Klein Tools 602-6 – Frequently Asked Questions

1) Is the Klein 602-6 screwdriver insulated for live electrical work?
No. The Klein Tools 602-6 keystone screwdriver is not insulated, so it should not be used on energized conductors or terminals. It is built for electrical work with the power off, panel and component installation, and general maintenance. If you need to work live, you need a 1000V-rated insulated screwdriver instead, not this one.
2) What size slotted screws does the 5/16-inch keystone Klein screwdriver fit?
The tip measures 5/16 inch (7.9 mm) across, so it is sized for larger slotted fasteners: panel cover screws, terminal lugs on bigger breakers, and heavy machine screws. Match the tip width to the full length of the screw slot. Drop a 5/16 tip into a small #6 slotted screw and you will chew up the slot and the surrounding surface.
3) What is the difference between a keystone tip and a cabinet tip screwdriver?
A keystone tip, which is what the Klein 602-6 has, flares out wider than the shank at the blade so it puts more metal behind the twist. That flare is what you want in slotted terminal screws, panel screws, and heavy fasteners. A cabinet tip runs straight down to the same width as the shank so it can drop into a recessed or counterbored hole without binding. If your screw sits at the bottom of a deep pocket, take a cabinet tip; for open slotted work, the keystone is the stronger choice.
4) How long is the Klein 602-6 screwdriver overall, and will it reach into a panel?
Overall it runs 10.938 inches (27.8 cm), with 6 inches (15.2 cm) of that being shank. That gives you real reach down into a loadcenter or a deep enclosure while leaving enough handle outside to get both hands on it. If clearance in the can is tight, a shorter shank is the better pick.
5) Can you put a wrench on the Klein 602-6 to get more torque?
Yes. There is a hex bolster where the shank meets the handle, so you can put an open-end wrench on it and break loose a seized or painted-in screw without wrecking the driver. Combined with the rubber Cushion-Grip handle, it handles fasteners that a plain round-shank driver will slip out of.
6) What is the Klein Tools part number for the 5/16-inch keystone screwdriver with a 6-inch shank?
Order it as Klein Tools 602-6. That designation reads as the 602 keystone Cushion-Grip series with the 6-inch shank length, 5/16-inch tip, round shank.
7) Is the tip on the Klein 602-6 screwdriver magnetic?
No, the tip is not magnetized. It will not hold a screw for you when you are working overhead or starting a fastener one-handed in a panel. If retaining the screw matters on your job, carry a magnetizer or pick a driver sold as magnetic tip.
8) What is the Klein 602-6 screwdriver made of and will it rust in a service truck?
Steel shank, heat treated, with a chrome-plated finish for corrosion resistance, and a black rubber Cushion-Grip handle. The plating is what keeps it from surface rusting in a damp van or job box, though it is still worth wiping it down after wet work.
9) How heavy is the Klein 602-6 screwdriver for a tool pouch?
It weighs 5.6 oz (159 g). Light enough to live in a pouch all day, but with enough handle mass that it does not feel like a light-duty driver when you lean on it.
