Air-Powered Ratchet Wrenches

Ball-Detent-Style Socket Retainer

Faster than manual ratchet wrenches, these ratchet wrenches run on air to turn fasteners quickly. They have a steel head that protects the ratchet mechanism from bumps and drops in the shop. Socket changes are quick—the ball-detent style socket retainer lets you pull one socket off and push another one on. All operate at maximum torque in both clockwise and counterclockwise directions. Air-powered tools require lubrication to run properly.

Wrenches with backlash protection won’t kick back once a fastener is tightened, keeping your knuckles from banging into nearby objects. These wrenches put a lot of force on the socket, so you’ll need to use them with an impact socket (sold separately).

Sealed-Head Air-Powered Ratchet Wrenches

Ball-Detent-Style Socket Retainer

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.

Air-Powered Impact Wrenches

D-Handle Grip

Ring-Style Socket Retainer

Hole-Style Socket Retainer

Loosen stubborn fasteners—these wrenches operate at full torque counterclockwise to break stuck bolts free. You can also use them clockwise within their working torque range to tighten fasteners more quickly than with manual wrenches. Use these wrenches with impact sockets only. Air-powered tools require lubrication to operate properly.

D-handle grip wrenches are heavier than straight or pistol grip wrenches, so you need to use two hands to deliver their full power.

Ring-style socket retainers are good for quick socket changes—just pull the socket off the retainer and push on another one.

Ring-and-hole and hole-style socket retainers hold sockets more securely than ring-style retainers and require a retaining ring. Hole-style socket retainers are also known as positive locking retainers.

Heavy Duty Air-Powered Impact Wrenches

Pistol Grip

D-Handle Grip

Ring-Style Socket Retainer

Hole-Style Socket Retainer

Built to withstand tough environments, these wrenches have steel or titanium housings to protect them if they fall. Use them when you need high force to turn fasteners. To break stuck fasteners free, apply full torque counterclockwise. To drive fasteners, turn them clockwise within the working torque range. These wrenches can only be used with impact sockets. Air-powered tools require lubrication to operate properly.

Ring-style socket retainers make it easy to quickly change sockets. Just pull the socket off the retainer and push on another one.

Ring-and-hole style and hole-style socket retainers require a retaining ring (not included).
