What is the primary function of a combination wrench?

• A. Turning hex and square nuts and bolts, the open end provides for faster turning.
• B. Measuring torque with high precision.
• C. Cutting threads on bolts.
• D. Bending metal to shape.

Answer: (A)

A combination wrench is designed for turning fasteners. The open end lets you engage and reposition quickly, which is handy in tight spaces and for rapid, repeated turning. The boxed (closed) end surrounds the fastener more fully, giving a tighter grip and allowing you to apply more torque with less risk of slipping or rounding off the corners. This combination makes it versatile for hex and square nuts and bolts, covering common sizes you’ll encounter. It doesn’t measure torque, cut threads, or bend metal, so its primary job is simply to turn fasteners efficiently.
