Ratchet Wrenches

A ratchet mechanism allows you to turn fasteners without removing and repositioning the wrench.

Adjustable-Length Ratchet Wrenches

The shaft on these wrenches extends and locks at set increments.

Flex-Head Wrench Handles

Access fasteners in tight spots by pivoting the head to an optimal angle. These nonratcheting wrench handles are also known as breaker bars—they’re long enough for you to get the leverage needed to break stuck fasteners free.

Flex-Head Wrench Handles with Tether Ring

Loosen stubborn fasteners while working up high—these wrench handles clip to a carabiner or lanyard (not included) to prevent drops.

Sliding T-Style Wrench Handles

Position the head anywhere along the handle.

Adjustable Torque Wrenches

Set the desired torque and the wrench indicates when it's reached with an audible click and an impulse in the grip.

Dial Torque-Measuring Wrenches

A main pointer on the dial shows torque as it’s being applied and a memory pointer indicates the maximum torque reached.

Striking Square Drive Wrenches

Take a swing and hit these wrenches with a hammer to generate the extra torque you need to break stuck fasteners free. Also known as slugging wrenches.

Air-Powered Impact Wrenches

Loosen stubborn fasteners—these wrenches operate at full torque counterclockwise to break stuck bolts free.

Built to withstand tough environments, these wrenches have steel or titanium housings to protect them if they fall.
