Hairline Square 150 x 100 mm – hardened tool steel, Class 00 (Metav IndustryLine)

Hairline Square 150 x 100 mm for precision layout and inspection of right angles in metalworking and toolmaking

• DIN 875 Class 00 accuracy
• Hardened tool steel edge
• Black-oxidised hairline measuring edge
• Compact 150 x 100 mm size

Repeatable right-angle checks with metrology-grade accuracy

This square is manufactured to DIN 875 and delivered in Class 00, providing a measurement standard intended for the most demanding layout and inspection tasks. The geometry is held to tight tolerances so that right angles remain reproducible when used for scribing, checking mating faces or validating jig alignment. Conforming to this standard means the tool supplies an objective basis for quality control and reduces rework by identifying squareness errors early in the process.

Durable construction for everyday workshop handling

Built from tool steel with a hardened hairline edge and a black-oxidised finish, the instrument resists blunting and surface corrosion while preserving the fine measuring edge required for precise scribing and visual alignment. The hardened measuring edge reduces wear during repeated contact with metal and abrasive surfaces, extending the service life of the instrument and maintaining measurement stability over time. The protective finish also minimises reflections, improving visibility of the hairline in varied lighting.

Practical dimensions and efficient layout workflow

With a working face of 150 x 100 mm, the square offers a balance between reach and rigidity that suits bench work, toolmaking and general machine-shop tasks. Its compact size allows secure single‑hand positioning while the blunt masses typical of larger squares are avoided, which reduces measurement uncertainty due to flex. The hairline edge provides a crisp reference for scribing and optical alignment; when paired with standard layout blocks or surface-plate setups, this format helps maintain a fast and reliable workflow without sacrificing precision.
