    6-Point

    Opening

    With a range of drive sizes and lengths, these wrench sets are your go-to 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.
    6-Point Opening—Avoid rounding off the corners of hex fasteners. These wrenches won't slip, even when nuts and bolts are rusted or damaged, since they grip the sides rather than the corners.
    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.
    Industrial—Made in the U.S. from high-strength steel or stainless steel, these wrenches are built to last. They’re indispensable for daily maintenance and repair.
    Value—Fill out your tool kit for a few dollars per wrench. Typically imported, these cost-friendly sets are the right choice for occasional maintenance.
    Dull—With a textured finish, these wrenches won't slip out of your hands, even when greasy or oily.
    Polished—The smooth surface is easy to wipe clean of grime. The mirror-like finish lends a high-end look to any toolkit.
    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.
    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.

    Spline Opening

    These versatile wrenches turn hex, 12-point, and spline fasteners. With more points of contact than 12-point openings, the spline-shaped box end gets a better grip on nuts and bolts and is less likely to round off corners. Rotate these wrenches without having to remove and reposition them. They're commonly used where you don't have enough space for full turns. To switch between loosening and tightening, flip them over.
