Parallel blocks, pair M318.239.25 — 12 x 25 mm, 150 mm length by Metav IndustryLine

Parallel blocks M318.239.25 are precision support blocks designed to lift and align workpieces reliably during machining and inspection tasks, offering a compact cross-section and a long, stiff bearing surface for secure placement.

• Hardened, precision-ground special steel
• Height tolerance ±0.01 mm
• Cross-section 12 × 25 mm, length 150 mm

Consistent rigidity for secure set-ups

The pair provides a stiff bearing surface across the 150 mm length, reducing deflection during clamping or light machining operations. Their compact 12 × 25 mm profile preserves accessibility near vises and fixtures while still delivering mass where it counts; the result is less movement under load and more predictable machining results. Built weight and geometry are optimised for stable contact so that setups remain reproducible between cycles, shortening inspection time and improving throughput.

Ground and hardened faces for accurate inspection

Manufactured from special steel, finely ground and hardened, these parallels keep their faces plane and wear-resistant under repeated use. The declared ±0.01 mm height tolerance ensures that paired supports present minimal variation, which is essential when establishing reference planes for measurement or repeatable machining. Conformity with DIN ISO 2768 provides additional assurance that dimensional features meet common engineering tolerances, making the blocks suitable for quality-control benches and precision jigging.

Practical benefits on the shop floor

As a simple, reliable tool for everyday workshop tasks, the pair reduces setup time and improves operator confidence: the machined faces require no bedding-in, and the hardened surfaces tolerate clamping forces and light tool contact without immediate degradation. These support blocks are equally useful for inspection, milling, drilling and grinding fixtures where a repeatable datum is required. The robust finish and material composition make them a long-term investment that keeps maintenance efforts to a minimum.
