Klein Tools 70543 – Frequently Asked Questions

1) What sizes come in the Klein Tools 70543 folding hex key set?
The 70543 carries 25 keys across three folding handles: SAE hex in 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32 and 1/4 inch; metric hex in 1.5, 2, 2.5, 3, 4, 5, 6 and 8mm; and TORX in T9, T10, T15, T20, T25, T27, T30 and T40. So inch, metric and star fasteners are all covered without carrying three separate sets.
2) Can I use these hex keys on live electrical work?
No. Klein states the 70543 set is NOT insulated, and the nylon handles are not intended for protection against electrical shock. For energized work you need a tool rated and marked for insulated use. De-energize the circuit before using this set inside a panel or gear.
3) Is this folding hex key set small enough to keep in a pouch or pocket?
Yes. The 70543 set measures 4.56 inches long, 1.57 inches high and 1.07 inches wide and weighs 0.49 lbs for all three handles, so it drops into a shirt pocket or a pouch slot without taking a full tool roll.
4) How far do the blades fold out, and can I use one key without the others getting in the way?
Each blade opens independently up to 270 degrees, so you can set a single key at a right angle for leverage or straight out for reach in a tight box. The case also has openings on the sides that give unimpeded access to the outer keys, which is where most folding sets bind up.
5) How much reach do the keys have for recessed set screws?
Key lengths run 2 to 2.5 inches (5.1 to 6.4 cm) measured from the handle, with a 4.6 inch handle behind them for leverage. That reach handles typical set screws and equipment fasteners, but a deeply counterbored screw beyond about 2 inches will need a long-arm or T-handle key instead.
6) Do the keys go loose over time, and can the tension be adjusted?
Tension is adjustable. Each handle uses a #2 Phillips fastener, so when a blade starts flopping open or drags too hard you set it with a common screwdriver instead of replacing the set.
7) Will these hex keys round out the socket on a stubborn screw?
The hex ends are square-cut and flat rather than ball-end, so the key seats to full depth and makes maximum contact with the socket, which is what resists slipping and stripping. The trade-off: flat ends must go in straight, they will not work at an angle the way a ball-end key does.
8) What are the blades made of and how do they hold up in a damp truck or job box?
Blades are chrome-vanadium steel, heat treated, with a black phosphate finish Klein calls best in class rust prevention. Handles are reinforced nylon in orange, which makes the set easier to spot when it goes down in a panel or a bag.
9) Is it safe to slip a pipe over the handle for more torque on a seized fastener?
No. Klein specifically warns not to extend the handle length on the 70543, and not to use the keys to pry or chisel. Wear approved eye protection when working them. For a frozen fastener, use a proper hex bit socket and breaker bar rather than cheating the handle.
10) What part number do I order for the Klein 25-key folding set?
Order Klein Tools 70543. That is the 3-piece folding set covering all 25 SAE, metric and TORX sizes in one part number.
