Removing a cross-threaded screw :(

[Pumpkin the robot]

Um I would nt like to be going down hill at 40 mph ....knowing I have just re-taped the stem where my hands hang onto .... Buy a new one Play safe !

Using a helicoil kit it will actually be a better thread than the original, especially if it is in aluminium.

You're welcome to have the borked stem if it's of any use to you.

Its ok, I already have too many spare parts in the garage!

I wasn't aware that was feasible

I think that as well, but apparently I am wrong or so I am told by SWMBO.

they just don't understand he concept of a garage... Dads 'SWMBO' (aka Mum) is always moaning at him for a; filling the garage full of crap. b; knocking the garage down and getting a double garage built so he could fill it full of crap and leave space for the car. And c; filling the car half full of crap too. If mother had her way, the garage would be empty, free of all dust, and the car wouldn't be allowed in in case it dripped oil on the floor

true that with the postal service thingy!
how much does a stem weigh i have not removed one for ages?! if it is very heavy it's not worth me paying for postage you see
Cheers Ed

[QUOTE 2855157, member: 45"]Is this the one you screwed in from the wrong side? If so you screwed it into the only side that is threaded so you'll have a length of undamaged bolt in the other other side trying to get through the threaded part. Good luck.[/quote]

Sadly not, I think it was threaded the whole way through. I tried putting it back in the correct side and it turned and turned.

 

[Andrew_Culture]

Do you have a set of taps and dies? Running one through could rescue it.

Sadly not, although I am impressed that I know what you're on about.

true but it depends on how much metal there is aount the hole. to reduc weight, many stems have lugs for the bolts so not much metal - helicoli will need drilling the hole to a larger size.

an alternative would be to fit a longerbolt with a nut but it would look shite and sooner or later your will catch your knee or tights on the bolt.

 

[Pumpkin the robot]

It depends if the outside of the threaded side of the hole is flat, otherwise it would need to be counterbored flat for the nut to sit on it. Most stem bolts are M5, the head for an M5 caphead is 8mm diameter. A helicoil would need to be drilled out at 5.4mm from memory and then tapped, so another .4mm per side, there will be plenty of material in there for helicoiling, but it is more expensive than drilling a hole through the thread and filing the back flat of required and using a screw and nut as you suggested.
Just offered my services to the OP as it would take me no time to sort it out properly.
