Parallel stop M318.246.1 — Precision 18 x 40 x 100 mm positioning block (Metav IndustryLine)

The Parallel stop M318.246.1 is a hardened, ground positioning block for 18 mm machine T‑slots, engineered to deliver repeatable locating and steady clamping in milling, drilling and fixture assemblies.

• Hardened, ground special steel
• Height tolerance 0/-0.02 mm IT5
• Fits 18 mm machine T-slots H8
• Delivered in pairs

Reproducible positioning for consistent production

The engineered geometry and tight height specification support repeatable positioning across serial operations. With nominal tolerance 0/‑0.02 mm in height and manufacturing to IT5, the block reduces variation at the workpiece datum and lowers rework rates. The compact footprint of 18 x 40 x 100 mm keeps the support rigid while offering enough contact area for secure clamping; this combination speeds up fixture set‑up and improves throughput in small‑batch and production environments.

Robust construction for long service life

Manufactured from special steel, ground and hardened, the component resists wear and preserves flatness over extended use. The ground surfaces provide a high level of planarity and low friction, which improves repeatability when parts are indexed or re‑located. Hardening increases resistance to indenting under clamp loads, so the support maintains its accuracy instead of deforming—an important factor when multiple set‑ups accumulate on the same datum surfaces.

Designed for T‑slot fixturing and stable clamping

Sized to engage 18 mm machine T‑slots with a tolerance class H8, the stop integrates cleanly into common machine tables and modular fixture systems. Supplied in pairs, the supports allow symmetrical locating of components or quick conversion between left/right datum positions. At 1.15 kg each, the mass contributes to stability during machining without being cumbersome to handle in typical workshop workflows.

Practical benefits that pay off on the shop floor

Adopting a hardened, precision stop reduces set‑up time and improves first‑pass yield; these are measurable gains for batch production and subcontract machining. The product is part of Metav IndustryLine, backed by Metav’s quality filter in Emmerich, which supports dependable stock and a consistent supply chain. The result is a reliable locating solution that supports efficient process control and lower overall production cost.
