Replace nuts on 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.

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

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

Pair these tools with your ratchet wrench to get more leverage.

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

Turn 5-point tamper-resistant nuts and bolts often found on water and gas valves.

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

Turn off the main supply of water or gas at the point it enters your facility.
