Bit Sets

Bit Assortments

Assortments contain bits with multiple drive styles.

Bit Assortments for Impact Drivers

The toughest bits available, these withstand the shock and twisting force of impact drivers.

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.

Precise-Control Bit Assortments

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

Hex Bit Sets

Ball-End Screw-Holding Hex Bit Sets

A retaining ring grips inside the recess to hold screws in place. These bits have a ball end that allows angled entry to drive screws in hard-to-reach areas.

Ball-End Hex Bit Sets

When you don't have exact alignment between the fastener and the tool, the ball end allows angled entry to turn screws in hard-to-reach areas.

Screw-Holding Torx Bit Sets

The slightly tapered tip wedges into the screw recess for a secure hold. These are also known as Torx-Align bits.

Torx Bit Sets

Slotted Bit Sets

Phillips Bit Sets

Slip-Resistant Phillips Bit Sets

Ribs forged into the wings of these bits grip the screw recess to reduce stripping. They're also known as ACR® bits.

6-Flute Spline Bit Sets

Fastener-Holding Nutdriver Bit Sets

A magnet holds the nut in place.

Nutdriver Bit Sets

These bits are also known as nut setters.

Torq-Set® Bit Sets

These bits have an offset cross shape.

Pozidriv® Bit Sets

JIS Bit Sets

Designed for the fasteners used in electronics assembly, the tip of these bits has slightly sharper corners than Phillips style.

Torx-Plus Bit Sets

The six rounded points fit the star-shaped recess of Torx-Plus screws. These bits have a similar profile to Torx but are not recommended for use with standard Torx screws.

Square Bit Sets

Also known as Robertson bits these are designed for screws with a square recess in the head.

Drilled Spanner Bit Sets

Use with screws that have two drilled holes.

Tri-Groove Bit Sets

Grip the indentations on the head of tri-groove fasteners.

Tamper-Resistant Torx Bit Sets

An opening at the tip accommodates the pin in the recess of tamper-resistant Torx screws. These are also known as pin-in-Torx bits.

Tamper-Resistant Hex Bit Sets

An opening at the tip accommodates the pin in the recess of tamper-resistant hex screws. These are also known as pin-in-hex or pin-in-socket bits.

Tri-Wing® Bit Sets

A three-winged tip fits triangular slotted screw recesses.

Changeable-Shaft Screwdrivers

Electrical-Insulating Changeable-Shaft Screwdriver Sets

An insulated handle and shafts protect against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet IEC 60900.

Changeable-Shaft Screwdriver Sets

Remove and replace the reversible shaft to change the tip of the tool. Sets include a handle and multiple shafts.

Compact Changeable-Shaft Ball-End Screwdriver Sets

The ball-end tip allows angled entry to turn screws in hard-to-reach areas. These tools are a scaled-down version of standard changeable-shaft screwdrivers, They're shorter, slimmer, and easy to take with you. Remove and replace the shaft to change the tip size.

Compact Changeable-Shaft Screwdriver Sets

A scaled-down version of standard changeable-shaft screwdrivers, these tools are shorter, slimmer, and easy to take with you. Remove and replace the shaft to use a different tip size.

Adjustable Torque Screwdrivers

Torque Screwdriver and Bit Sets

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

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.

Ball-End Driver Shaft Sets

These assorted shafts attach to a handle or can be used 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.

Ceramic Changeable-Shaft Adjustment Screwdriver Sets

Ceramic Changeable-Shaft
Adjustment Screwdriver Sets

Use these ceramic-tipped screwdrivers for adjusting sensitive electronic components such as capacitors and resistors. They're completely nonconductive and nonmagnetic so there's no risk of short-circuiting or creating magnetic interference. Remove and replace the shafts to use a different size or drive style.

Bit Socket Sets

Hex, Torx, Phillips, and Slotted Bit Socket Assortments

Keep a convenient mix of hex, Torx, Phillips, and slotted bit sockets on hand.

Hex Bit Socket Sets

Extended-Reach Ball-End Hex Bit Socket Sets

Extra-long bits allow access to hard-to-reach fasteners.

Ball-End Hex Bit Socket Sets

The ball end allows angled entry when you don't have exact alignment between the socket bit and fastener.

Tamper-Resistant Torx Bit Socket Sets

These sockets are also known as pin-in-Torx bits.

Extended-Reach Torx Bit Socket Sets

Extra-long bits allow access to hard-to-reach fasteners.

Torx-Plus Bit Socket Sets

Torx Bit Socket Sets

Tamper-Resistant Hex Bit Socket Sets

These sockets are also known as pin-in-hex or pin-in-socket bits.
