What is the primary usage of a bar clamp?

A bar clamp is primarily designed for clamping large wood sections together, making it an essential tool in woodworking and construction projects. Its design features long arms with a fixed jaw on one end and a sliding jaw that can be adjusted to accommodate various widths of material. This allows the user to apply even pressure across the surface being joined, which is particularly important when working with larger pieces of wood that require stability while glue sets or when fastening other components together.

In contrast, while a bar clamp can hold small pieces in certain situations, it is not specifically designed for that purpose, as smaller clamps, like spring clamps or C-clamps, are typically more suitable for such tasks. The functions related to securing threads and cutting material do not align with the intended use of a bar clamp, as they involve different tools and techniques altogether.
