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

    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.
    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.

    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.

    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.
    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.
