    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.

    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 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.
