These constant torque cartridges enable users to easily position doors, display screens and other mounted components and hold them securely at any desired angle – fully opened, fully closed, or anywhere in between.These cartridges are designed specially for applications where customers need to integrate constant torque functionality into a molded assembly.The ST-8P and larger ST-11P feature an overmolded design that encapsulates and hides the hinge for enhanced aesthetic value.The small diameter of both cartridges enables designers to use them with great flexibility that is difficult to achieve with a nut and bolt, and a customizable holding torque provides the right "feel" for a wide range of application needs.
