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.

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.

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.

Ratcheting Combination Wrenches

12-Point

Opening

Turn nuts and bolts without having to remove and reposition these wrenches. They're commonly used where you don't have enough space for full turns. To switch between loosening and tightening, flip them over.

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.

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

Sure Grip Wrench Heads


Wrench and Socket Extension Not Included	12-Point Sure-Grip Opening

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 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.

12-Point Sure-Grip Opening—Wrenches with a 12-point sure-grip opening quickly position on hex fasteners.

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.

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