Combination wrenches are used to tighten or loosen fasteners, fittings, and more. The open end is more versatile as it can fit different types of nuts and bolt heads. The box end provides a secure grip on fasteners in tight spaces and prevent bolts from rounding or breaking.
Are combination wrenches the same as open end wrenches?
Combination wrenches include both an open end and a box end for hard-to-reach places. These hand tools are often available in 7-pc to 30-pc combination wrench sets to fasten nuts and bolts of different shapes and sizes depending on your needs.
