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.

Ball-Detent-Style Socket Retainer

Use these tools for general shop applications. They have a ball-detent-style socket retainer that allows quick socket changes—pull the socket off the retainer and push on another one. Wrenches operate at full torque in both clockwise and counterclockwise direction. 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.
