Hairline straightedge 300 mm (DIN 874/00) — hardened tool steel, blackened (Metav IndustryLine)

A Hairline straightedge 300 mm (DIN 874/00) designed for precision alignment and visual inspection in workshops and inspection bays

• Hardened tool steel, ground and lapped
• Conforms to DIN 874/00 for straightness
• Blackened finish for reduced glare
• Compact 300 mm length for fine inspection

Precision where repeatable results matter

The straightedge is manufactured from fully hardened tool steel, subsequently ground and lapped to deliver a stable reference surface with very low form deviation. Conformity to DIN 874/00 and the indicated grade 00 ensures the instrument functions as a reliable reference for visual and tactile checks of straightness, squareness and run‑out. This level of manufacturing control reduces measurement uncertainty and supports repeatable setup routines in production and inspection processes, making the tool suitable for toolrooms, inspection benches and fine mechanical assembly.

Practical benefits for everyday inspection tasks

At 300 mm, the length provides a practical compromise between reach and stiffness: long enough for routine layout and alignment, yet compact for tight workspaces and one‑hand handling. The blackened finish lowers surface reflections during visual comparison and protects the steel against superficial corrosion in standard workshop atmospheres. With a low-profile edge and clearly defined reference line, the straightedge simplifies quick checks on machine beds, fixture faces and component edges, speeding up set-up without adding process complexity.

Durable design and maintenance advice for longevity

The combination of hardened steel and fine finishing delivers durability under frequent use. Regular care is straightforward: keep the faces clean and dry, remove swarf and grit after each shift and store the instrument flat in a protective sleeve or drawer to avoid edge damage. Light oiling of the surface will protect against rust when the tool is not in use. Backed by Metav’s quality filter, this straightedge is intended to provide long service life under normal workshop conditions while maintaining the straightness required for inspection tasks.
