Plier vs. Wrench — What's the Difference?
By Fiza Rafique & Urooj Arif — Updated on April 23, 2024
Pliers grip and manipulate materials by using two metal levers joined at a pivot point, while wrenches apply torque to turn objects like nuts and bolts using a fixed or adjustable jaw.

Key Differences
Pliers are designed with a pair of metal levers that pivot at a fulcrum to multiply force, allowing for gripping, twisting, and cutting of materials. Whereas, wrenches are tools that feature a handle with a fixed or adjustable jaw designed specifically for turning nuts, bolts, or other similar objects by applying torque.
Pliers come in various types, such as needle-nose, slip-joint, and wire cutters, each specialized for different tasks like reaching into narrow spaces, gripping different sized objects, or cutting wires. On the other hand, wrenches also vary in type, including combination, socket, and Allen wrenches, each suited for specific tasks and sizes of bolts or fasteners.
The working mechanism of pliers involves the user squeezing the handles together to apply force at the jaws, effectively transferring energy to manipulate the object held. In contrast, wrenches involve positioning the jaw around an object and turning the handle to apply rotational force, which is ideal for tightening or loosening.
Pliers often feature teeth on their jaws for better grip on objects, making them suitable for pulling or twisting tasks. Whereas, wrench jaws may have smooth or slightly serrated surfaces depending on the type, designed to fit around objects like nuts and bolts to provide leverage without slipping.
While pliers can be used in a variety of applications, including electrical and plumbing work, to grip and manipulate materials, wrenches are predominantly used in mechanical and assembly applications to apply torque and turn objects.
