Parallel blocks, pair M318.238.31 — 125 mm, hardened fine-ground special steel, ±0.01 mm (Metav IndustryLine)

The Parallel blocks, pair M318.238.31 are precision-ground supports for accurate workholding, setup and inspection in measurement and machining environments.

• Hardened, fine-ground special steel
• Height tolerance ±0.01 mm for repeatability
• 125 mm length for stable setups
• Conforms to DIN ISO 2768 standard

Accuracy that shortens setup time

These parallels deliver repeatable positioning thanks to a height tolerance of ±0.01 mm, which reduces the need for repeated adjustments during inspection or machining. The fine-grained flatness after grinding means datum faces sit true on the reference surface, improving precision in layout and assembly tasks. In practice, less time is spent re-measuring and more on productive machining; the measurable reduction in set-up variance supports faster quality checks and consistent part conformity.

Durability engineered for everyday workshop use

Manufactured from hardened, fine-ground special steel, the supports resist deformation under typical clamping pressures and maintain flatness over prolonged use. The ground finish minimises surface irregularities that could impair contact reliability, so the blocks remain dependable for repeated alignment, fixture support and inspection routines. At approximately 0.49 kg per pair, the balance of mass and stiffness makes these parallels robust enough for regular handling while remaining straightforward to position on the bench.

Designed for practical compatibility on the workbench

With a cross-section of 8 x 31 mm and a working length of 125 mm, the pair provides a stable platform for a wide range of components, from small assemblies to medium-sized housings. The compact profile eases insertion into vices and fixtures, while the length gives sufficient support to prevent tipping during layout, drilling or milling set-ups. Conforming to DIN ISO 2768 assures predictable manufacturing tolerances, so integration with existing gauges and datum systems is straightforward and verifiable.
