Set & Hold With Constant Torque Hinges
Torque hinges, also known as friction hinges, have a holding feature that sets them apart from the standard hinge. These hinges rely on internal friction between the leaf and the pin to resist movement and hold their position. Like the screen of a laptop computer, this allows a door or lid to open smoothly and then remain in a set position without opening or closing inadvertently.
Some friction hinges are adjustable, allowing you to tighten or loosen the torque based on feel. The constant torque hinge has a predetermined static torque; the benefit of these hinges is consistency. Constant torque hinges have been rigorously tested and are guaranteed to maintain consistent torque performance (± 20% of their specification) over a minimum 25,000 cycle lifetime. Made from high-quality die-cast zinc, these parts allow for the choice of higher torque options than adjustable versions.
