Klein Tools 600-6 – Frequently Asked Questions

1) What does the square shank on the Klein 600-6 actually do for me?
The 6-inch shank is square rather than round, which lets you put an open-end or adjustable wrench on it and turn the driver like a bolt. That's how you break loose seized terminal screws or set large lug screws without twisting the handle out of your hand. A round-shank driver gives you only hand torque.
2) Will a 5/16-inch keystone tip fit the lug screws in my panel?
The tip measures 5/16 inch (7.9 mm) across in a keystone profile, meaning the blade flares out to full width at the tip rather than tapering like a cabinet tip. That width suits the slotted lug and ground-bar screws found in load centers and larger terminal blocks. For narrow slots recessed in a counterbore, a cabinet-tip driver of the same nominal width is the better choice because the flare on a keystone tip can bind on the shoulder.
3) How long is the Klein 600-6 overall, and will it reach into a deep panel?
Overall length is 10.938 inches (27.8 cm), of which 6 inches is shank. That gives you enough reach to get past wire bundles to gutter-side terminations while keeping the handle clear of the deadfront. Weight is 0.4 lbs, so it's not a bulky tool to carry on a belt.
4) What is the Klein Tools part number for the 5/16-inch keystone screwdriver with a 6-inch square shank?
Order it as Klein Tools 600-6. It is a single configuration, 5/16-inch keystone tip on a 6-inch square shank with a black rubber cushion handle, so there is no finish or size option to specify.
5) Is the tip on this Klein keystone screwdriver magnetized?
No, the 600-6 has a non-magnetic tip. Screws won't stick to it, so for starting a cover screw overhead you'll want to hold the fastener by hand or use a magnetizer. The upside is no attraction to loose metal filings in a panel.
6) Can I use a hammer or pliers on this screwdriver to free a stuck fastener?
Use a wrench on the square shank, not a hammer. The square shank is the intended way to add torque, and the handle uses internal flanges anchoring the blade so it resists twisting off under load. Striking the handle is not a use the tool is built for, and prying with it can bend the heat-treated shaft.
7) Are the handle dimensions on the Klein 600-6 big enough for a gloved hand?
The handle measures 2.367 inches by 1.125 inches, a full-size cushion grip in heavy-duty black rubber rather than a slim precision handle. That's enough body to get a gloved hand around it and apply real torque without the grip rolling.
