Parallel blocks set M318.235 — precision 160 mm parallels, hardened and fine-ground (Metav IndustryLine)

A precision set of Parallel blocks M318.235 designed for stable workholding and accurate reference support in workshop fixturing and inspection applications.

• Hardened steel, HRC > 56 for long service life
• Fine-ground surfaces for precision fitting
• Nominal height tolerance ±0.01 mm
• 160 mm length for stable support in fixtures

Reliable support for jigs and inspection benches

The set offers consistent bearing surfaces that reduce setup variation when locating and supporting workpieces. Manufactured from special steel, fine-ground and hardened, the blocks maintain geometry under frequent use so that fixtures remain true over many cycles. The combination of HRC > 56 and fine surface finish minimises wear and ensures that stacking or repeated contact does not compromise dimensional stability. For production environments where repeatable positioning shortens cycle times, these parallels act as a low-effort way to preserve accuracy.

Repeatability and measurable precision for quality control

With a nominal height tolerance of ±0.01 mm and documented flatness down to 0.005 mm, the set is tailored for tasks that demand measurable reproducibility rather than subjective alignment. The clear numeric tolerances support quality documentation and process control: inspection routines can reference the blocks as calibrated reference faces, and the reproducible geometry simplifies comparative gauging. Where traceable setups are required, these precision parallels give a quantifiable baseline for repeat inspections and process audits.

Design choices that reduce handling error and improve ergonomics

At 160 mm length and with balanced cross-sections, the parallels deliver a stable contact area that reduces tipping risk during manual placement. The polished, fine-ground finish eases sliding and alignment when stacking or shimming components, cutting setup time in clutch operations. Because the set comprises matched pairs, alignment of opposing faces is straightforward, which benefits quick-change jigs and small-batch production where frequent part swaps are needed. The practical design supports faster, safer handling without sacrificing the engineered accuracy.

Durable construction for workshop longevity

The choice of hardened special steel and adherence to DIN ISO 2768 tolerances result in a robust toolset that tolerates the rigours of daily workshop life. Hardness at HRC > 56 delivers abrasion resistance while the ground surfaces maintain contact integrity, so performance is preserved even under repeated load. This durability lowers the need for frequent replacement and reduces downtime associated with worn support elements, contributing to steadier production throughput and lower lifecycle cost.

FAQ

What accuracy can be expected from the parallel set during stacking?
Stacking accuracy is governed by the nominal height tolerance of ±0.01 mm and the stated flatness of 0.005 mm for the Parallel blocks set M318.235, providing repeatable results suitable for routine inspection and fixturing.

Are the parallels suitable for heavy-duty workshop use?
Yes, the set is manufactured from hardened special steel with HRC > 56, which gives the parallels robust wear resistance for frequent workshop use.

Can these parallels be used for precision inspection tasks?
The fine-ground surfaces and tight tolerances make the M318.235 set appropriate as reference supports in many inspection and quality-control scenarios.

Does the set include multiple widths for flexible fixturing?
The set contains nine paired widths (10 to 42 mm), enabling a variety of support configurations for different workpiece geometries.

Which standard applies to the manufacture of these parallels?
Production follows DIN ISO 2768 general tolerances and the technical data lists measurable tolerances for traceability.
