Strong and durable, these multipurpose bits are for use with bit screwdrivers. They're designed for screws with a square recess in the head and are also known as Robertson bits.

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 exterior stop collar prevents fasteners from being driven too deep. Use with soft materials such as drywall, wood, and fiberboard.

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.

These screwdrivers have a soft, contoured handle that provides comfort and the best possible grip for achieving maximum torque.

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.

Sets include assorted drivers with an insulated handle and shaft that protect against shock from accidental contact with live electrical circuits. They are tested to 1,000 volts to meet IEC, EN, or ASTM standards.

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.

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.
