    Spline Opening

    These versatile wrenches turn a range of 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.
    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.

    Bit Screwdrivers

    Cushion Grip

    Don't lug around a toolbox full of drivers—just swap out the bit to drive multiple screw sizes and styles with one tool. The ultimate space savers, these bit screwdrivers are a smart solution for on-the-go jobs.
    Corrosion-Resistant Stainless Steel—With solid stainless steel construction, these screwdrivers have no coating that could flake off and damage the screw drive. They resist salt water and chemicals better than steel screwdrivers, but are not quite as strong.
    Cushion Grip—Made of soft plastic to make gripping and squeezing the handle more comfortable.

    Hex Shank

    Quick-Change Hex

    Shank

    Similar to Phillips bits, but with offset wings for a better grip. The bits in these sets are less likely to slip out of the screw head and damage the fastener.
    Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
    Steel—Best for dry environments, since moisture will cause these bits to rust.
