Deep-Offset Striking Box Wrenches

The head is offset 45° to provide clearance for reaching over obstructions. Also known as slugging wrenches, strike the handle with a hammer to break stuck fasteners free.

Ratcheting Box Wrenches

12-Point Opening

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

Turn Required to Ratchet—The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.

Strikable Open-End Wrenches

Round

Opening

Don't wrestle with stuck fasteners. Strike the handle with a hammer to break them free. Designed to take the hits, these wrenches are drop forged for added strength and will be part of your toolbox for life. Also known as slugging wrenches.

Round Opening—The rounded edges spread force evenly to prevent stripping your fasteners. Use them on hex-head fasteners.

Steel—Best for dry environments since moisture will cause these wrenches to rust.

Also known as slugging wrenches, strike the handle with a hammer to break stuck fasteners free.

Wrench Heads


Wrench and Socket Extension Not Included

Reach nuts obstructed by a fluid line or other barrier with these wrench heads. Connect them to your socket extension and ratchet wrench to turn fasteners where clearance is limited from both the top and side. You can also attach one directly to your ratchet wrench to convert it into an open-ended ratcheting wrench. Also known as crowfoot wrenches.

Combination Wrenches

12-Point

Opening

Your go-to wrenches for routine maintenance. With two different ends, you need fewer tools to tighten and loosen nuts and bolts. The open end slides onto the side of fasteners for adjustments in tight spots. When nuts and bolts won't budge, the box end fully encircles them to apply maximum torque. Drop forged for added strength, these wrenches will be part of your toolbox for life.

12-Point Opening—The most common opening, these wrenches work on hex and 12-point nuts and bolts. They slide onto hex heads at more angles than 6-point fasteners for quicker engagement, but they're more likely to slip when you apply more torque.

Chrome-Plated Steel—The most popular finish, these wrenches won't rust or chip. Although they withstand moisture better than black oxide, they don't hold up to harsh chemicals as well as stainless steel.

Black-Oxide Steel—The dark, matte coating protects these wrenches from wear and won't flake off. They offer minimal corrosion resistance, though, so they're best for dry environments.

Dull—With a textured finish, these wrenches won't slip out of your hands, even when greasy or oily.

Impact Hex Bit Sockets


	For Hex Drives

These sockets are made to withstand the high torque and force of impact tools.

Compatible Retaining Ring ID—Sockets that list a compatible retaining ring ID require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.

Tight-Clearance Open-End Wrenches

Round

Opening

Twist thin fasteners in cramped spots where other wrenches are too bulky. With a head and handle about half as thick as standard wrenches, it's easier to grip nuts found in electrical enclosures and small machinery. These wrenches are ASME certified—they handle more torque than run-of-the-mill alternatives and precisely fit fasteners so they don't round them off. Drop forged for added strength, they will be part of your toolbox for life. Also known as check nut or service wrenches.

Round Opening—The rounded edges spread force evenly to prevent stripping your fasteners. Use them on hex-head fasteners.

Black-Oxide Steel—The dark, matte coating protects these wrenches from wear and won't flake off. They offer minimal corrosion resistance, though, so they're best for dry environments.
