Product Description

Square and Rectangular keys are relatively simple to manufacture and install, typically produced through processes like cold heading and stamping. They have three main styles: with rounded ends at both sides, with flat ends at both sides, or with one flat end and one rounded end. Square and Rectangular keys are suitable for applications where higher torque transmission is required, commonly used in heavy machinery and gearboxes. The key design requires proper orientation during installation to ensure they function as intended.
