Moore & Wright 4004 Engineer's Square Grade B 100mm (4in)

Moore & Wright 4004 Engineer's Square Grade B 100mm (4in)

Precision, Durability, and Reliability are the hallmarks of the Moore & Wright 4004 Engineer’s Square. Designed for engineers, machinists, and precision craftsmen, this square delivers an uncompromising level of accuracy that is essential in any workshop or laboratory setting.

Key Features

• Grade B Accuracy: The square is manufactured to Grade B standards, ensuring a tolerance of ±0.05 mm (±0.002 in). This precision makes it ideal for aligning and checking right angles in machining operations.
• 100 mm (4‑inch) Length: A compact yet substantial size that balances portability with sufficient length for most measurement tasks.
• High‑Quality Steel Construction: Made from high‑strength steel, the square resists deformation and maintains its shape even under repeated use.
• Precision Ground Edges: Both edges are ground to a 0.001 mm (0.00004 in) tolerance, guaranteeing that the square’s faces remain perfectly perpendicular.
• Corrosion‑Resistant Finish: The steel is treated with a protective coating that resists rust and corrosion, extending the life of the tool in damp or dusty environments.

Applications

The 4004 Engineer’s Square is indispensable for tasks that demand exact right angles. Typical uses include:

• Machining: Setting up milling and turning operations, verifying the squareness of machine tables, and checking the alignment of workpieces.
• Metal Fabrication: Cutting, bending, and welding metal sheets with precise angular relationships.
• Woodworking: Ensuring that joints and cuts are perfectly square in cabinetry, furniture making, and carpentry projects.
• Surveying & Drafting: Establishing reference lines and verifying orthogonal measurements on technical drawings.

Design and Ergonomics

The 4004’s sleek profile allows for easy handling, while its balanced weight distribution ensures that the square can be held steady without fatigue. The flat, smooth surface provides a reliable reference point for aligning tools and fixtures.

Maintenance Tips

• Cleaning: After each use, wipe the square with a dry cloth to remove dust or metal shavings that could affect accuracy.
• Storage: Keep the square in a dry environment; avoid prolonged exposure to moisture to prevent corrosion.
• Inspection: Periodically check for any signs of wear or deformation. If the edges become dull, re‑ground them to restore precision.
