce inspection time with micrometre-level certainty

A tolerance of ±0.001 mm (1 µm) places this precision pin in the category for very fine acceptance checks; such repeatability reduces uncertainty when verifying hole fits or component end dimensions. The tight diameter control at 4.31 mm makes the pin suitable for comparative gauging and plug checks where even small deviations can affect assembly or bearing clearance. Explaining the figure: a deviation of one micrometre is one thousandth of a millimetre — in practical terms this means the pin can detect and confirm dimensional deviations that would be invisible to lower‑resolution gauges, supporting faster decisions on part acceptance or rework.

Durable design that keeps workshop routines flowing

Constructed from special steel, the pin combines surface hardness with corrosion resistance to withstand regular contact and handling on the shop floor. The 50 mm length balances reach with rigidity, providing a stable reference when inserted into bores or used as a master for go/no‑go comparisons. The workshop execution emphasises robustness: finishes and geometries are chosen to tolerate frequent use, while the modest mass supports confident manual handling and quick placement during routine inspections.

Simple integration into quality workflows and inventory systems

The single‑item format is convenient for targeted checks or as a replacement in existing pin sets; traceable identifiers (SKU and GTIN) support stock control and audit trails in production environments. As a precision measuring accessory, the pin complements dial gauges, micrometres and bench fixtures and can be referenced in control plans to shorten inspection sequences. Clear technical data enables planners to assess the pin for compatibility with existing fixtures and to document measurement points in inspection reports, improving process reliability without introducing unnecessary complexity.
