Klein Tools 603-6 – Frequently Asked Questions

1) Is the Klein Tools 603-6 screwdriver insulated for live electrical work?
No. The Klein 603-6 #3 Phillips screwdriver is not insulated, so it should not be used on energized conductors or terminals. It's built for electrical assembly work with the power off, panel and junction box build-out, control cabinets and equipment maintenance. If you need to work live, you need a separately rated insulated (1000V) driver instead.
2) How long is the Klein 603-6 overall, and how deep into a panel will it reach?
The shank is 6 inches long with an 11 inch overall length including the Cushion-Grip handle. That gives you 6 inches of blade past the handle, so it reaches into a deep panel or a recessed enclosure terminal without having to choke up on the grip. Round shank, not square, so you cannot put a wrench on it for extra torque.
3) Will a #3 Phillips driver fit the screws in a typical electrical panel or load center?
A #3 Phillips is the large size, suited to heavier fasteners: big lug and terminal screws, switchgear and equipment hardware, larger machine screws. Most device screws on receptacles and switches take a #2, so the 603-6 is the step up from that rather than a replacement for it. Match the tip number to the screw recess, not the screw diameter, or you'll cam out.
4) Does the Klein 603-6 hold screws magnetically?
No, the tip is not magnetized. For overhead work or dropping a screw into a deep box, you'll want to start the fastener by hand or use a magnetic-tip driver or a screw-holding driver. The 603-6's tip is precision machined for fit and torque transfer, which is what keeps it seated once it's engaged.
5) Is this screwdriver made in the USA and does it meet ASME/ANSI spec?
Yes on both. The 603-6 is made in the USA to Klein's standards and meets or exceeds applicable ASME/ANSI screwdriver specifications, which is what institutional and MRO buyers usually need to see on a tool crib purchase order.
6) What keeps the blade from twisting loose in the handle under heavy torque?
Internal flanges inside the Cushion-Grip handle anchor the blade so it resists twisting, and the shaft is specially heat treated. That matters on a #3 tip, because the larger fasteners it drives are the ones that generate enough torque to spin a cheap blade in its handle. The chrome plating on the shank also handles corrosion in damp mechanical rooms.
7) What is the Klein Tools part number and weight for this #3 Phillips driver?
Order it as Klein Tools 603-6. It weighs 5.6 oz (159 g), light enough to carry on the belt all day alongside the rest of a service kit.
8) What does the Tip-Ident marking on the handle do?
Tip-Ident puts the tip type and orientation on the end of the handle, so when a handful of drivers are standing in a pouch or a cart tray you can pick the #3 Phillips without pulling each one out. On a crew that standardizes on Klein, it cuts the wrong-driver grabs that chew up screw heads.
