Square Drive Adapters for Power Tools
Attach your square-drive sockets to drills, powered screwdrivers, and other tools that accept a hex shank. Not for use with impact tools.
Adapters with ball detent, the standard retainer style, have a spring-loaded ball that holds the socket in place, allowing you to slide it on and off quickly. Adapters with a pin style retainer provide a more secure hold than ball detent style because you have to depress the pin to attach or remove the socket. Also called positive locking.

Impact Magnetic Square Drive Size Adapters
A magnet holds the socket, making changes quicker. These adapters convert from one square-drive size to another. They’re sturdier and have more give than manual-drive adapters, so they'll withstand the high torque and force of impact tools.
Adapter with 3/4" square drive requires a retaining ring on the female end for attachment to tools that have a hole- or hole-and-ring style socket retainer.

Continuous-Duty Square Drive Adapters for Power Tools
Use these adapters to connect sockets to impact wrenches and other power tools—they’re designed to tolerate continuous use in high-volume production and assembly. They’re hardened to resist wear from repeated use, lasting longer than standard impact adapters. They convert square-drive sockets so they can attach to power drills, impact drivers, and other tools that accept a hex shank.
Secure-Hold Bit Adapters
With Magnetic
Quick-Change Chuck
Quick-Change
Chuck for Hex Shank Bit
Lock your bit into the adapter to prevent accidental disengagement. Use hex-shank bits (also known as insert bits) in drills and powered screwdrivers. These adapters have a groove in the shank to fit in a power-tool chuck.
To secure a bit in adapters with quick-change chuck, pull back on the chuck to insert the bit and then push it forward to lock the bit place.
To secure a bit in twist-lock adapters, tighten the knurled end.
Adapters that have nonmagnetic bit holders won’t attract loose metal parts and shavings.

Flexible Bit Adapters
Bend these adapters up to 90° to access hard-to-reach fasteners. Use hex-shank bits (also known as insert bits) in drills and powered screwdrivers.
Tight-Clearance Bit Adapters
The head is angled 90° to drive fasteners in tight spaces. Use the pivoting handle to guide and steady the bit. These adapters hold hex-shank bits (also known as insert bits) and power bits in drills and powered screwdrivers.

Screw-Holding Bit Adapters
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 hex-shank bits (also known as insert bits) in drills and powered screwdrivers.

Screw-Guiding Bit Adapters
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. Use hex-shank bits (also known as insert bits) in drills and powered screwdrivers.
Plastic sleeve is clear so you can see that the bit is making contact.
Bit Adapters for Impact Drivers
These adapters are designed to withstand the high torque of impact drivers. They have a groove in the shank to fit in the tool’s chuck and accept hex-shank bits (also known as insert bits) as well as hex-shank bits for power tools.

Bit Assortments
These assortments contain general-purpose bits.
Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.
Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.
