Klein Tools 70553 – Frequently Asked Questions

1) What sizes come in the Klein Tools 70553 folding hex key set?
Thirty-one keys across three folding holders: SAE in 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8 and 1/2 inch; metric in 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10 and 12mm; and TORX in T6, T8, T9, T10, T15, T20, T25, T27, T30 and T40. One kit covers inch, metric and star fasteners, so you are not carrying three separate sets on the truck.
2) Are Klein 70553 hex keys insulated for live electrical work?
No. The 70553 folding hex key set is not insulated, and the reinforced nylon handles are there for grip only, not shock protection. Do not use it on energized conductors. If you need insulated tools, order tools rated and marked for insulated use.
3) How much reach do the blades on the Klein 70553 give me for recessed fasteners?
Blades run about 3-1/2 to 4-1/2 inches long, which is longer than a typical folding set and gets you down into counterbored or recessed sockets. The handle itself is 6.63 inches, and each blade swings independently up to 270 degrees so you can set it straight out for reach or back for leverage.
4) Do the Klein 70553 hex keys have ball ends for working at an angle?
No, the ends are flat, square-cut hex rather than ball end. Square-cut ends seat full depth in the socket for maximum contact and resist rounding out the fastener, but they need close to straight-on access. For approach off-axis you would want a ball-end set instead.
5) Will the Klein 70553 hex key set fit in a tool pouch?
It is a compact three-holder kit measuring 6.6 inches long, 1.36 inches wide and 2.15 inches high overall, weighing 2.84 pounds for the set. Bright orange so it does not disappear in the bottom of a bag. It pouches or bags easily, though at nearly three pounds it is more of a bag tool than a pocket tool.
6) Can I tighten up the keys on the Klein 70553 when they get loose and flop around?
Yes. Each holder uses a #2 Phillips fastener at the pivot, so you adjust the swing tension with a screwdriver you already carry. Snug it up when blades start flopping open, or back it off if a key is dragging.
7) Can I slip a pipe over the handle of a folding hex key set for more torque on a seized set screw?
Not with the Klein 70553. Klein specifically warns against extending the handle length, and doing so overloads the pivot and blade. Use the 270 degree swing to get a full handle of leverage instead, and wear approved eye protection. If a fastener still will not break loose, step up to a socket-driven hex bit rather than cheating the handle.
8) What are the Klein 70553 hex keys made of, and will they rust in a damp job box?
The blades are chrome vanadium steel, heat treated, with a black phosphate finish that resists rust. Black phosphate is a corrosion-resistant coating, not a plating, so keep them dry and wiped down for long service in a damp gang box or truck bed.
9) Can I get to the outside keys without unfolding the whole thing?
Yes. The holders on the 70553 have openings cut in the sides of the case so the outer keys can be pulled straight out without fighting the rest of the stack, which matters when you are working one handed on a ladder.
