    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.
    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.

    4-Pin

    For easy tightening and loosening, these sockets have pins that grip the slotted sides on bearing nuts. These sockets require less clearance around bearings than standard hook spanner wrenches, so they’re good in tight spaces. Use them with a square-drive wrench handle or a ratchet wrench; they’re not for use with impact wrenches.

    1" Square Drive—3/4", 1", and 1 1/2" square drive size sockets require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.
