27 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.

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.

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.

Open-End Wrenches

Round

Opening

Adjust fasteners in tight spots such as motor housings, HVAC systems, and under sinks when you can't get a grip from the top. Slip around nuts and bolts from the side, unlike box wrenches that require more space to fit over fasteners. These wrenches are ASME or DIN 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.

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

Black Phosphate-Coated Steel—The dark coating on these wrenches forms a rust-resistant barrier, making them good for wet areas. However, they won't hold up to salt water and chemicals. The coating is textured for a firm grip, even when your hands are greasy.

Round

Opening

Twist various sizes of 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.

Spline Ratcheting Combination Wrenches

Spline Opening

These versatile wrenches turn hex, 12-point, and spline fasteners. With more points of contact than 12-point openings, the spline-shaped box end gets a better grip on nuts and bolts and is less likely to round off corners. Rotate these wrenches without having to remove and reposition them. They're commonly used where you don't have enough space for full turns. To switch between loosening and tightening, flip them over.

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

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.

Sure-Grip Open-End Wrenches

12-Point

Sure-Grip

Opening

Get a firm hold on flare nuts and fittings to create leak-tight seals on tubing without cracking it. The heads on these wrenches have recessed corners to distribute turning force more evenly than standard wrenches, preventing stripping and slipping. They're well-suited for tight spots on refrigeration, brake, fuel, or hydraulic lines. Also known as flare-nut or line wrenches.

12-Point Sure-Grip Opening—These wrenches slide onto hex-head fasteners at more angles than those with hex sure-grip openings for quicker engagement. However, they’re more prone to slipping because they make less direct contact with the surfaces.

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

Changeable-Head Torque Wrenches

Change heads to use these tools as an open-end, box, square drive, or hex-key wrench. The handle and head combination you choose may have different maximum torque values. Do not exceed the lower value. The handles come with a calibration certificate, which includes test measurements that confirm accuracy.

You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.

L-Keys

The highest quality L-keys you can buy for tightening and loosening screws. Our L-keys are precision manufactured to tight tolerances for an exact fit.

Alloy Steel—These L-keys handle high torque without bending or breaking, so they’ll last a lifetime.

Short—A short long leg fits into tight spaces where you have less room to swing, making these ideal for confined areas.

Long—The most common option, these L-keys have a balanced length for everyday reach and torque.

Extra Long—Reach deep fasteners with the extra-long leg on these L-keys. Flip them around and grip the long leg with two hands for extra leverage to loosen stubborn screws.

Dual-Size 12-Point Impact Socket Sets


	Dual-Size View	12-Point Socket

Use one socket to switch between two fastener sizes. The spring-loaded innermost wall stays in place for smaller fasteners; push the socket onto a larger fastener and this wall slides out of the way.

With twice as many corners, 12-point sockets grab onto hex-drive fasteners more quickly than 6-point sockets. They also match the external 12-point screws commonly found in heavy duty vehicles such as bulldozers and excavators. Also known as double-hex sockets. These sockets are sturdier and have more give than manual-drive sockets, so they'll withstand the high torque and force of impact tools.
