CK Re-threading Tool M3.5x0.6

This tool has saved a lot of time when dealing with damaged or tight M3.5 threads, especially in electrical back boxes and accessories. It cleans and restores threads easily, allowing screws to go in smoothly again without forcing or replacing the box. The build quality is excellent, and it feels solid and precise. The handle is comfortable and gives good control when re-threading. It’s a simple tool, but incredibly useful and worth having in the kit. Definitely a lifesaver for electrical maintenance work.

Great little tool! I already used it and it works great! I even drilled a 2.5mm pilot hole in plastic and used it to cut a new thread and it worked perfectly!

But too small for hand but good quality and easy to use does the job

This CK re-threading tool (M3.5 x 0.6) is a very handy thing to have in your tool bag. It’s perfect for cleaning out damaged or paint-filled threads in switch and socket back boxes, making fitting screws much easier. Simple to use, well made, and does exactly what it’s designed to do. One of those small tools that proves its worth very quickly.

Just as described, worked a treat. I actually used it to cut an entirely new thread (in quite soft metal) after failing to extract a screw that seemed harder steel than the material it was in, and so ultimately drilled it out for a slightly larger hole. Not really meant for that though, but no doubt it can realign somewhat existing threads nicely if it can cut anew.

Good tool easy to use

Worket perfectly to rethread some old sockets. Not the best quality plastic handle, but the business end is very well ground. Time will tell how well she lasts, but done a round of sockets and all good so far.

Had to re-tap the lugs in the patress box behind a light switch, this should have been ideal for the job but just didn’t work for me, maybe the lugs were too far gone. The tool itself is well made and easy to use so can’t complain on that score.

Muy pequeño
