Klein Tools 600-4 – Frequently Asked Questions

1) What shank lengths does the Klein Tools 600 Series keystone screwdriver come in?
Three shank lengths: 4 inch (600-4), 8 inch (600-8) and 12 inch (600-12). Short shank works in panels and boxes where you cannot back the driver out far; the 8 and 12 inch give you reach down into gear, past deep enclosures and into recessed terminal screws.
2) Can I put a wrench on this screwdriver for extra torque?
Yes. The shank is square rather than round, which lets you close an open-end or adjustable wrench on the flats and add leverage for a seized or painted-over fastener while keeping the tip seated in the slot. Round-shank drivers give you nothing to grip.
3) Which size of the Klein 600 keystone driver should an MRO crew stock for panel and switchgear work?
Most crews carry two. The 4 inch (600-4) for tight device boxes, load center covers and anywhere the cover limits how far you can withdraw the blade, and the 12 inch (600-12) to reach terminal screws set back inside larger enclosures. The 8 inch (600-8) is the middle ground if you'd rather standardize on one. All three share the same keystone tip style and square shank, so bit engagement and wrench-assist behavior are consistent across the set.
4) Does this Klein screwdriver meet a recognized tool standard, and where is it made?
Klein states the 600 Series keystone driver meets or exceeds applicable ASME/ANSI specifications for hand tools, and it's made in the USA. That's the language to quote if a spec or a government purchase calls for domestic manufacture on hand tools.
5) Does the handle come off if I lean on the driver hard?
The blade is anchored into the Cushion-Grip handle with internal flanges, a twist-resistant anchor meant to keep the handle from spinning loose or separating under heavy turning. The shaft itself is heat treated for torque resistance.
6) What material and finish is the Klein 600 keystone screwdriver, and will it corrode in a damp mechanical room?
Steel shank with chrome plating over it, which is there for corrosion resistance as well as a smooth feel in the hand. It'll hold up in normal shop and mechanical room conditions; keep it dry in storage to preserve the plating. It is not a stainless or a coated tool for washdown or marine duty.
