Metav IndustryLine Parallel Stop M318.241.1 — Parallel support 8 x 40 x 100 mm, hardened special steel

A Parallel Stop M318.241.1 engineered for precise workpiece positioning in 8 mm machine T‑slots, suitable for clamping and fixture setups in workshop and production environments

• Hardened, ground special steel construction
• Height tolerance IT5 (0 / -0.02 mm)
• For 8 mm machine T‑slots (tolerance H8)
• Supplied in pairs for consistent setups

Precise, stable support for production and inspection

The M318.241.1 is manufactured from special steel, ground and hardened to ensure long service life and minimal wear. The 100 mm length and robust profile deliver stable contact zones, while the specified height tolerance IT5 (0 / -0.02 mm) guarantees high positional accuracy for repeatable setups. In practice, this means quicker alignment, fewer rejects and a measurable reduction in setup time where repeatability matters.

Tight tolerances that translate into reliable results

Built to interface with 8 mm T‑slots held to tolerance H8, the parallel support provides defined seating and predictable clamping behaviour. The nominal tolerance of 0 / -0.02 mm in height ensures consistent datum points across paired supports, improving measured reproducibility on jigs and inspection fixtures. For shops that value measurable outcomes, the combination of hardened surfaces and close tolerances reduces rework and increases throughput.

Robust design that integrates seamlessly into fixtures

At approximately 0.5 kg per unit and supplied in pairs, these parallels are easy to handle while offering the rigidity needed for machining and metrology tasks. The ground contact faces produce stable bearing areas for small to medium workpieces, and the compact 8 mm thickness suits standard T‑slot profiles without obstructing adjacent tooling. The finished surfaces resist deformation under clamping forces, supporting consistent repeatability across production runs.
