Parallel block pair M318.237.21 — 100 mm, hardened fine-ground special steel (Metav IndustryLine)

The parallel block pair M318.237.21 is a precision support set designed to provide stable, parallel elevation for machining, clamping and inspection tasks in the toolroom and production environment.

• Hardened, fine-ground special steel
• Precise height tolerance ±0.01 mm
• 100 mm length for universal use
• Conforms to DIN ISO 2768

Repeatable precision for reliable set-ups

The pair delivers consistent support for workpieces thanks to the hardened and fine-ground surfaces that resist wear and preserve geometry over time. The declared height tolerance ±0.01 mm ensures repeatability when establishing reference planes or clamping heights, reducing trial adjustments and minimising scrap. For workshop settings where reproducible set-ups shorten machining cycles, these parallels act as a compact, robust spacer that keeps fixturing predictable.

Stable clamping and handling for everyday machining

With a 100 mm length and a cross-section of 3 x 21 mm, the blocks offer a balance between reach and stiffness that suits vice-mounted and fixture applications. The compact pair is easy to position and manoeuvre, while the fine-ground faces provide a reliable contact surface for vice jaws or support ledges. Their modest mass makes them simple to handle without compromising the stability required for milling, drilling or measuring operations.

Built to recognised workshop standards

Manufactured from special steel, fine-ground and hardened, the components comply with DIN ISO 2768, reflecting suitability for professional use in metalworking environments. Traceable identification (SKU M318.237.21, GTIN available) supports asset management and procurement tracking in industrial supply chains. The combination of standard conformity and clear product data helps maintenance and quality teams integrate the blocks into documented set-up procedures.

Low-maintenance durability and practical benefit

The conditioned surfaces limit microscopic deformation under clamping pressure, which prolongs useful life and reduces the need for frequent replacements. Regular cleaning and light lubrication of contact faces will keep the blocks performing as designed; their construction prioritises precision and serviceability so that measurement references and clamping heights remain dependable across repetitive cycles.
