Assortments contain bits with multiple drive styles.

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

A retaining ring grips inside the recess to hold screws in place. These bits have a ball end that allows angled entry to drive screws in hard-to-reach areas.

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.

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

Ribs forged into the wings of these bits grip the screw recess to reduce stripping. They're also known as ACR® bits.

These bits are also known as nut setters.

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.

Designed for the fasteners used in electronics assembly, the tip of these bits has slightly sharper corners than Phillips style.

A three-winged tip fits triangular slotted screw recesses.

Also known as Bristol bits, these have a knurled-end shank that allows finger tightening. They can also be used with the included screwdriver.

Also known as Robertson bits these are designed for screws with a square recess in the head.

Fit these small cases comfortably in your pocket.

Store a variety of sizes and styles of bits and adapters in one compact tray.
