Ratchet Wrenches and Handles

Screwdriver-Style Socket Handles

Turn sockets from above when there's not room to swing a standard wrench handle.

Ratcheting Screwdriver-Style Socket Handles

The ratcheting mechanism turns sockets quickly.

Flexible Screwdriver-Style Socket Handles

Bend around obstructions to turn hard-to-reach fasteners.

Flex-Head Wrench Handles

Pivot the head for access to fasteners in tight spots.

Adjustable-Length Flex-Head Wrench Handles

Extend the shaft for additional length.

Cushion-Grip Flex-Head Wrench Handles

A rubber coating provides a comfortable grip.

L-Style Wrench Handles

The L shape provides clearance when reaching over obstructions.

Sliding T-Style Wrench Handles

Position the head anywhere along the handle.

Ratchet Wrenches

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

Cushion-Grip Ratchet Wrenches

The handle is covered in rubber for a comfortable grip.

Tapered-Handle Ratchet Wrenches

Also known as a construction or spud handle, wrenches use the pointed end to align bolt holes.

Replaceable-Head Ratchet Wrenches

When the ratchet head becomes worn or damaged, change it out for a new one.

Fast-Driving Ratchet Wrenches

Twist the grip to rapidly turn a socket before final tightening or to remove a fastener once loosened. The handle also swings like a traditional ratchet wrench.

Sealed-Head Ratchet Wrenches

A gasket seals in permanent lubrication and keeps out dirt, dust, and moisture.

Quick-Release Ratchet Wrenches

No need to pull the socket off the tool—push a button to release.

Adjustable-Length Ratchet Wrenches

The shaft on these wrenches extends and locks.

Electrical-Insulating Ratchet Wrenches

Insulated to protect against accidental contact with live electrical circuits, these wrenches are tested to 1,000 volts to meet IEC 60900.

Nonsparking Ratchet Wrenches

Made of aluminum-bronze, these wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Fingertip Ratchet Wrenches

Turn sockets in the most confined spaces.

Tight-Clearance Ratchet Wrenches

Rather than teeth, these wrenches use a series of rollers to engage the ratchet, enabling work in the tightest of spaces. Also known as silent ratchets, they don't make the traditional click sound when turned.

Bolt-Through Ratchet Wrenches

Bolts and threaded rod pass through these wrenches when used with bolt-through sockets.

Offset Flex-Head Ratchet Wrenches

The 20° offset head provides clearance when reaching over obstructions.

Quick-Release Flex-Head Ratchet Wrenches

No need to pull the socket off the tool—push a button to release.

Flex-Head Ratchet Wrenches

Pivot the head to access fasteners in tight spots.

Speeder Handles

Fasten quickly with these crank-style handles.

Torque Wrenches

Flex-Head Adjustable Torque Wrenches

Pivot the head to access fasteners in tight spots.

Nonsparking Torque Wrenches

Made of beryllium copper, these wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Click-Style Factory-Set Torque Wrenches

When the set torque is reached, these wrenches signal with an audible click and an impulse in the grip.

Data-Recording Torque-and-Angle
Measuring Wrenches

The most advanced torque wrenches we offer, these tools store and recall up to 1,500 torque and angle measurements.

Torque-Measuring Wrenches

Measure with an accuracy of ±2%.

Box Wrenches

Ratcheting Box Wrenches

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

Two-Head Ratcheting Box Wrenches

Ratchet mechanisms allow you to turn fasteners in tight spaces without removing and repositioning the tool.

Two-Head Deep-Offset Ratcheting Box Wrenches

The 25° offset heads give you additional clearance to turn hard-to-reach fasteners.

Box Wrenches

Changeable-Head Torque Wrenches

Change heads to use these tools as an open-end, box, square drive, or hex-key wrench.

Torque Screwdrivers

Changeable-Shaft Factory-Set Torque Screwdrivers

Choose a handle based on torque and change shafts to use a different size or drive style. Factory-set screwdrivers ensure you reach the same torque every time.

Square-Drive Torque Screwdrivers

Attach a socket to the 1/4" square drive tip to turn hex nuts and hex head screws. When set torque is reached, these drivers signal with an audible click.

Square Drive Torque-Measuring Screwdrivers

Attach a socket to the 1/4" square drive tip. These tools have a dial that shows how torque measurements change as you turn the driver. Use to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners.

Ratchet Handles

Ratcheting action allows for quick adjustment to machinery and valves in tight spaces. All of these handles have a straight, open socket head for long shafts to pass through.
