Stripped thread on metal back box....aaaggghhh!

[Jim The Fish]

Hi everyone,

Just finnished 2nd fixing a rewire and I have found one of the back boxes for the cooker panel has stripped it's thread on the non adjustable side of the box, my normal course Of action would be to replace the box as it's the non adjustable side but there is a pair of 10 mm s in there and it has been tiled in so the box isn't coming out without a headache. I was thinking of drilling out the old thread and then sticking a nut to the back of the lug with theold thread in to give me something to screw the plate screw into, just wondered if anybody out there had any cunning methdods of getting aroun this situation.

Cheers in advance for any help.

If the thread has gone past the point of being re taped, I usually get a plaster depth 16mm galv back box take one of the oval knock outs drill through either end with a 4mm bit, bend the knackered lug flush with the box, drill two 3mm holes in the back of the box that correspond with the two on the knock out, tap them screw the knock out to the back of the box with shortened 3.5 screws, in line with where the faceplate screw falls normally then drill a third hole in the centre of the knock out thread it, then use a 75mm 3.5 screw as normal. hope that makes slight sense.

nope i got lost after "If the thread has gone " lol

if pennywises's m3.5 rethreading tool doesnt work run an m4 tap through it and use an m4 screw

Make a u out of solid copper wire. Then put it into the stripped hole use a wood screw to tighten.
Clever as a fox eh
