Prism Pair M318.251 – 90° hardened special steel, 75 mm

The Prism Pair M318.251 is a precision V-support pair designed for stable locating and inspection of cylindrical workpieces in clamping and measuring setups.

• Hardened special steel construction
• Precision 90° V-surface for consistent seating
• Suitable for shafts Ø5–40 mm

Accurate seating for cylindrical inspection

The pair provides a 90° V-surface machined to DIN 876/0 tolerances, delivering an accuracy of 0.008 mm that supports repeatable positioning in quality control and set-up operations. The precision V-profile concentrates contact lines on the workpiece so that run-out and concentricity checks become more reliable; this means fewer measurement variations and a lower risk of rework when integrating the prisms into inspection fixtures. The hardened special steel body resists deformation under moderate clamping loads, preserving the seating geometry over prolonged use.

Stable, transportable geometry for workshop use

Each prism measures 75 x 40 x 40 mm (L x W x H) and weighs 1.6 kg, giving a balance of mass and handling convenience that suits both bench-top inspection and intermittent machining support. The compact block design provides a low centre of gravity and a firm base for bench vices or fixture plates; the inherent stiffness reduces bounce and micro‑movement during manual operations. The robust finish and hardened core extend service life in a production environment while simplifying routine set-ups and repeat measurements.

Workflow compatibility and practical benefits

Designed as a standard support for cylindrical parts, the pair accepts shafts from Ø5–40 mm, making it versatile across small to medium-diameter components commonly found in toolmaking and production lines. The geometric stability facilitates quick referencing during adjustment, speeding up fixturing and reducing idle machine time. Integration with common clamping devices and measuring sequences is straightforward: the prisms act as a deterministic datum for run-out checks, alignment and visual inspection, offering a pragmatic combination of precision and operational efficiency.
