Parallel blocks, pair M318.239.31 — Hardened special steel, 150 mm length

Parallel blocks 150 mm provide rigid, precisely ground support for machining and inspection

• Hardened, finely ground special steel
• Height tolerance ±0.01 mm
• 150 mm length for extended support

Precise support that improves measurement and machining consistency

The pair of parallel blocks is manufactured from special steel, finely ground and hardened, delivering a stable reference surface that resists deformation under clamping forces. The declared height tolerance of ±0.01 mm ensures repeatable results when aligning workpieces in vices or under measuring instruments. For quality assurance and process control, such tolerances reduce rework and shorten inspection cycles by providing a reliable datum across repetitive setups.

Stable geometry for machining and inspection workflows

With a cross-section of 8 x 31 mm and a length of 150 mm, these blocks combine a compact footprint with sufficient contact area to support medium-sized components. The hardened surface minimises wear during repeated use, while the finely ground finish gives consistently low surface roughness for better seating. In practical terms, this means fewer slips or misalignments when clamping, and more accurate transfer of part positions between machine and measuring station.

Designed for integration in professional workshops

The parallels are specified to DIN ISO 2768, making them compatible with standardised workshop procedures and machine setups. The modest total mass provides easy handling while still offering sufficient mass to remain stable during machining or inspection. Supplied as a pair, the set is intended for use as matched supports or spacers between vice jaws, on surface plates, or as fixtures during optical and tactile measurement. Their straightforward geometry simplifies fixturing without the need for complex adjustment.

Built for durable daily use and simple maintenance

The combination of hardened material and fine grinding makes maintenance straightforward: occasional cleaning and light oiling preserve the datum surfaces and prevent corrosion. Because the blocks are made from high-grade steel and processed to tight tolerances, replacements are infrequent; this contributes to lower long-term operating costs and uninterrupted production runs. The GTIN and article number support traceability and inventory control in procurement systems.
