    When locked into the chuck, these bits won't budge. Use these screwdrivers for high-torque applications, such as driving long screws into dense material.
    Pull back the chuck to insert a bit in the magnetic holder; push it forward to lock it in place. Bits store neatly inside the handle so you won't lose them.

    Tight-Clearance Flexible Bit Screwdrivers

    Image of Product. Front orientation. Screwdrivers. Tight-Clearance Flexible Bit Screwdrivers.
    A flexible shaft bends around obstacles to access screws in hard-to-reach places. These screwdrivers snake into compact machinery where a rigid tool wouldn't fit. However, they may wobble if you crank them too hard. Attach a bit (not included) to drive a variety of screws with a single tool.
    Quick-Change Chuck—Holds bits more securely than a magnet, so they don't accidently slip off. Pull back the chuck to insert a bit; push the chuck forward to lock the bit in place.

    Image of Product. Front orientation. Socket Extensions. Strong-Hold Impact Socket Extension Sets.
    Also known as positive-locking extensions, these extensions hold sockets in place with a ball that only retracts when you pull the collar down. Designed to prevent accidental detachment, they lock to your socket more securely than other extensions. They’re thicker and less brittle than manual extensions, so they withstand the high torque and force of impact tools. They flex slightly when force is applied, so they’re less likely to break. Each set includes three common extension lengths to tackle a variety of jobs.

    Lock your socket into the extension to prevent accidental disengagement. Locked in place by a ball that retracts when the collar is pulled (also called positive locking), these sockets hold more securely than our standard extensions. These extensions are thicker than standard extensions, and also have enough give to flex under high force without breaking. This makes them a good choice for use with impact tools.
