Hex Bits

Quick-Change Hex

Shank

With six contact points, these bits handle more torque than slotted and Phillips bits without slipping and stripping the drive.

Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.

Steel—Best for dry environments, since moisture will cause these bits to rust.

Replacement Socket Bits for Hex Bit Sockets

Switch out worn or damaged bits instead of replacing your entire bit socket. No need for set screws or roll pins to keep these bits in place—they have nylon pellets at their base that compress within the socket for a snug fit. Tap them into hex bit sockets with a hammer. They flex slightly to withstand the high torque and force of impact tools. They can also be used with hand-drive tools.

Continuous-Duty Hex Bit Sockets


	For Hex Drives

These sockets are designed to tolerate continuous use with power tools and impact tools in high-volume production and assembly. They’re hardened to resist wear from repeated use, so they’ll last longer than standard impact sockets. The bit is replaceable—swap out a worn or broken bit with one of the same size.

These sockets require a locking retainer. Use with an impact or power tool that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.

Changeable-Head Torque Wrenches

Change heads to use these tools as an open-end, box, square drive, or hex-key wrench. The handle and head combination you choose may have different maximum torque values. Do not exceed the lower value. The handles come with a calibration certificate, which includes test measurements that confirm accuracy.

You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.

Dual-Drive Hex Bit Sockets


	For Hex Drives

When vertical space is tight or you need an extra twist on your socket, use these dual-drive hex bit sockets. They work with a standard square-drive tool and a box or open-end wrench. Tighten them with your square-drive tool and give them an additional turn with the leverage from your open-end or box wrench. Or just use a box or open-end wrench when you can’t fit your square-drive tool. Pair them with hand-drive tools only.

Fastener-Holding Nutdriver Bits


Quick-Change Hex Shank		External Hex

A mechanism inside the bit holds hex nuts and cap screws in place.

Quick-Change Hex Shank—Quick-change hex shank bits have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.
