Hairline straight edge 400 mm — DIN 874/00, hardened tool steel, blackened finish (Metav IndustryLine)

Hairline straight edge 400 mm DIN 874/00 is a precision reference for inspection, alignment and layout tasks in workshop and production environments

• DIN 874/00 accuracy standard
• Fully hardened, ground and lapped
• Blackened finish for glare reduction
• 400 mm measurement length

Reliable reference for inspection and setup

The combination of DIN 874/00 conformity and a finely finished edge provides a reproducible datum for visual inspections and machine setup. Conformance to the standard indicates that straightness and edge quality meet established tolerances, which reduces measurement uncertainty and supports consistent quality control. Using a certified straight edge as the reference reduces rework and speeds up inspection routines, making processes measurable and repeatable with professional rigour.

Robust construction for long service life

Manufactured from tool steel that is fully hardened, ground and lapped, the instrument resists wear at the contact edge and retains its geometry under normal workshop use. The blackened surface minimises glare under shop lighting and offers additional surface protection against surface corrosion. The ground and lapped finishing steps ensure a uniformly flat reference face; in practical terms this means fewer adjustments and a longer interval between checks, delivering lower total cost of ownership for routine inspection equipment.

Practical handling and workshop integration

With a mid-length measuring span of 400 mm, the straight edge balances reach and rigidity for everyday tasks such as checking planeness, aligning guides and verifying machined faces. The slim hairline edge assists in precise visual alignment without obscuring the workpiece, while the robust body keeps the edge stable during use. For buyers who require further technical clarification or measurement planning, Metav provides straightforward application advice so the tool can be integrated reliably into existing inspection routines.
