Hairline straight edge 800 mm (DIN 874/0) — Metav IndustryLine, hardened tool steel

The Hairline straight edge 800 mm (DIN 874/0) is a hardened, ground and lapped tool-steel rule with a blackened finish, intended for accurate straightness and flatness checks in workshop and inspection environments.

• 800 mm hardened, ground and lapped blade
• Complies with DIN 874/0 tolerance standard
• Blackened finish reduces glare and corrosion
• Solid tool-steel construction for stability

Reliable reference for inspection and layout work

The straight edge serves as a stable reference line for inspection, scribing and machine set-up, offering conformity with DIN 874/0 so that results can be compared against a recognised tolerance class. Because the blade is ground and lapped, the surface presents a uniform contact face that reduces point loading and localised error; this improves repeatability when checking flatness or aligning components. The calibrated geometry of the edge minimises interpretation uncertainty during quality control tasks and supports faster decision making on whether a part meets specification.

Robust construction that maintains accuracy over time

Constructed from tool steel, fully hardened and finished by grinding and lapping, the blade resists wear and keeps its reference profile under frequent use. The blackened finish reduces glare under workshop lighting and offers a degree of surface protection against corrosion, while the substantial mass contributes to stability during measurement and layout tasks. These attributes reduce the need for constant rechecking and support a steady production flow by lowering the risk of measurement-induced rework.

Practical benefits for the workshop and inspection bench

At 800 mm length the straight edge strikes a pragmatic balance between reach and handling: long enough for many fixture and housing checks, yet manageable for single-person use. The weight and construction improve contact consistency on measured surfaces, aiding quicker assessments with dial indicators or visual hairline alignment. Supplied as a branded Metav IndustryLine tool, the item aligns with Metav’s approach to democratising precision: reliable quality, broad stock availability and straightforward integration into existing metrology routines help reduce supplier overhead and keep inspections on schedule.
