About Torque Tools

Trigger Speed Control

Push-to-Start Speed Control

Lever Speed Control

Set torque and the clutch slips when it’s reached, causing the tool to stop turning the fastener. To set torque, turn the adjustment collar or screw and then verify the torque setting with a torque tester.

Note: Air tools require lubrication to operate properly.

High-Precision Air-Powered Torque Screwdrivers

Push-to-Start Speed Control

Lever Speed Control

The motor shuts off when the set torque is reached to provide the most torque control of any air-powered screwdriver. To set torque, turn the adjustment collar or screw and then verify the torque setting with a torque tester.

Torque-Limiting Air-Powered Wrenches

1/4" Square Drive

3/8" Square Drive

Pin-Style Socket Retainer

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.

Air-Powered Impact Wrenches

Pistol Grip

Straight Grip

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).
