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

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

Remove screws in hard-to-reach places. A spring-loaded sleeve guides bits onto the screw head and keeps them from slipping out.

A wide tip makes good contact in shallow and coated screw recesses, such as those filled with paint.

Thread these bits directly into your driving tool for minimal wobble in assembly applications.

These bits provide a secure grip on the Phillips/slotted combination-drive screws in electrical equipment.

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

While screws with a square/Phillips combination drive can be turned with either a square or Phillips bit, these make the best contact so you can apply high torque without slipping and stripping the recess. They are also known as Quadrex bits.

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

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

The knurled shank on these bits allows finger tightening. They can also be used with the included screwdriver.

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

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

Operate these tools like a standard bit driver and access hard-reach fasteners with the offset head. Insert a bit and a magnet holds it in place.

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.

Drive screws four times faster than ratcheting alone. Grip the speed housing at the base of the shaft with one hand while turning the handle with the other. A magnet at the end of the shaft holds bits in place.

An insulated handle and shaft protect against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet EN 60900 and IEC 60900.

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

Keep a convenient mix of hex, Torx, Phillips, and slotted bit sockets on hand.
