Turn sockets with a bit screwdriver.

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.

Keep bits from slipping. Insert a bit into the adapter, place a screw on the end of the bit, and slide the adapter sleeve over the screw. The sleeve retracts as the screw is driven. These adapters hold hex-shank bits (also known as insert bits) in powered tools.

Attach these adapters to square-drive tools.

These adapters are designed to withstand the high torque of impact drivers. They hold hex-shank bits (also known as insert bits).

Designed to withstand high torque and force, these adapters fit the square drive on impact wrenches. Use with hex-shank bits (also known as insert bits).

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

Convert a power screwdriver or impact driver into a versatile drill. Also known as adapt-a-drive, these chucks have a 1/4" hex shank that fits the hex drive in most power screwdrivers and impact drivers.

Drill extremely small holes with a drill press using these adapters. The shank fits into a collet or adjustable drill chuck, and the other end securely holds a wire gauge drill bit.
