Break stuck screws free using screwdriver bits. Strike the end of the handle with a hammer to turn the bit and tighten or loosen fasteners.
Connect these powerful tools to your shop air. They hammer as they rotate to drive screws quickly, even through thick or dense material.
These tools deliver powerful rotational blows to maximize torque and drive screws quickly, even through thick or dense material.
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.
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.
Remove screws in hard-to-reach places. A spring-loaded sleeve guides bits onto the screw head and keeps them from slipping out.
The small-diameter shaft can access screws in narrow recessed holes.
The toughest bits available, these withstand the shock and twisting force of impact drivers.
Ribs forged into the wings of these bits grip the screw recess to reduce stripping. They're also known as ACR® bits.
A wide tip makes good contact in shallow and coated screw recesses, such as those filled with paint.
An exterior stop collar prevents fasteners from being driven too deep. Use with soft material such as drywall, wood, and fiberboard.
Strong and durable, these multipurpose bits are often used with power tools to install sheet metal screws.
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.
The slightly tapered tip wedges into the screw recess for a secure hold. Also known as Torx-Align bits.
Strong and durable, these multipurpose bits are for use with bit screwdrivers.
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.
A retaining ring at the tip grips inside the recess to ensure screws won't slip off the bit.
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.
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.
These are also known as TP3® bits.
These bits provide a secure grip on the Phillips/slotted combination-drive screws in electrical equipment.
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.
The tip is shaped like an eight-pointed star.
An opening at the tip accommodates the pin in the recess of tamper-resistant pentalobe and tamper-resistant Torx Plus screws.
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.
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.
An opening at the tip accommodates the pin in the recess of tamper-resistant square screws.
Use with screws that have two drilled holes.
These bits are shaped like a 12-pointed star. They're also known as XZN bits.
Ribs forged into the wings of these offset-cross-shaped bits grip the screw recess to reduce stripping. They are also known as ACR® bits.
Also known as Polydrive bits.
These are also known as known as butterfly and Type G bits.
Also known as Reed and Prince bits.
These bits have an offset cross shape. They’re also known as ACR® bits.
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.
Strong and durable, these multipurpose bits are for use with bit screwdrivers. They're designed for screws with a square recess in the head and are also known as Robertson bits.
An exterior stop collar prevents fasteners from being driven too deep. Use with soft materials such as drywall, wood, and fiberboard.
Grip the indentations on the head of tri-groove fasteners.
A three-winged tip fits triangular slotted screw recesses.
Turn screws that have the tamper-resistant asymmetrical drive exclusive to McMaster-Carr.
Turn the screws found in Apple devices.
A magnet or retaining ring 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.
The toughest bits available, these withstand the shock and twisting force of impact drivers. A magnet holds the nut in place.
Turn hex nuts and cap screws.
Assortments contain bits with multiple drive styles.
These bits are also known as nut setters.
A magnet holds the nut in place.
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.
The slightly tapered tip wedges into the screw recess for a secure hold. These are also known as Torx-Align bits.
Designed for the fasteners used in electronics assembly, the tip of these bits has slightly sharper corners than Phillips style.
These bits have an offset cross shape.
Also known as Robertson bits these are designed for screws with a square recess in the head.
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).
These adapters are designed to withstand the high torque of impact drivers. They hold hex-shank bits (also known as insert bits).
Also known as impact drivers, use these tools with impact sockets to break frozen bolts and screws free. Strike with a hammer to tighten and loosen fasteners.
Use these wrenches for medium-volume production, general maintenance, and construction applications.
These tools are suitable for general shop, maintenance, and automotive work.
Built for durability, these high-performance tools handle the demands of high-volume production and tough maintenance applications.
Convert from one square drive size to another.
A magnet holds the socket, making changes quicker.
Pivot the head to access fasteners from an angle.
Pull the collar to quickly attach and remove sockets.
Prevent overtightening that can damage fasteners. These adapters spring back slightly when the set torque is reached.
Use sockets with tools that accept hex shanks, such as impact drivers and power drills.
