20 mm Wrenches | McMaster-Carr

With a range of drive sizes and lengths, these wrench sets are your go-to 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.

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.

Industrial—Made from high-strength steel or stainless steel, these wrenches are built to last. They’re indispensable for daily maintenance and repair.

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

Polished—The smooth surface is easy to wipe clean of grime. The mirror-like finish lends a high-end look to any toolkit.

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.

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.

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.

Polished—The smooth surface is easy to wipe clean of grime. The mirror-like finish lends a high-end look to any toolkit.

Wrench Head Sets


Wrench and Socket Extension Not Included	Wrench Head Set with Plastic Clip Rail

Reach nuts obstructed by a fluid line or other barrier with the wrench heads in these sets. Connect them to a 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.

Sure Grip Wrench Head Sets


Wrench and Socket Extension Not Included

Grip more of your fastener head with these wrench heads. They have a hex or 12-point opening with more surface area than rounded wrench heads, so they make more contact with fasteners for a better hold. Also known as flare-nut crowfoot wrenches or line wrenches, they're often used with flared tube fittings as well as fuel and hydraulic lines. Connect them to a 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.

Tight-Clearance Angled Open-End Wrenches

Hex Opening

Stop struggling with thin, awkwardly placed fasteners tucked away in confined spaces. Use the 60°, 75°, or 80° angled head to reach around obstacles and apply more force without constant repositioning. The two heads save you time and reduce the number of tools you need to keep on hand. Also known as ignition wrenches.

Hex Opening—Snugly grip the sides rather then the corners of commonly used hex-head fasteners so they won't slip, even when the nuts and bolts are rusted or damaged.

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

Retaining Rings

Remove and install dual wheels on trucks and trailers with the sockets in these sets. The sockets are extra deep for use with Budd wheels, so you can remove both the nut and the stud with a single socket. Sets include sockets for hex drives to access lug nuts and sockets for square drives to turn the threaded shafts on inner wheels. All are impact sockets, made to withstand the high torque and force of impact tools. Use them 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.
