End gauge 1.39 mm — DIN EN ISO 3650, Grade 1, hardened special steel (Metav IndustryLine)

The End gauge 1.39 mm is a compact precision check gauge for tactile conformity testing of small external diameters, suitable for production inspection and maintenance tasks in metalworking environments.

• DIN EN ISO 3650 Grade 1 accuracy
• Hardened special steel for wear resistance
• Nominal dimension 1.39 mm in compact form

Repeatable, standardised go/no‑go checking for small diameters

The gauge is manufactured to DIN EN ISO 3650 and specified as Grade 1, which ensures tight tolerances for routine acceptance tests. In practice, this means the component checks are consistent with recognised international standards, reducing ambiguity in inspection results and supporting clear pass/fail decisions on the shop floor. The 1.39 mm nominal dimension denotes the calibrated contact size used for external diameter verification, providing a direct, reliable reference for production control.

Durable construction reduces rework and downtime

Made from hardened special steel, the gauge offers elevated resistance to wear during repeated engagements, which preserves dimensional integrity over time. The compact cross‑section of 30 × 9 mm (applicable for nominal sizes up to 10 mm) combines handling convenience with sufficient stiffness to avoid unwanted deformation during manual use. This robustness translates into fewer replacements, less unplanned downtime and a reduced need for corrective machining.

Designed for practical workshop workflows

The plain, unambiguous geometry of the gauge supports rapid tactile checks in assembly and inspection processes. The low mass (approx. 0.006 kg) and compact profile make it easy to integrate into fixture checks or to keep at the testing station for intermittent verification. Traceability is straightforward thanks to the SKU M319.0139.1 and GTIN 4054469130934, aiding inventory control and documentation within quality systems.

Clear technical traceability for compliance and procurement

The product is listed under the End gauges category and carries the customs tariff number 90173000, which simplifies procurement and customs handling. Supplied by Metav IndustryLine, the gauge benefits from Metav’s focus on accessible precision: a documented supply chain and a broad product portfolio make it easier to standardise inspection tools across multiple workstations or sites. The compact gauge supports efficient sample inspection and contributes to a measurable improvement in first‑pass quality.
