Klein Tools 603-3 – Frequently Asked Questions

1) Is the Klein Tools 603-3 screwdriver insulated for live electrical work?
No. The Klein 603-3 #1 Phillips screwdriver is not insulated, so it is not rated for contact with energized conductors. Use it on de-energized circuits, panel covers, device screws and general assembly. If you need to work live, you need a 1000V insulated screwdriver instead.
2) How long is the Klein 603-3 Phillips screwdriver overall, and will it reach into a deep panel?
Overall length is 6.75 inches (17.2 cm) with a 3 inch round shank, so roughly half the tool is handle. That is a short-reach driver, good for device boxes, panel covers and bench work, but it will not reach fasteners set deep in an enclosure. For that you want a longer shank in the same tip size.
3) Will a #1 Phillips driver fit the screws on standard electrical devices and cover plates?
A #1 Phillips is the small size, matching #4 and #6 fasteners found on small terminal screws, appliance covers and light-duty assemblies. Most receptacle, switch and cover plate screws take a #2 Phillips, so if you are wiring devices all day, order the #2 tip size rather than this one.
4) Does the Klein 603-3 screwdriver have a magnetic tip for holding screws?
No, the tip is not magnetized. It is a precision-machined #1 Phillips relying on tip fit for grip, so plan on starting screws by hand in overhead or blind work.
5) Is the round shank on the Klein 603-3 a problem if I need to put a wrench on it for stubborn screws?
Yes, that is a real limitation. The 603-3 has a round shank, so there are no wrench flats to grab. For high-torque removal you want a square-shank or bolster-style driver. What this one does give you is a Cushion-Grip handle with internal flanges anchoring the blade against twisting, so the handle itself will take hand torque without the blade spinning loose.
6) What is the handle made of on the Klein 603-3 screwdriver?
Black rubber Cushion-Grip. It is a soft-over-hard grip built for torque and comfort over long sessions, and the black color is Klein's standard. Tip-Ident marking on the end cap lets you pick the right driver out of a pouch without turning it over.
7) How much does the Klein 603-3 screwdriver weigh for a service pouch?
0.15 lbs. Between that and the 6.75 inch overall length, it rides in a pouch or shirt pocket without adding noticeable weight, which is why the short 3 inch shank version gets carried for field service and MRO rounds.
8) Will the chrome finish on this Klein screwdriver hold up in a damp mechanical room?
The shaft is chrome-plated for corrosion resistance and heat-treated for durability, so humidity in a mechanical or boiler room is not an issue for the steel. The rubber handle is not rated for chemical exposure, so wipe it down after contact with solvents.
