A three-winged tip fits triangular slotted screw recesses.

These bits have an offset cross shape.

Use hex-shank bits (also known as insert bits) in powered tools.

The head is angled 90° to drive fasteners in tight spaces. Use these adapters to hold hex-shank bits (also known as insert bits) in powered tools.

A magnetic ring at the end of the adapter holds flat-head screws in place to ensure good contact between the bit and screw. Use these adapters to hold hex-shank bits (also known as insert bits) in powered tools.

Lock your bit into the adapter to prevent accidental disengagement. These adapters attach to square-drive tools.

Eliminate the need for multiple bulky tools with these bit adapters. At less than 3 inches long, these compact adapters convert ¼” bit screwdriver handles and ¼” bits into torque screwdrivers so you can fasten to a specific torque.

Use a 4 mm bit in a bit driver that's designed for 1/4" bits.

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

Keep these caddies in your tool drawer or take them with you.

Create your own tool by attaching these shafts to a handle, or use with socket wrenches and power tools. They have a ball end that allows angled entry to make good contact with the recess when a standard-tip shaft can’t.

A ratchet mechanism allows you to drive fasteners when there's little space to move the handle.

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.

Insert a bit into the shaft and a magnet holds it in place.

Bits are held in place with a retaining ring or set screw rather than a magnet, so the tool won't attract loose metal parts and shavings.

Also known as ESD-safe bit screwdrivers, the handle drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment.

Bend the shaft around obstructions to reach fasteners that standard and offset screwdrivers can’t.

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

Adjust the nosepiece to set the depth and prevent fasteners from being driven too deep. These drivers are good for use with soft materials such as wood, fiberboard, drywall, and insulation board. They are powered by rechargeable batteries.
