Socket Adapters and Extensions

Socket Extensions

Extend your socket's reach.

Electrical-Insulating Socket Extensions

Insulated to protect against accidental contact with live electrical circuits, these extensions are tested to 1,000 volts to meet IEC 60900.

Nonsparking Socket Extensions

Made of aluminum-bronze, these extensions satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Wobble Socket Extensions

The square drive has a rounded shape that allows the extension to pivot inside the socket opening and turn it from an angle.

Flexible Socket Extensions

Bend these extensions around obstructions to turn hard-to-reach fasteners.

Secure-Hold Socket Extensions

Lock your socket into the extension to prevent accidental disengagement.

Adjustable Torque-Limiting Socket Adapters

Set a desired torque within the range.

Factory-Set Torque-Limiting Socket Adapters

Adapters are set to a specific torque and cannot be adjusted.

Square Drive Size Adapters

Convert from one square drive size to another.

Convertible Square Drive Size Adapters

Push the square drive through the adapter to change size.

Electrical-Insulating Square Drive Size Adapters

These adapters are insulated to protect against accidental contact with live electrical circuits. They are tested to 1,000 volts to meet IEC 60900.

Flex Socket Adapters

Pivot the head to access fasteners from an angle.

Ratcheting Socket Adapters

Change a standard wrench handle into a ratcheting wrench.

Hex Shank to Square Drive Adapters

Turn sockets with a bit screwdriver.

Angled Hex Shank to Square Drive Adapters

The angled shape lets you use your bit driver like a wrench.

Impact Socket Adapters and Extensions

Impact Square Drive Size Adapters

Convert from one square drive size to another.

Impact Magnetic Square Drive Size Adapters

A magnet holds the socket, making changes quicker.

Impact Socket Extensions

Attach to your socket for a longer reach.

Secure-Hold Impact Socket Extensions

Lock your socket into the extension to prevent accidental disengagement.

Impact Flex Socket Adapters

Pivot the head to access fasteners from an angle.

Impact Torque-Limiting Socket Adapters

Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached.

Impact Quick-Change Socket Adapters

Pull the collar to quickly attach and remove sockets.

Power Socket Adapters and Extensions

Hex Shank to Power Socket Square
Drive and Impact Square Drive Adapters

Use sockets with tools that accept hex shanks, such as impact drivers and power drills.

Flexible Power Socket Extensions

Bend these extensions around obstructions to access hard-to-reach fasteners.

Socket Sets

Impact Square Drive Size Adapter Sets

Convert from one square drive size to another.

Impact Socket Extension Sets

Attach to your socket for a longer reach.

Secure-Hold Impact Socket Extension Sets

Lock your socket into the extension to prevent accidental disengagement.

Impact Torque-Limiting Socket Adapter Sets

Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached.

Socket Extension Sets

Attach to your socket for a longer reach.

Square Drive Size Adapter Sets

Convert from one square drive size to another.

Ratchet Wrenches

A ratchet mechanism allows you to turn fasteners without removing and repositioning the wrench.

Screwdriver Bits and Adapters

Bit Adapters

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

Secure-Hold Bit Adapters

Lock your bit into the adapter to prevent accidental disengagement. 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.

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.

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 these adapters to hold hex-shank bits (also known as insert bits) in powered 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 Ratchet Wrenches

Attach these adapters to square-drive tools.

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.

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).

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 Assortments

Assortments contain bits with multiple drive styles.

Precise-Control Bit Assortments

The knurled shank on these bits allows finger tightening. They can also be used with the included screwdriver.

High-Torque Bit Assortments

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

Fabricating and Machining

Adjustable Collet Stops

Ensure parts don't push back into the collet while machining.

Drill Bit Shank Adapters for Power
Screwdrivers and Impact Drivers

For use in power screwdrivers and impact drivers that accept a 1/4" hex shank, each adapter holds a variety of round-shank drill bit sizes for quick tool changes.

Drill Bit Shank Adapters for Rotary Hammers

Adapt your rotary hammer to fit a variety of masonry drill bit shank types.

Changeable-Size SDS-Max-Shank Masonry
Core Drill Bits for Rotary Hammers

These bits allow you to easily switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling holes larger than 1 1/2" in diameter.

Changeable-Size Spline-Shank Masonry
Core Drill Bits for Rotary Hammers

These bits allow you to easily switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling holes larger than 1 1/2" in diameter.

5C Collet to Lathe Chuck Adapters

No need to break down a collet set up when a workpiece doesn't fit a 5C collet. Install one of these lathe chuck adapters in your 5C collet chuck or holder and its three jaws will securely grasp the workpiece.

Lathe Chuck to 5C Collet Adapters

When a job calls for a 5C collet, save time by using an adapter instead of removing your lathe chuck.
