A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects – usually rotary fasteners, such as nuts and bolts—or keep them from turning. The most common shapes are called open-ended spanner and ring spanner. Higher quality wrenches are typically made from chromium-vanadium alloy tool steels and are often drop-forged. They are frequently chrome-plated to resist corrosion and for ease of cleaning.

Wrenches and applications using wrenches or devices that needed wrenches, such as pipe clamps and suits of armor, have been noted by historians as far back as the 15th century. Adjustable coach wrenches for the odd-sized nuts of wagon wheels were manufactured in England and exported to North America in the late eighteenth and early nineteenth centuries.
