Drivers, Keys, and Bits

Hex Bits

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

Fastener-Holding Nutdriver Bits

A magnet or retaining ring holds the nut in place.

Nutdriver Bits

Turn hex nuts and cap screws.

Bit Assortments

Assortments contain bits with multiple drive styles.

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.

Nutdrivers

These standard nutdrivers have a hollow shaft that provides clearance to remove nuts from long bolts.

Nutdriver Sets

Sets include an assortment of nutdrivers.

Flexible-Shaft Nutdriver Sets

Bend the shaft around obstructions to access nuts in tight spots, such as when securing hose clamps.

Electrical-Insulating Nutdrivers

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 ASTM and IEC standards.

Nonsparking Nutdrivers

Made of aluminum-bronze that is FM approved, these drivers help meet OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

L-Keys

Turn fasteners from either end and reach into tight spots.

L-Key Sets

Sets include an assortment of keys. These simple tools turn fasteners from either end and reach into tight spots.

Ball-End L-Keys

When a standard-tip key can't make good contact with the recess, a ball end allows angled entry to turn screws in hard-to-reach places.

Ball-End L-Key Sets

These assorted keys have a ball end that allows angled entry to make good contact with the screw recess when standard-tip keys can’t. Use to turn screws in hard-to-reach spots.

High-Visibility L-Keys

A bright finish makes these tools stand out, so they're less likely to be misplaced. They turn fasteners from either end and reach into tight spots.

Ball-End High-Visibility L-Key Sets

These assorted keys have a ball end that allows angled entry to turn screws in hard-to-reach areas. The bright finish makes them easy to see and less likely to be misplaced.

L-Keys for Stainless Steel Screws

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

T-Handle Keys

The T-handle provides a good grip for your whole hand and the long shaft reaches into tight spots.

Ball-End Ultra-Grip T-Handle Keys

When a standard-tip key can't make good contact with the recess, a ball end allows angled entry to turn screws in hard-to-reach places. These keys have a textured grip that provides comfort, slip resistance, and maximum torque.

Ultra-Grip T-Handle Keys

The textured grip provides comfort, slip resistance, and maximum torque. These keys have a long shaft for reaching into tight spots to turn fasteners.

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.

Fold-Up Key Sets

Keep a set of keys neatly in your tool box or pocket to turn multiple fastener sizes.
