Strong and durable, these multipurpose bits are for use with bit screwdrivers. They are often used with power tools to install sheet metal screws.

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

The small-diameter shaft can access screws in narrow recessed holes.

An exterior stop collar prevents fasteners from being driven too deep. Use with soft material such as drywall, wood, and fiberboard.

Protect your stainless steel screws by using a stainless steel bit. If steel flakes off a standard bit and into the recess, it can lead to rust and contamination. These bits eliminate that risk.

Thread these bits directly into your driving tool for minimal wobble in assembly applications.

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

When you don't have exact alignment between the fastener and the bit, the ball end allows angled entry to turn screws in hard-to-reach areas. A retaining ring grips inside the recess to hold screws in place.

Protect your stainless steel screws by using a stainless steel bit. If steel flakes off a standard bit and into the recess, it can lead to rust and contamination. These bits eliminate that risk.

The toughest bits available, these withstand the shock and twisting force of impact drivers. Designed for screws with a square recess in the head, they are also known as Robertson bits.

Strong and durable, these multipurpose bits are for use with bit screwdrivers.

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.

These bits have an offset cross shape. They’re also known as ACR® bits.

These bits provide a secure grip on the Phillips/slotted combination-drive screws in electrical equipment.

The tip is shaped like an eight-pointed star.

These bits have a 4 mm HIOS shank. To fit in a 1/4" hex shank driver, use an adapter.

An opening at the tip accommodates the pin in the recess of tamper-resistant square screws.

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

Also known as Reed and Prince bits.

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.

While screws with a Square/Phillips combination drive can be turned with either a Square or Phillips bit, these make the best contact so you can apply high torque without slipping and stripping the recess. They are also known as Quadrex bits.

Also known as Polydrive bits.

Turn two drive styles with one reversible bit. Remove and replace to change the tip.

Turn screws that have the tamper-resistant asymmetrical drive exclusive to McMaster-Carr.

The toughest bits available, these withstand the shock and twisting force of impact drivers. A magnet holds the nut in place.

Because they make contact on the flat sides of fasteners rather than only on the corners, these magnetic bits significantly reduce slipping and stripping. They’re also known as lobular bits.

Assortments contain bits with multiple drive styles.

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

Also known as Bristol bits, these have a knurled-end shank that allows finger tightening. They can also be used with the included screwdriver.

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.

These bits are also known as nut setters.

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

A three-winged tip fits triangular slotted screw recesses.

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

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.

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

Use 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.

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.

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

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

Attach these adapters to square-drive tools.

Fit these small cases comfortably in your pocket.

Mount the magnetic base to walls, cabinets, and other steel surfaces.

Lock the bit into the chuck to prevent accidental disengagement.

Operate these tools like a standard bit driver and access hard-reach fasteners with the offset head. Insert a bit and a magnet holds it in place.

LEDs light the tip so you can use these tools in dark areas.

Drive screws four times faster than ratcheting alone. Grip the speed housing at the base of the shaft with one hand while turning the handle with the other. A magnet at the end of the shaft holds bits in place.

Also known as ESD-safe bit screwdrivers, the handle drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment.

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.

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.

When working in tight spaces, these short drivers fit where others can't. Bits have a different tip at each end and snap into the shaft, which is also a nutdriver.

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

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

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.

Create your own tool by attaching these shafts to a handle, or use 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.

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

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

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

The short bit on these sockets fits in spaces where height clearance is limited.

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

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