48H551 - Walter Square Key Stock - Industrial Machine Key Steel

Precision Power Transmission Components

Walter Key Steel is a premium-grade industrial key stock designed to meet the rigorous demands of maintenance, repair, and operations (MRO) professionals. In the world of power transmission, the integrity of the connection between a shaft and its mating component—be it a gear, pulley, sprocket, or coupling—is paramount. This key stock is manufactured from high-quality cold-drawn steel, ensuring superior dimensional accuracy and straightness. The precision drawing process results in a square profile with sharp corners and flat sides, allowing for a secure and precise fit within standard keyways without the need for excessive filing or fitting.

Engineered for reliability, Walter Key Steel provides the shear strength necessary to transmit torque effectively while protecting expensive machinery components. In the event of a torque overload, a properly sized key is often designed to shear before the shaft or gear teeth fail, acting as a mechanical fuse. This product offers a consistent grain structure and uniform hardness, making it predictable and dependable in critical applications. Whether you are assembling new machinery or performing emergency repairs on a production line, relying on high-quality key stock like this ensures that your equipment operates smoothly, with minimal vibration and backlash.

This stock is supplied in convenient lengths that can be easily cut to size using standard shop tools such as a hacksaw or abrasive cutoff wheel. Its surface finish is clean and free of heavy scale, facilitating easy installation and removal. For industrial environments where downtime equates to lost revenue, having a supply of Walter Key Steel ensures that maintenance teams can quickly fabricate replacement keys and return equipment to service with confidence.
