There's no adjustment nut or button on these wrenches—a spring-loaded hinge automatically closes the top jaw around pipe.

Made of materials that are Factory Mutual approved, these wrenches inhibit sparking and are nonmagnetic and corrosion resistant.

The jaws grip most round surfaces, even highly polished objects. Push down on the wrench and pull the handle toward you—the jaws will tighten around the workpiece.

Use one end as a traditional pipe wrench and the other to loosen valve wheels. These are also known as engineers’ pipe wrenches.

Turn the end of the handle to set torque, and the wrench makes an audible click when it reaches the setting.

These tools have the heavy duty handle and adjustment mechanism of a pipe wrench and the smooth jaws of a traditional adjustable wrench.

Using your ratchet wrench as a handle, access hard-to-reach caps and plugs or grip objects of almost any shape.

Turn the adjustment screw and squeeze the handle to lock the chain in place; press the lever to release.

The nonmarring strap grips plastic pipe, tubing, hand wheels, filters, and objects with highly polished surfaces.

While some wrenches require you hold the strap, these have a shackle that keeps the strap closed for extra turning force and quick adjustment.
