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

When vertical space is tight or you need an extra twist on your socket, use these dual drive hex bit sockets. They work with a standard square drive tool and a box or open end wrench.

An extra-long Phillips bit allows these sockets to reach far-away fasteners. Use them where standard or stubby sockets can’t reach.

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

An opening at the tip of these sockets fits around the security pin, allowing you to drive tamper-resistant Torx Plus screws.

These sockets are made to withstand the high torque and force of impact tools.

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

Keep a convenient variety of drive styles and sizes of bit sockets on hand.

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

In addition to a standard square drive, the sockets in these sets have a hex-shaped base so you can use a ratchet wrench along with an open-end or box wrench for additional leverage.

Pivot the head of the sockets in these sets to access fasteners from an angle.

When vertical space is tight or you need an extra twist on your socket, use one of the dual-drive Phillips bit sockets in this set.

Use these sockets as an alternative to a screwdriver or L-key. They are made to withstand the high torque and force of impact tools.

Extra-long bits help you access hard-to-reach fasteners.

Strong and durable, these multipurpose bits are often used with power tools to install sheet metal screws.

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

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.

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

A retaining ring at the tip grips inside the recess to ensure screws won't slip off the bit.

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.

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 pentalobe and tamper-resistant Torx Plus screws.

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.

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.

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

Remove screws in hard-to-reach places. A spring-loaded sleeve guides bits onto the screw head and keeps them from slipping out.

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.

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.

Bits have a different size at each end.

The tip is shaped like an eight-pointed star.

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

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

These are also known as TP3® bits.

These bits are shaped like a 12-pointed star. They're also known as XZN bits.

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

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

Turn the screws found in Apple devices.

A three-winged tip fits triangular slotted screw recesses.

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.

These are also known as known as butterfly and Type G bits.

Assortments contain bits with multiple drive styles.

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

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.

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

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

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