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-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.

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.

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

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.

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.

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

Double Open-End Wrenches


		Round Opening	Square Opening

Switch between two different-sized fasteners without swapping out your wrenches. The two heads save you time, while reducing the number of tools you need to keep on hand. Drop forged for added strength, these wrenches 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.

Square Opening—Grip square-head fasteners to securely tighten or loosen them.

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.

Corrosion-Resistant Wear-Resistant 420 Stainless Steel—Containing more carbon than 17-4 PH stainless steel, these wrenches stand up to abrasion and impacts for years of use without breaking or warping. They won’t rust in wet and outdoor environments, plus they resist mild acids.

Corrosion-Resistant High-Strength 17-4 PH Stainless Steel—The strongest stainless steel open-end wrenches we offer withstand force without deforming. They won’t rust in wet and outdoor environments, plus they resist mild acids.

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.

Tight-Clearance Angled Open-End Wrenches

Round

Opening

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.

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

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.

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.

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.

Miniature Open-End Wrenches


	Hex Opening

Take on precision tasks with extra slim heads. These wrenches are just the right size for assembling electronics, building models, and repairing small appliances.

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.

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.

Sure-Grip Open-End Wrenches


Hex Sure-Grip Opening	12-Point Sure-Grip Opening

Round 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.

Hex Sure-Grip Opening—Avoid rounding off the corners of hex-head fasteners. These wrenches won't slip, even when nuts and bolts are rusted or damaged, since they grip the sides rather than the corners.

Hex Sure-Grip and Round Openings—One end snugly grips sides rather than corners of hex-head fasteners so they won’t slip, even when nuts and bolts are rusted or damaged. The other end spreads force evenly with round edges to prevent stripping your fasteners.

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.

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

Tight-Clearance Angled Open-End Wrench Sets


Round Opening	Hex Opening

Keep a collection of sizes handy to turn thin, awkwardly placed fasteners tucked away in confined spaces. Use the 60° or 75° 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.

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

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.

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.

Offset Head—The head and handle are angled, making it easier to maneuver around obstacles to reach fasteners in tight spots.

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.

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

Open-End Wrenches for Army-Navy Fittings

Hex Opening

Securely tighten AN (Army-Navy) fittings to create reliable high-pressure connections, such as on hydraulic lines. These aluminum wrenches have an opening with recesses in the corners, which form a deep hold on fittings to prevent marring. They also have shorter handles than standard open-end wrenches to keep you from over-torquing. All of them are color coded by drive size for you to quickly spot and grab the right one. Also known as AN wrenches.

Tight-Clearance Open-End Wrench Sets

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.

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.

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