Screwdriver Bits

Hex Bits

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

Hex Bits for Impact Drivers

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

Ball-End Hex Bits

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.

Ball-End Screw-Holding Hex Bits

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.

Screw-Holding Hex Bits

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

Hex 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.

Tamper-Resistant Hex Bits

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.

Nutdriver Bits

Fastener-Holding Nutdriver Bits

A magnet or retaining ring holds the nut in place.

Fastener-Holding Nutdriver Bits for Impact Drivers

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

Extra-Grip Fastener-Holding Nutdriver Bits

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.

Nutdriver Bits

Turn hex nuts and cap screws.

Bit Sets

Ball-End Screw-Holding Hex Bit Sets

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.

Hex Bit Sets

Ball-End Hex Bit Sets

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.

Bit Assortments

Assortments contain bits with multiple drive styles.

Bit Assortments for Impact Drivers

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

High-Torque Bit Assortments

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

Precise-Control Bit Assortments

The knurled shank on these bits allows finger tightening. They can also be used with the included screwdriver.

Fastener-Holding Nutdriver Bit Sets

A magnet holds the nut in place.

Nutdriver Bit Sets

These bits are also known as nut setters.

Tamper-Resistant Hex Bit Sets

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.
