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.

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. These adapters hold hex-shank bits (also known as insert bits) in powered tools.

Flexible Bit Adapters

Bend these adapters up to 90° to access hard-to-reach fasteners. Use them to hold hex-shank bits (also known as insert bits) in powered tools.

Bit Adapters for Ratchet Wrenches

Attach these adapters to square-drive tools.

Secure-Hold Bit Adapters for Ratchet Wrenches

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

Bit Adapters for Impact Drivers

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

Bit Adapters for Bit Screwdrivers

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

Bit Adapters for Impact Wrenches

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).

Bit Adapters for Rotary Hammers

Insert these adapters into your SDS-drive rotary hammer to use it with hex-shank bits (also known as insert bits).

Torque-Measuring Bit Adapters

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.

Torque Screwdrivers

Torque Screwdriver and Bit Sets

These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter.

Torque Screwdrivers

Set the desired torque and the driver indicates when it's reached.

Static-Control Torque Screwdrivers

Also known as ESD-safe screwdrivers, the handle drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. When set torque is reached, these drivers slip to disengage and prevent overtightening.

Changeable-Shaft Torque Screwdriver Sets

Set includes a handle and six shafts. Remove and replace the shaft to use a different size or drive style.

Changeable-Shaft Torque Screwdrivers

Choose a handle based on torque, and a shaft with the size you need.
