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. Another option is the constant torque hinge which has a predetermined static torque that cannot be modified. The benefit of these non-adjustable hinges is consistency. These parts have been rigorously tested and are guaranteed to maintain consistent torque performance (± 20% of specification) over a minimum 25,000 cycle lifetime.

Made from high-quality die cast zinc material, these parts allow for the choice of higher torque options than the adjustable versions. In addition to the symmetric torque hinges, where torque is the same in both directions, asymmetric options are also available, which requires a different torque to open the hinge than to close the hinge. This is intended for applications where it may be desirable for the door to open easily, but then be held open with a stronger force.

These hinges are available with different sizes, finishes, and hole styles to fit your exact OEM application. All Sierra Pacific constant torque hinges have smooth, quiet operation over a 270° opening angle without any observable spring-back or free-play over the lifetime of the part. Custom specifications for life cycle, torque rating, or any other feature are quotable for high volume projects.
