Assembly rule M214.746 — Grade 1, 1500 mm aluminium‑magnesium

The Assembly rule M214.746 is an industrial‑grade alignment straightedge designed for precise positioning and reliable reference across medium‑to‑large assemblies.

• Grade 1 dimensional accuracy
• 1500 mm effective length
• Aluminium‑magnesium construction
• Integrated relief holes for mounting

Engineered precision that speeds set‑up and reduces rework

The combination of Grade 1 manufacturing and a guaranteed flatness 0.017 mm gives a stable reference for alignment and inspection tasks. This level of planarity minimises adjustment cycles on jigs and fixtures, so production processes become more predictable and efficient. The straightedge acts as a reliable datum for machining set‑ups and assembly benches where reproducible positioning is essential.

Stiffness matched to practical handling

A measured weight 4.56 kg over the 1500 mm length balances rigidity and manoeuvrability; the profile provides the stiffness required for long runs while remaining manageable during installation. The 100 mm overall height and 40 mm width contribute to a low bending tendency under normal workshop handling, which supports repeatable measurements and alignment without cumbersome lifting equipment.

Material performance that sustains accuracy

Made from aluminium‑magnesium alloy, the rule combines low mass with predictable mechanical behaviour: yield strength 110 kg/mm², tensile strength 47 kg/mm² and hardness HV 80. These properties reduce the risk of permanent deformation in everyday workshop use and help preserve reference surfaces after repeated mounting or light knocks. The alloy choice also simplifies handling and transport compared with heavier steel alternatives.

Practical details for integration into fixtures

Built‑in relief holes allow secure fastening to assembly tables, templates or jigs without compromising the reference edge. The specified parallelism 0.022 mm ensures that the opposing faces remain consistent over the length, which is vital for clamping and multi‑point supports. Delivered as a ready‑to‑install straightedge, it fits common fixture workflows in toolmaking, assembly and quality control applications.
