What is Key Steel?

Keysteel, often referred to as key bar or key steel, is a type of precision-machined metal commonly used in engineering and manufacturing. This material serves as the component that fits into the keyway of a shaft and hub, ensuring power transmission and preventing rotation between parts. Keysteel is available in both metric and imperial sizes, and can be found in different finishes, such as self-colour and bright zinc plated, to suit a wide range of applications.

• Manufacturing process: Cold-drawn or precision-ground to tight tolerances.
• Supplied condition: Bright finish, straightened, and ready for machining.
• Common forms: Flat bars, square bars, and rectangular strips.

Unlike ordinary carbon steels, Key Steel is produced to exacting standards that guarantee high tensile strength, impact resistance, and dimensional accuracy.
