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.

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.

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.

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

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.

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

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.

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.

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.
