Carpenter Square c.k tools T3533 09 225 mm hardened tempered steel

Carpenter Square c.k tools T3533 09 225 mm hardened tempered steel is a compact, durable 90° square engineered for carpentry and woodworking tasks. Made from hardened, tempered steel, the 225 mm blade and stock provide a consistent reference for checking squareness, marking right angles and aligning edges and joints in both workshop and on-site environments. The tool’s solid construction resists wear and maintains accuracy through repeated use.

Advantages

The hardened, tempered steel construction offers long-lasting edge retention and resistance to deformation, ensuring the square remains true under regular use. Its compact 225 mm size balances precision and portability, making it easy to carry in a tool pouch or place on a benchtop. The simple two-piece design provides a stable 90° reference without moving parts, reducing potential sources of error and maintenance needs.

Key specifications

How to use

Place the stock of the square firmly against the edge of the workpiece so the stock sits flush. With the stock held steady, draw a line along the blade to transfer a precise 90° layout line or use the inside face of the blade to check the squareness of assembled parts. For measuring, align the blade with the surface to mark distances from the edge. Ensure contact with the workpiece remains consistent and avoid levering the tool to prevent deformation. Store the square in a dry place when not in use.

Recommendations

Regularly inspect the square’s mating faces for nicks or burrs and clean before use to preserve accuracy. Use a light protective oil if storing for extended periods to reduce surface corrosion. For critical layout work, verify the square against a known reference before marking.
