Definition & Meaning of "combination wrench"

What is a "combination wrench"?

A combination wrench is a hand tool used for tightening or loosening nuts and bolts. It has two ends: one with a box end and the other with an open end. The box end is a closed loop that fits around the nut or bolt, providing a firm grip, while the open end fits over the fastener, allowing for faster movement. Combination wrenches are versatile, often used in mechanical and repair work, as the two different ends offer options for working in tight spaces or on fasteners of varying sizes.
