Choose the right hinge based on mounting style, clearance, leaf thickness, knuckle length, and other important dimensions.
Precision-Control Friction Hinges

Style 1 | Style 2 |
Change the resistance of these hinges by turning the screw. They hold lids, panels, and doors open without props, locks, or springs.
Acetal—Rigid and wear resistant, these hinges are a good choice for doors that are opened and closed frequently. They also have good chemical resistance and won’t soften when exposed to moisture.
430 Stainless Steel—Made of an economical stainless steel alloy, these hinges resist corrosion from mild chemicals and water. However, they won't hold up to long-term outdoor exposure like 304 stainless steel can.
Torque—When selecting a hinge to use with a lid, first find the torque force needed to move the lid. Multiply the weight of the lid (in pounds) by the distance between the hinge and the center of the lid (in inches). For example: if the lid weighs 3 lbs. and the distance between the hinge and the center of the lid is 12", the torque force is 3 lbs. × 12"= 36 in.-lbs. Divide the torque force by the number of hinges. For example, if using two hinges 36 in.-lbs. ÷ 2 = 18 in.-lbs. each.

Multi-Axis Friction Hinges

Move objects up, down, and all around—these hinges rotate 360° and tilt to any angle within their range. Mount them to equipment panels, carts, workstations, and vehicle trays.
430 Stainless Steel—Made of an economical stainless steel alloy, these hinges resist corrosion from mild chemicals and water. However, they won't hold up to long-term outdoor exposure like 304 stainless steel can.
Tilt Torque—When selecting a hinge, first find the torque force needed to move the panel. Multiply the weight of the panel (in pounds) by the distance between the hinge and the center of the panel (in inches). For example: if the panel weighs 3 lbs. and the distance between the hinge and the center of the panel is 12", the torque force is 3 lbs. × 12"= 36 in.-lbs.
