Parallel block pair M318.239.30 — 150 mm hardened special steel (Metav IndustryLine)

A pair of Parallel block M318.239.30 designed as hardened, finely ground supports for accurate set‑up, clamping and inspection tasks in machine shops and metrology stations.

• Hardened, finely ground special steel
• Length 150 mm for stable support
• Height tolerance ±0.01 mm
• Cross-section 12 x 30 mm

Reliable support that keeps measurements reproducible

The M318.239.30 pair is manufactured from special steel, then finely ground and hardened to ensure minimal wear and stable contact surfaces. The combination of material treatment and geometry yields consistent seating and repeatable results during setting, inspection and short‑run machining. With a specified height tolerance of ±0.01 mm, these blocks provide a clear, measurable baseline that supports quality control processes and reduces setup variation in everyday workshop practice.

Robust construction for industrial handling and long service life

A hardened surface finish resists dents and deformation, so the blocks maintain their flatness under regular use. Compliance with DIN ISO 2768 underlines the manufacturing tolerances and dimensional control applied during production. The combination of a 150 mm length and the chosen heat treatment increases bending resistance compared with shorter parallels, delivering a dependable reference when locating or supporting components during inspection and machining operations.

Compact geometry for simple positioning and strong contact

The 12 x 30 mm cross-section provides a balanced ratio of contact area and accessibility: large enough to give stable support, yet slim enough to position in tight fixtures or between jaws. At approximately 0.71 kg for the pair, the blocks are easy to handle while retaining sufficient mass to resist slipping under light clamping forces. These parallels are therefore a practical solution when consistent planar support and repeatable fixturing are required across a range of workshop tasks.

Practical uses and integration in the workshop workflow

Designed as a pair, these blocks are ideal for supporting workpieces during marking out, inspection and light machining, or for raising components to a defined datum height during assembly. Their durable finish makes them suitable for regular use as a workshop reference and for quality checks with calipers or height gauges. For buyers seeking dependable execution in everyday metrology tasks, these parallels offer a straightforward way to increase process reliability and reproducibility.
