Klein Tools 627-20 – Frequently Asked Questions

1) What tap sizes does the Klein Tools 627-20 6-in-1 tapping tool cover?
Six machine screw sizes are marked on the Klein 627-20: 6-32, 8-32, 10-32, 10-24, 12-24 and 1/4-20. That covers the common electrical box, device, panel and strut threads, so one tool replaces a handful of loose taps in the pouch.
2) Will the 627-20 chase out the 10-32 ground screw hole in an old steel box that's full of plaster?
That is one of the jobs it is built for. The 627-20 forms new threads, reforms burred threads and cleans plaster out of obstructed holes, and 10-32 is one of its six sizes, so it will clear and recut a plastered-over ground screw hole in a steel box.
3) If I strip a hole out, can I save it with this tool instead of replacing the part?
Yes. Each tap size on the Klein 627-20 rethreads to the next larger size in the sequence, so a stripped 8-32 can be opened to 10-32 and a stripped 10-24 to 12-24. You step up the screw rather than scrap the box or bracket.
4) How do you get to the other tap sizes on a 6-in-1 tapping tool?
Two high-carbon steel taps sit in a reversible holder. You pull and flip the tap to expose the opposite size, so each tap carries two sizes per end and all six sizes are reachable without any loose parts to lose on a ladder.
5) Is it short enough to use inside a panel or a mounted box?
Overall length is 7.625 inches (19.4 cm) with a 1 inch width and 1 inch height, and it weighs 5.6 oz (159 g). That is a one-hand tool that works inside a loaded panel or a box already in the wall, though it gives less leverage than a long T-handle tap wrench on a tight 1/4-20.
6) Can I get replacement taps when they dull or snap?
Yes, the taps are serviceable. Klein lists replacement parts 62632 and 62820 for the 627-20, so a broken tap does not mean buying the whole tool again.
7) Is this a tapping tool or a screwdriver? What does the tool actually do on the job?
It is a hand tapping tool, not a driver, even though it handles like a screwdriver. The 627-20 cuts and repairs machine screw threads in metal: new threads in strut, brackets and enclosures, recut threads in burred holes, and clearing plaster from existing holes. For driving the screws afterward you still need a separate driver.
8) What are the taps made of and will they hold up on steel boxes and strut?
Both taps are high-carbon steel. That is the right material for hand tapping mild steel boxes, channel and sheet brackets, which is where electrical and HVAC work puts it. For hardened or stainless material, a dedicated HSS tap in a proper wrench is the better call.
