Parallel support pair M318.238.21 — hardened special steel, 8 × 21 mm, 125 mm length (Metav IndustryLine)

The Parallel support pair M318.238.21 is designed as a compact, stable support solution for workshop set-ups, inspection fixtures and machining jigs where consistent parallelism and repeatable seating are required.

• Hardened, finely ground special steel
• Height tolerance ±0.01 mm
• Length 125 mm for stable support
• Conforms to DIN ISO 2768

Stable reference surfaces for faster, reliable set-ups

Accurate fixturing begins with trustworthy reference elements. These parallels are manufactured from special steel, precisely hardened and finely ground to create flat, wear-resistant contact faces. The result is a stable datum that reduces setup time and minimises rework, because components rest uniformly on surfaces engineered for repeatability. For production environments where small deviations cascade into scrap or rework costs, the consistent geometry of these supports contributes directly to process efficiency.

Precision where it counts: measurable tolerance and workmanship

Machining and inspection demand predictable tolerances. The pair carries a declared height tolerance of ±0.01 mm, which ensures that stacked or matched references remain within tight limits for alignment tasks. The adherence to DIN ISO 2768 underlines the controlled manufacturing process and provides a verifiable standard for integration into quality-controlled workflows. These features make the items particularly suitable for tooling benches, set-up stations and quality labs that require reliable, metric traceability.

Compact dimensions for flexible use and handling

With a cross-section of 8 × 21 mm and a length of 125 mm, the supports combine low profile with sufficient stiffness for most workshop tasks. The slender footprint makes them easy to position in confined fixtures or vice jaws while offering enough bearing area for stable support. As a matched pair, they are ready for immediate use in parallel clamping, height gauging and component levelling without additional matching or pairing work, which streamlines assembly and inspection procedures.

Built to last — material choice and practical benefits

The selection of special steel, together with the hardening and grinding treatments, produces contact faces that resist wear and maintain flatness over time. This reduces the frequency of replacement and maintains measurement integrity across repetitive operations. For operations that demand a pragmatic balance of durability and precision, these parallels offer longevity that pays back through fewer stoppages and more consistent production output.
