Micrometer setting standard M304.313 — 125 mm, ±2.5 µm (Metav IndustryLine)

The Micrometer setting standard M304.313 is a precision accessory for setting and checking micrometer outside‑measurement spindles in workshop and calibration environments.

• 125 mm nominal length
• High calibration accuracy ±2.5 µm
• Flat, lapped measuring faces
• With thermal protection

Reduce setup uncertainty with traceable reference values

A compact, stable gauge with a 125 mm nominal length delivers a defined reference for setting micrometer anvils and spindles. The declared accuracy of ±2.5 µm (0.0025 mm) translates into significantly lower setup variability compared with informal references, which speeds first‑run approvals and reduces scrap. By using a dedicated setting standard, tolerance stacks are controlled at the point of measurement — a pragmatic, performance‑led approach for routine workshop quality control.

Workshop‑grade construction for consistent handling

Engineered with flat measuring faces and an 8 mm diameter seating, the gauge offers a secure contact geometry that resists tilt during adjustment. The design includes thermal protection, which moderates short‑term temperature influences during handling and prevents immediate thermal drift while the tool is in use. At approximately 0.1 kg, the component is lightweight and easy to position, supporting quick repeat checks without introducing significant handling fatigue.

Practical benefits for measurement workflows

As a dedicated setting accessory, the standard provides reproducible reference distances for outside measurements and supports faster, more reliable micrometer adjustments. The accessory is listed under accessory categories and is suitable for integration into workshop metrology routines where reproducibility and throughput matter. For laboratories aiming to tighten tolerances, this gauge functions as a cost‑effective reference that complements existing measurement chains and quality documentation.
