Parallel stop — 12 × 80 × 120 mm, for 12 mm T‑slots (Metav IndustryLine)

The Parallel stop, 12 × 80 × 120 mm is a precision locating block designed to engage 12 mm machine T‑slots and provide stable, repeatable positioning for fixtures and workpieces in machining and assembly environments.

• Hardened, ground special steel
• Height tolerance IT5 for consistent location
• Designed for 12 mm T‑slot width
• Delivered in pairs for matched set-ups

Reliable material and dimensional precision for consistent results

Manufactured from hardened and ground special steel, this locating block delivers the rigidity required for accurate positioning under machining forces. The component’s height tolerance (IT5) and nominal tolerance of 0 / -0.02 mm ensure that each stop presents a reproducible datum face, reducing the need for repetitive adjustments. For workshop applications where small deviations translate into scrap or rework, the combination of material treatment and tight tolerance translates directly into less downtime and more predictable output.

Quick integration into machine T‑slots and improved set‑up efficiency

Configured specifically for a 12 mm T‑slot, the geometry allows fast installation and secure seating in machine tables and fixtures with an H8 slot tolerance. The block’s 12 mm thickness and the 120 mm length provide a stable contact area while the 80 mm height gives a clear datum plane for clamps or workpieces. This dimensional balance supports straightforward clamping strategies and reduces the number of alignment operations, which speeds up changeovers and improves throughput on recurring production runs.

Match‑paired delivery and workshop resilience

Supplied in pairs, the blocks are matched for height and flatness so that two‑point locating and parallel supports behave predictably when used together. The parts are ground on the critical faces and hardened to withstand wear from repeated clamping, giving a long service life even under regular shopfloor use. At a mass of 1.8 kg per item, the components combine substantial rigidity with manageable handling during set‑up and storage, which helps keep workstation ergonomics practical without compromising stability.

Where this block adds value in practice

This locating block is suited to machine shops, jigs and fixture builders, and production lines that require a reliable datum for repetitive tasks. By providing a hardened datum and a precise height tolerance, the component reduces the cumulative error in assemblies and ensures that downstream operations see fewer dimensional variations. The specific compatibility with 12 mm T‑slots and H8 slot tolerances means the block integrates seamlessly into common clamping systems without modifications, enabling faster implementation in existing workflows.
