Everyone has seen a hinge, but how many people have taken the time to consider the parts that make up this important device? For that matter, have you ever considered how these components combine to make different types of hinges function?
Here at iHinge.com, hinges are our specialty. We’ve compiled a comprehensive list of the various parts of a hinge and how they work together.
Parts of a hinge
Leaf: The flat part of a hinge that extends away from the barrel and revolves around the pin.
- Overall leaf length: Length of the leaf measured parallel to its pin.
- Leaf width: The measurement from the pin to the leaf edge.
- Open leaf width: The measurement of the leaf perpendicular to its pin.
Pin: The rod that divides the two leaves, which pivot around it. Pins are made up of a rod and a barrel.
Paint clearance: The space that allows the opposite leaf to curl inward. It also allows for paint to not be damaged when the hinge curls.
Barrel/knuckle: A hollow section of a hinge that the pin goes through.
Joint length: The length of a single joint section.
Barrel length: The length of all the joints put together.
Leaf thickness: The thickness of the hinge leaves: .35 and under is considered light.
Side play: The amount of movement possible between the leaves and pin.
End play: The amount of leaf axial movement.
Pitch: Dimension of any point on a knuckle to the adjacent barrel on one leaf.
Now that you’re familiar with all the different parts of a hinge, we hope you can gain a better understanding of how our stainless-steel hinges for home and marine applications are superior to the standard versions you’d find in a big box store.
