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

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.

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

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.

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 slightly tapered tip wedges into the screw recess for a secure hold. Also known as Torx-Align 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.

Use with screws that have two drilled holes.

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

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 pentalobe and tamper-resistant Torx Plus 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.

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

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

Also known as Reed and Prince 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.

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

The tip is shaped like an eight-pointed star.

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.

A three-winged tip fits triangular slotted screw recesses.

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

These are also known as TP3® bits.

Turn hex nuts and cap screws.

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.

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

A magnet holds the nut in place.

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

These bits have an offset cross shape.

Use with screws that have two drilled holes.

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.

A three-winged tip fits triangular slotted screw recesses.

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

Lock your bit into the adapter to prevent accidental disengagement. These adapters hold 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.

Lock your bit into the adapter to prevent accidental disengagement. These adapters attach to square-drive tools.

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.

Use a 4 mm bit in a bit driver that's designed for 1/4" bits.

Fit these small cases comfortably in your pocket.

Keep these caddies in your tool drawer or take them with you.

Bits are held in place with a retaining ring or set screw rather than a magnet, so the tool won't attract loose metal parts and shavings.

Insert a bit into the shaft and a magnet holds it in place.

A ratchet mechanism turns fasteners more quickly than a standard bit driver. Insert a bit into the shaft and a magnet holds it in place.

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