One of the major advantages of butt hinges is their ability to take on heavier loads than other hinges. This is due to their larger knuckle that provides more support for the leafs. Butt hinges are more resistant to extreme temperatures since they have more capacity to expand and contract.

As with other hinges, butt hinges are available in a range of sizes and load-bearing capacity to fit different door sizes and weights. The application and desired degree of durability and functionality will determine the type of hinge to choose.
