Parallel blocks, pair »M318.238.42« – 14 x 42 mm cross-section, 125 mm length by Metav IndustryLine

The Parallel blocks, pair M318.238.42 are precision support blocks for machining and inspection, designed to maintain consistent workpiece height and parallelism during clamping and setup operations.

• Finely ground and hardened special steel
• Height tolerance ±0.01 mm
• Stable 125 mm length for even support
• Supplied as a matched pair

Improve set-up repeatability and machine throughput

These parallels act as a reliable precision support to lift and stabilise workpieces during milling, drilling and inspection operations. The combination of special steel that is finely ground and hardened with a nominal height tolerance of ±0.01 mm reduces variability between set-ups; this leads to fewer alignment checks and less rework. Supplied as a matched pair, the components ensure identical contact geometry on both sides of the workpiece, preserving parallelism across the clamped surface and helping to maintain consistent machining results across production batches.

Built for workshop durability and accurate handling

The robust construction and surface finish make these blocks suitable for regular shopfloor use where stable support is essential. The 14 x 42 mm cross-section and 125 mm length provide a balance between stiffness and accessibility: long enough to support larger contact areas, yet compact enough for straightforward handling and positioning. Ground faces offer low surface deviation and reliable contact points, while the hardened substrate increases resistance to wear and preserves measurement-critical dimensions over time. This combination reduces the frequency of replacement and supports continuous operation in a production environment.

Practical applications that save time and lower risk

Use the pair for setting parallel datum surfaces on machine tables, for supporting parts during multi-spot machining or for repeatable inspection fixtures. The matched geometry simplifies repeat jobs: once a fixture height is proven, it can be recreated quickly with minimal adjustment. The attributes of these blocks translate into a concrete operational benefit — fewer set-up cycles and improved first-pass yield. For assembly and quality-control teams the result is a more dependable workflow and increased confidence in dimensional results, backed by Metav IndustryLine quality standards.

FAQ

What is the primary use of these parallel blocks?
The parallel blocks are intended as precision supports for machining, clamping and inspection tasks where consistent height and parallelism are required; the M318.238.42 pair is designed to stabilise parts on machine tables.

Are the surfaces ready for direct use or do they require preparation?
The surfaces are finely ground and hardened, so the parallels can be used directly for accurate support without additional dressing.

How tight is the height tolerance and what does that mean in practice?
With a nominal height tolerance of ±0.01 mm, the blocks provide consistent contact heights suitable for precision workshop and production use, minimising the need for repeated adjustments.

Can these parallels be used in inspection fixtures?
Yes, the matched geometry and ground faces make the pair suitable for use in inspection fixtures and comparative measurement set-ups where parallel reference planes are required.

Which standard governs the manufacturing of these parallels?
Manufacture complies with DIN ISO 2768, reflecting general dimensional tolerances applied during production of the M318.238.42 pair.
