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.

Note: Air 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.

Built for durability, these high-performance tools handle the demands of high-volume production and tough maintenance applications. They have a positive-locking socket retainer that 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.

Pin-style socket retainer has a pin that fits into a matching hole in the socket.

Hole-style socket retainer requires a retaining ring (included).

Use these wrenches for medium-volume production, general maintenance, and construction applications. 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.

Pin-, and hole-style socket retainers (also called positive locking) provide a more secure hold than ring-style retainers. Pin-style retainer has a pin that fits into a matching hole in the socket. Hole-style retainer requires a retaining ring.

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.
