Hinge Pins

Do you have to use the same material for the hinge and the pin?

Most hinges share a common material in the pin and body.

Why might you choose a different material for the pin?

The material need not be the same, but certain metals have what is called Dielectric interference. When this occurs, contact between those different metals can cause corrosion to happen much quicker. For this reason, when a pin is different than the body of the hinge, it is usually an inert material like brass.

Pins are made of different material to address concerns such as friction or strength. In some cases, pins are heat treated to add strength or coated to reduce friction. Pins can be lubricated with a grease fitting or ride on a bearing.

Do the hinge pins have to be a certain diameter?

Pin diameter is a critical part of the hinges function. It determines how easily the hinge opens and closes as well as determines the hinges ultimate strength.

If the diameter of the pin is larger what does that mean for the hinge?

Larger diameter pins mean a stronger hinge.

Are there any benefits to one over the other?

The hinge pin is really selected based on experience and the specific application. Most all hinges are designed to a safety factor of 4 to 6 times the rated load.
