What is the primary purpose of a joggle in metalwork?

The primary purpose of a joggle in metalwork is to allow clearance for a sheet or an extrusion. A joggle is a technique used to create a slight offset or bend in a metal component which enables it to fit within a space that otherwise would be too narrow or obstructed. This is particularly useful in components where two pieces must overlap or be connected but cannot be positioned flush due to design constraints.

In practice, joggles are commonly utilized in aviation and automotive manufacturing, where precise fitting and tolerances are critical. By creating a joggle, fabricators ensure that parts can be assembled without interference, maintaining the functionality of the assembly.

Other options touch on different aspects of metalwork but do not encompass the primary function of joggles. While increasing structural integrity, enhancing aesthetic appeal, and reducing weight are important considerations in metalwork, they do not accurately describe the specific utility of a joggle in accommodating space and fit within assemblies.
