A Square Key is a standardized mechanical component that transmits torque and prevents relative motion between rotating components. Square keys are designed to fit into a corresponding keyway or keyseat, which is a slot or groove machined into a shaft or hub. The keyway has a square profile that matches the shape of the square key.Attributes:• Offer strength and durability.• Helps maintain alignment and stability in mechanical systems.Applications:A Square Key is used in mechanical systems where torque transmission and secure positioning are required.
