C.K Rethreading Tool M3.5x.6 is rated 4.8 out of 5 by 26.
Rated 5 out of 5 by from Great Tool This re-threading tool is fantastic, let's you re-thread a backbox when the screw thread is damaged, it's a real life saver if you don't want to change a backbox.

Rated 4 out of 5 by from Useful Tool I unscrewed the sockets in my new kitchen so that I could tile behind them. When I attempted to screw one of the sockets closed, the thread was stripped from the screw. With another socket, the moveable lug fell out and disappeared down a gap in the plasterboard and I replaced this with a spare from another back box. I did not want to try this again, as the double box was crammed with wires. The tool saved me a lot of difficult work and I was able to securely srew the cover back against the tiles. A good, inexpensive addition to my toolbox.

Rated 5 out of 5 by from A must-have tool Bought this while involved in an electrical refurb and really didn't expect to use it. I didn't, as it happens, but since then I have used it innumerable times and it has simply solved a problem of cross-threading or plaster contamination. When faced with back boxes that are stripped, and tiled in too, this tool saves the day...and it costs buttons! I have a "gadget tray" in my main toolbox which holds a number of oddball tools...this is one of them, and I wouldn't be without it. The others include right-angled screwdrivers, a fibreglass contact cleaner for electrical stuff, a 32 piece security bit set and a few other odd bits and pieces...this tool is the most used and the best!

Rated 5 out of 5 by from Easier than replacing boxes. Bought this when I snapped my 3.5mm tap. Really handy for those metal boxes.

Rated 5 out of 5 by from Life saver Perfect for those moments the thread on a metal box fails, just rethread and carry on, no need to replace the whole box anymore. As always fast and friendly service from screwfix staff.

Rated 5 out of 5 by from Stress reliever! Imagine last thing on a Friday, you go to a simple job such as replacing a double socket above a kitchen counter only to discover a thread is gone in the back box... which just so happens to be tiled in! Nightmare! You will be laughing all the way home if you have one of these in your toolbox though!
