Screwdrivers

Ultra-Grip Screwdrivers

These screwdrivers have a soft, contoured handle that provides comfort and the best possible grip for achieving maximum torque.

Ultra-Grip Screwdriver Sets

Sets include an assortment of drivers with soft, contoured handles that provide comfort and the best possible grip for achieving maximum torque.

Ball-End Screwdriver Sets

The assorted drivers in these sets have a ball end that allows angled entry to turn screws in hard-to-reach areas.

Ball-End 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.

Electrical-Insulating Screwdriver Sets

Sets include assorted drivers with an insulated handle and shaft that protect against shock from accidental contact with live electrical circuits. They are tested to 1,000 volts to meet IEC, EN, or ASTM standards.

Electrical-Insulating Screwdrivers

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 IEC, EN, or ASTM standards.

Screwdrivers for Stainless Steel Screws

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

Tight-Clearance Ratcheting Bit Screwdrivers

A ratchet mechanism allows you to drive fasteners when there's little space to move the handle.

Ratcheting Bit Screwdrivers

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.

Bit Screwdrivers

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

Electrical-Insulating Bit Screwdrivers

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.

Reversible-Bit Screwdriver/Nutdrivers

Bits have a different tip at each end and snap into the shaft, which is also a nutdriver.

Adjustable-Length Screwdriver Sets

Press down on the handle’s collar to either adjust the shaft length or remove the shaft and replace it for a different tip. Sets include a handle and multiple reversible shafts.

Screwdriver Bits and Adapters

Square 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.

Square Bits for Impact Drivers

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.

Square Bits for Stainless Steel 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.

Reversible Square Bits

Bits have a different size at each end.

Depth-Limiting Square Bits

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

Triple Square Bits

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

Tamper-Resistant Square Bits

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

Double Square Bits

The tip is shaped like an eight-pointed star.

Square/Phillips Bits

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.

Bit Assortments

Assortments contain bits with multiple drive styles.

Square Bit Sets

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

Secure-Hold Bit Adapters for Ratchet Wrenches

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

Bit Adapters for Ratchet Wrenches

Attach these adapters to square-drive tools.

Bit Adapters for Impact Wrenches

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).

Tight-Clearance Screw Starters

The slim body reaches into tight spots to grip and turn screws that are hard to reach or too small to hold by hand.

Torque Screwdrivers

Torque Screwdriver and Bit Sets

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

Square Drive Torque-Measuring Screwdrivers

Attach a socket to the 1/4" square drive tip. These tools have a dial that shows how torque measurements change as you turn the driver. Use to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners.

Torque-Measuring Screwdrivers
