The Characteristics of a Standard Friction Hinge

The side-hung defender standard 16-inch / 16mm stack friction hinge is perfect for your window and door hardware needs. It is a high-quality, durable hinge that meets and exceeds all industry standards. When choosing a hinge, the material it is made of is important. Hinges must be strong enough to resist the torque of doors, panels, and flaps.


Standard friction hinges (constant torque or positioning) are pure mechanical components that keep an object in a fixed position. They are used in various products, including monitors in laptops and industrial applications, special suitcases, office equipment, safety equipment, lids, arms, seat rests, etc. To work efficiently, these hinges require precision clips, shaft components, and a proprietary lubricant.

They can also be customized and designed to meet specific torque-strength requirements. One-way hinges, which have resistance on only one side, two-way hinges with equal damping in both directions or a mix of the two, can all be used in custom designs. Customizability allows for variations in lubricant viscosity, construction material, and temperature tolerance to meet critical needs in medical, rugged, or hazardous environments. Brass is a very flexible and corrosion-resistant copper and zinc alloy. Its high machinability makes it an ideal material for producing friction hinges. It is durable and provides a pleasing aesthetic appearance.


A friction hinge, also known as a position control hinge, uses a mechanism built into it that generates resistance to pivoting motion. These mechanisms include curl type, disk type, and pipe-type systems. The amount of resistance can be varied. These hinges can hold lids, doors, windows, and panels in place for easy access. They prevent spring back, hard slamming, and unexpected shutting. These hinges are available in many sizes and materials, including bronze. Bronze is a corrosion-resistant metal with an appealing aesthetic appearance and good machinability. These hinges are ideal for marine use, where saltwater exposure is common. They also provide a consistent torque over a flat range of movement, which helps keep the door or panel position constant. They are also available in adjustable torque models and feature concealed mountings for a clean presentation. In addition, these hinges are tested for corrosion to ensure they have high durability. They are excellent for boat hatches, electronics doors, glove boxes, and smaller anchor lockers.


Torque hinges are used in various applications and environments, so they must be durable enough to withstand constant movement. They must also have a pleasing appearance and resist acidic or corrosive substances. The type of metal chosen is important because it impacts the durability of the hinge. Hard metals are more durable than soft ones. Brass and bronze are good choices for friction hinges because they resist corrosion from saltwater and have a bright appearance. Friction hinges can be adjusted by using a set screw. The adjustment can be made to a desired position or angle, allowing the hinge to remain in that position when force is applied. This type of hinge is called a free stop or friction torque positioning hinge and is great for items such as lids, displays, doors, and windows. A mechanical detent can be added at the closing point of the hinge to eliminate spring back.

Corrosion resistance

Corrosion resistance is an important feature for hinges outdoors or in harsh environments. The metals that make friction hinges vary in hardness, rust resistance and strength, so selecting the right hinge for your specific application is important. The hinge should be made of stainless steel for long-lasting durability and corrosion protection. Capabilities include design, engineering, reverse engineering, machining, fabrication & finishing services. Products serve a variety of applications, including laptop computers, cameras and enclosures.
