Bits

Slotted Bits

Strong and durable, these multipurpose bits are for use with bit screwdrivers. They are often used with power tools to install sheet metal screws.

Reversible Slotted Bits

Bits have a different size at each end.

Tight-Clearance Slotted Bits

The small-diameter shaft can access screws in narrow recessed holes.

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.

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.

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.

Reversible Phillips/Slotted Bits

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

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.

Clutch Bits

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

Nutdriver Bits

Turn hex nuts and cap screws.

Bit Sets

Bit Assortments

Assortments contain bits with multiple drive styles.

Precise-Control Bit Assortments

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

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.

Nutdriver Bit Sets

These bits are also known as nut setters.

Slotted Bit Sets

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.

Bit Screwdrivers

Secure-Hold Bit Screwdrivers

Lock the bit into the chuck to prevent accidental disengagement.

Tight-Clearance Bit Screwdrivers

Operate these tools like a standard bit driver and access hard-reach fasteners with the offset head. Insert a bit and a magnet holds it in place.

Bit Screwdrivers

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

Tight-Clearance Ratcheting Bit Screwdrivers

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

Fast-Driving Ratcheting Bit Screwdrivers

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.

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.

Reversible-Bit Screwdriver/Nutdrivers

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

Stubby Reversible-Bit Screwdriver/Nutdrivers

When working in tight spaces, these short drivers fit where others can't. Bits have a different tip at each end and snap into the shaft, which is also a nutdriver.

Driver Shafts

Ball-End Driver Shafts

Create your own tool by attaching these shafts to a handle, or use with socket wrenches and power tools. They have a ball end that allows angled entry to make good contact with the recess when a standard-tip shaft can’t.

Ball-End Driver Shaft Sets

These assorted shafts attach to a handle or can be used with socket wrenches and power tools. They have a ball end that allows angled entry to make good contact with the recess when a standard-tip shaft can’t.
