Pipe Wrenches

Nonmarring Pipe Wrenches

Also known as monkey and auto wrenches, these grip large fasteners and other flat objects.

Round-Grip Nonmarring Pipe Wrenches

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.

Nonsparking Nonmarring Pipe Wrenches

Made of aluminum-bronze that is Factory Mutual approved, these wrenches inhibit sparking and are nonmagnetic and corrosion resistant. They are also known as railroad wrenches.

Pipe Wrenches

Grip pipe and conduit as well as tighten and loosen fittings.

Nuts for Pipe Wrenches

Heel Jaws for Pipe Wrenches

Hook Jaws for Pipe Wrenches

Springs for Pipe Wrenches

Quick-Adjust Pipe Wrenches

Open and close the jaws with one hand. Press the lever and slide the bottom jaw to the desired position; tension keeps it in place.

Self-Adjusting Pipe Wrenches

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

Nonsparking Pipe Wrenches

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

Internal Pipe Wrenches

Insert into a pipe or fitting and turn—the wrench grips the walls for easy installation and removal without marring the outside of the pipe.

Torque-Limiting Pipe Wrenches

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

Combination Adjustable/Pipe Wrenches

Reverse the movable jaw to convert from a smooth-jaw adjustable wrench to a serrated-jaw pipe wrench.
