Metav IndustryLine outside micrometer M304.419 — 275–300 mm, 0.01 mm resolution

Metav IndustryLine outside micrometer M304.419 is a heavy‑duty workshop micrometer designed for precise external measurements on medium to large components, suitable for machine shops and inspection benches

• Ratchet stop for consistent measuring force
• 0.01 mm graduated reading
• Large 275–300 mm measuring range
• Compliant with DIN 863 standard

Reliable repeatability for production and inspection

The combination of a ratchet stop and a fine 0.01 mm graduation ensures highly reproducible readings, making this micrometer a pragmatic choice where process stability matters. The ratchet prevents over‑torque on the spindle, so measurements remain consistent even when multiple operators are involved. Conformance with DIN 863 confirms that the instrument meets recognised workshop standards, which supports quality control procedures and reduces measurement variability on serial parts.

Robust construction for workshop environments

A painted frame with a matt chrome‑plated measuring drum delivers corrosion resistance and long‑term durability under daily use. The spindle features a 0.5 mm pitch and a 6.5 mm diameter for a stable contact point and smooth travel, which helps to maintain measuring accuracy over the 275–300 mm range. The presence of true measuring faces provides reliable contact geometry; the overall construction favours a balance between stiffness and manageable handling during routine checks.

Practical application and handling benefits

This outside micrometer is aimed at machinists and inspection technicians who need dependable external measurements on larger workpieces that exceed standard caliper reach. The analogue readout is straightforward for quick checks and aligns with traditional workshop workflows, while the ratchet stop aids repeatable contact force. For customers seeking a no‑frills, mechanically robust instrument that integrates easily into existing inspection setups, this device supports efficient throughput without complex electronics.
