Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine 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.

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.

A magnet holds the nut in place.

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.

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

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

Grip the indentations on the head of tri-groove fasteners.

Use with screws that have two drilled holes.

Fit these small cases comfortably in your pocket.

Mount the magnetic base to walls, cabinets, and other steel surfaces.
