    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.
    Corrosion-Resistant Wear-Resistant 420 Stainless Steel—The most corrosion-resistant wrenches we offer. Stronger than other types of stainless steel, they'll withstand years of use without breaking or warping.
