Gauge Ball Pair M318.411 — 1 mm, hardened chrome steel, 0.003 mm accuracy (Metav IndustryLine)

The Gauge Ball Pair M318.411 is a compact precision reference for dimensional inspection and master-gauge applications, designed for use in metrology labs, incoming inspection and machine setup.

• Hardened chrome steel, hardness > HRC 62
• Diameter 1 mm with 0.003 mm accuracy
• Diameter tolerance ±0.00008 mm
• Supplied as a matched pair for comparative checks

Consistent reference values for repeatable quality control

Precision is the primary benefit of these gauge spheres: with a specified accuracy of 0.003 mm and a diameter tolerance of ±0.00008 mm, the pair provides a stable baseline for comparative measurements and machine performance checks. The extremely low surface roughness (0.00001) reduces measurement noise at contact points, improving repeatability when used with optical probes, tactile probes or comparator setups. For production environments where traceable, repeatable references matter, these spheres deliver measurable improvements in process control.

Durable material and finish for long service life

Manufactured from hardened chrome steel and rated above HRC 62, the balls combine hardness with corrosion-resistant chrome finish to resist wear during frequent contact measurement. The high hardness reduces profile change over time, so the reference geometry remains reliable across many inspection cycles. This material choice, together with the fine surface finish, makes the pair suitable for use as master gauges in fixture set-up, tactile probe checks and precision alignment tasks where stable contact behaviour is required.

Practical handling and integration into inspection workflows

Supplied as a matched set of two precision balls, the pair is intended for comparative checks, datum formation and quick functional tests on fixtures and machine probes. The compact 1 mm diameter makes the spheres suitable for small, fine-featured components and micro-measurements while remaining compatible with a broad range of gauging fixtures. The item is identified by SKU M318.411 and GTIN 4054469183992, facilitating inventory management and procurement in quality departments that require clear traceability and part control.
