Hairline ruler 125 mm DIN 874/00 — hardened tool-steel precision rule (Metav IndustryLine)

A Hairline ruler 125 mm DIN 874/00 is a compact, hardened tool-steel precision rule intended for workshop measuring, layout and inspection where a stable straight reference is required

• Hardened, ground and lapped tool steel
• Complies with DIN 874/00
• Compact 125 mm length for fine work

Stable reference for fine measurement and layout

The compact straightedge is engineered as a precision reference for small components and quick verification tasks. Made from tool steel, fully hardened, ground and lapped, the blade gives a reliably flat datum that reduces measurement uncertainty during visual inspection and scribing. The short 125 mm length combines rigidity with manoeuvrability, making the rule suitable for tool room checks, quality-control benches and fine mechanical workshops. The blackened finish protects the metal surface and improves contrast against engraved or scribed lines, which supports faster, more confident alignment during repetitive tasks.

Robust construction for repeatable results in daily use

Durability is central to repeatability: the raw material and finishing steps ensure the reference edge resists wear and remains true under normal workshop handling. The hardened tool-steel construction resists nicks and deformation while the ground and lapped surfaces deliver a refined edge suitable for comparative inspection. As a result, the rule performs consistently when used for layout, edge checking or as a sighting aid on small assemblies. The light weight of around 0.1 kg and the compact size facilitate quick transfers between benches and reduce operator fatigue during frequent checks.

Practical handling, measurement workflow and care

Integration into everyday procedures is straightforward: the precision blade serves as a visual and physical guide for marking, aligning optical measuring devices or verifying straightness. The rule’s size and finish make it well suited for tasks where a full-length straightedge would be unwieldy. Maintenance is minimal — keep the edge free of chips and contamination, store in a protective sleeve or drawer to preserve the lapped surface, and avoid corrosive agents to maintain the blackened finish. For structured inspection routines the rule can be paired with magnified scales or microscopes for improved visual resolution during fine layout operations.

FAQ

What is the hairline ruler best used for?
The hairline ruler 125 mm DIN 874/00 is designed for fine layout, reference checks and short-range straightness verification in tool rooms and inspection benches.

How does the material and finish affect performance?
The tool-steel construction, being fully hardened and ground and lapped, provides a wear-resistant reference edge; the blackened finish reduces glare and helps protect against surface corrosion.

Is this rule suitable for visual inspection with magnification?
Yes — the compact, stable blade is well suited as a datum for magnified visual comparison and fine scribing work where a short, rigid reference is advantageous.

How should the ruler be cared for to maintain accuracy?
Keep the edge free from nicks and debris, avoid corrosive cleaners, and store the rule in a protective sleeve or drawer to preserve the lapped surface.
