Prism pair M318.281 — cast, 90° accuracy 0.016 mm (Metav IndustryLine)

The Prism pair M318.281 is a cast angle-prism set for supporting and aligning cylindrical components during inspection, setup and clamping operations.

• 90° alignment with 0.016 mm accuracy
• Hardened special steel for dimensional stability
• Compliant with DIN 876/1 standard
• Supports shafts Ø5–40 mm for inspections

Accuracy that speeds up inspection and set-up

The cast prisms are designed to provide a repeatable datum for cylindrical parts, with a declared angular precision of 90° and a positional tolerance of 0.016 mm. This level of control reduces the need for repeated checks and shortens setup time during batch inspections. The declared accuracy is a measurable performance parameter that supports consistent referencing and reliable alignment in production and quality control tasks, turning uncertainty into a verifiable result.

Robust construction for stable measurement support

Manufactured in hardened special steel, the pair offers high stiffness and resistance to local deformation, which preserves geometry under routine handling. Compliance with DIN 876/1 ensures the geometry and finishing meet recognised workshop standards, aiding interchangeability and predictable behaviour on the bench. The cast design provides a broad contact surface that dampens small positional errors, making the set particularly suitable where dimensional stability and contact integrity are essential.

Practical benefits for workshop and inspection workflows

By providing a stable support for cylindrical components, the prisms simplify repeatable clamping and improve the efficiency of measurement processes. The geometry is optimised for shaft support in the Ø5–40 mm range, enabling quick positioning for caliper checks and visual inspection. Traceable manufacturing and consistent geometry help reduce rework and support a smoother workflow between machining and quality assurance departments, reinforcing operational confidence in routine tasks.
