The toughest bits available, these withstand the shock and twisting force of impact drivers.

When you don't have exact alignment between the fastener and the tool, the ball end allows angled entry to turn screws in hard-to-reach areas.

Protect your stainless steel screws by using a stainless steel bit. If steel flakes off a standard bit and into the recess, it can lead to rust and contamination. These bits eliminate that risk.

An opening at the tip accommodates the pin in the recess of tamper-resistant Torx screws. These are also known as pin-in-Torx bits.

The six rounded points fit the star-shaped recess of Torx-Plus screws. These bits have a similar profile to Torx but are not recommended for use with standard Torx screws.

The toughest bits available, these withstand the shock and twisting force of impact drivers.

The slightly tapered tip wedges into the screw recess for a secure hold. These are also known as Torx-Align bits.

An opening at the tip accommodates the pin in the recess of tamper-resistant Torx screws. These are also known as pin-in-Torx bits.

Sets include an assortment of keys. These simple tools turn fasteners from either end and reach into tight spots.

When a standard-tip key can't make good contact with the recess, a ball end allows angled entry to turn screws in hard-to-reach places.

A retaining ring at the tip grips inside the recess to ensure screws won’t fall off.

These plastic organizers store keys in slots marked with the size.

A ratchet mechanism turns fasteners more quickly than a standard bit driver. Insert a bit into the shaft and a magnet holds it in place.

LEDs light the tip so you can use these tools in dark areas.

Bits have a different tip at each end and snap into the shaft, which is also a nutdriver.

Choose a handle based on torque and change shafts to use a different size or drive style. Factory-set screwdrivers ensure you reach the same torque every time.

Sets include assorted keys with long shafts that reach into tight spots. The plastic-covered handles provide a good grip for your whole hand.

The assorted keys in these sets have a long shaft for more reach and a short shaft for more torque when turning fasteners.

The assorted keys in these sets have a small T-handle that prevents you from generating too much torque when turning a fastener. They are often used to install carbide inserts in cutting tools.

These assorted keys have a retaining ring on the tip that grips inside the recess to hold screws in place. Often used to install carbide inserts in cutting tools, these keys have a small T-handle that prevents you from generating too much torque when turning a fastener.

Extra-long bits allow access to hard-to-reach fasteners.
