A butt hinge is made up of two leaves with three or more pins, knuckles, and a barrel that is curved. The knuckle, also known as the barrel, is the hinge's main pivot point, and is normally secured to the leafs using fasteners such as screws.
One of the primary advantages of butt hinges is their capacity to accommodate heavier loads than other hinges. This is due to their larger knuckle, which provides more support for the leafs. In addition hinges with butts have a greater capacity for expansion and contraction, making them more resistant to the effects of extreme temperatures.
Butt hinges are also installed in recessed surfaces. They aren't visible when the door opens or closes. This gives a smoother appearance and a more refined design. However, they could require routing for an even finish.
Butt hinges come with a disadvantages. The friction they create can, for example wear down the hinges over time. To avoid this it is recommended to regularly clean and lubricate the hinges. This will prevent friction from tearing the knuckles and ensure they function smoothly.
Some hinges that use butt hinges have a ball bearing between the knuckles to reduce friction. These are ideal for doors that see a lot of use. They are also available with a pin that is fixed, which is ideal for doors that cannot be opened with the removal of the pin.
Other kinds of butt hinges include a plain bearing with grease, which reduces friction by permitting the hinge to move with less force. These hinges are ideal for light-weight applications like cabinet doors. They are also available with spinned ends to ensure that the pin stays in place.
Butt hinges are typically employed in residential settings, however they are also used in commercial and industrial applications.

Butt hinges are available in various sizes and loads to fit various door sizes and weights. The type of hinge you choose will be determined by the purpose for which it is used and the desired degree of performance and durability. The load-bearing capacity of a hinge is based on the amount of force that is applied to the hinge, and the length of time that it is exposed to that pressure. For heavy-duty applications, a heavier-duty hinge will be required.
Flag hinges are an extremely common type of hinge for doors. They are suitable for a variety of applications and sizes. They tend to be smaller and lighter than other types of hinges, which makes them ideal for use on doors with a lightweight construction.

With the fixing jig drill these holes prior to the time you attach the hinge plate to the sash so that it is flush with the profile. Ensure that the screws furthest from the hinge body are anchored to steel reinforcing and plastic instead of the wood of the sash, in order to prevent damage to the sash or frame.
