About Torque Tools

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.

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-, hole-, and ring-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- and ring-and-hole-style retainers require 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.

Tight-Clearance Air-Powered Screwdrivers

An angled handle makes it easier to drive fasteners in tight spaces. These direct-drive tools start turning the bit as soon as the operator pulls the trigger. They provide a high level of control over fastening but do not have any built-in mechanism for preventing overtightening or limiting torque. Since pressure is not required for the screwdriver to turn the bit, they're good for fastening through compressible materials.

Note: Air tools require lubrication to operate properly.

Air-Powered Screwdrivers

Positive Clutch Drive

Direct Drive

Screwdrivers with positive clutch drive are the best choice for fastening applications where torque control is not critical. These tools require the operator to pull the trigger and apply pressure to the screw before the bit will turn. The clutch slips as soon as pressure is lifted or the maximum torque of the tool is reached.

Screwdrivers with direct drive start turning the bit as soon as the operator pulls the trigger. These tools provide a high level of control over fastening but do not have any built-in mechanism for preventing overtightening or limiting torque. Since pressure is not required for the screwdriver to turn the bit, they're good for fastening through compressible materials.

Air-Powered Tap Wrenches

Powered by compressed air, these tap wrenches thread holes faster and with less effort than manual tap wrenches. They’re often used in place of manual tap wrenches when threading many holes and hard materials. Compared to drill presses and CNC machines, which are stationary, these wrenches are portable so you can take them to the part that needs to be threaded. To remove chips from your hole, press the reverse button to rotate the tap counterclockwise. Switch different taps in and out of the chuck when your tap is worn down or you need a new size. Use with machine tool taps and tapping lubricants for best results.
