Kleffmann & Weese RS_304-8471, 500mm Engineer Square

The Kleffmann & Weese RS_304-8471 500 mm Engineer Square is a high-precision measuring tool designed for professional metalworking, fabrication, and quality inspection applications. The 500 mm blade length and 250 mm width meet DIN 875/2 standards for accuracy and reliability. Constructed from unhardened tool steel, it provides a stable reference edge in alignment, squaring and dimensional verification tasks.

Unique Features and Benefits of Choosing the Kleffmann & Weese 500mm Engineer Square

• 500 mm (0.5 m) blade length supports large-format workpieces with accurate squaring.
• 250 mm blade width enhances rigidity and reduces blade flex.
• Tool steel construction ensures long-term stability and flatness.
• Compliance with DIN 875/2 standard guarantees traceable accuracy.
• Unhardened body allows re-surfacing or calibration if needed.

Engineered for Precision Work

This engineer square is specifically built to provide a reliable 90° reference in metal and mechanical workshops. The large 500 mm blade allows alignment across full sheet widths, while the broad 250 mm width maintains perpendicularity without deflection. Its unhardened form permits surface grinding for calibration, making it ideal for inspection benches and tool-room setups where maintaining accuracy over time is essential.

Applicable Areas of the Product

• Checking the perpendicularity of large welded frames and assemblies.
• Setting up machine tool vices, table-din rails and layout plates.
• Verifying squareness on fabrication jigs and fixturing systems.
• Inspection work in quality labs for large volume production.
• Calibration reference tool for maintenance of measurement equipment and gauges.
