Torque-Limiting Air-Powered Wrenches
Set torque and the wrench will prevent you from exceeding it. Also known as nutrunners, these tools are commonly used in assembly applications. They have a pin-style (also called positive locking) socket retainer that fits into a matching hole in the socket and provides a secure hold. Wrenches operate at full torque in both clockwise and counterclockwise direction. Use with impact sockets only. Air-powered tools require lubrication to operate properly.

Sealed-Head Air-Powered Ratchet Wrenches
Built to last, these wrenches have an enclosed steel head that seals lubrication in and dirt, dust, and moisture out to protect the ratchet mechanism. Since they’re air powered, these wrenches turn fasteners more quickly than handheld wrenches. They have a ball-detent-style socket retainer for quick socket changes—pull the socket off the retainer and push on another one. Wrenches operate at full torque in both clockwise and counterclockwise directions. Air-powered tools require lubrication to operate properly.

Light Duty Air-Powered Impact Wrenches
These tools are suitable for general shop, maintenance, and automotive work. Wrenches operate at full torque in both clockwise and counterclockwise direction. Use with impact sockets only. Air-powered tools require lubrication to operate properly.
Ring-style socket retainer allows quick socket changes—pull the socket off the retainer and push on another one.
Ring-and-hole style socket retainer (also called positive locking) provides a more secure hold than ring-style retainers and requires a retaining ring.
