Perhaps I should admit to never owning a torque wrench myself...  Same here, looking into one now though. TBH though a stems easy enough isn't it? Its gotta be pretty tight or else your gonna get hurt, its always been easy for me to tell when its tight enough using just a regular key.... Hey maybe I'm not always as much of an idiot as it seems! thats what i think, surely doing up a stem doesnt require a £20 tool?! Its a simple job and it doesnt need tools that cost a fair chunk of the cost of the part. Just seems silly for such a simple job. Tim you're missing the point. If you're too stupid to do the stem up properly using both the bolts as it was designed, you CLEARLY do need a £20 tool to do it. Or alternatively, you need to start taking your bike to a bike shop to get it done. Rootes Why are you now questioning my ability to do up a few bolts, i know i made a mistake, everyone does occasionally and im going to have to learn from this one. Im going to give up with trying to get a new one on warranty or anything, so now im going to try and get the stem working again. it doesnt matter if it does work as the stem is worthless anyway. So now, has anyone got any ideas on how to re-thread the stem, or just anyway to FIX it?Lets just forget the whole torque wrench thing and me being special, i made a mistake, end of that. |

drill the holes bigger, re-tap them and buy some larger hardware
simple as
how do i re-tap it? It will be hard to do as i cant reach the other side of the hole easily. Im basing the fact that i need to get to both ends of the hole on tapping BBs. And how much is a tool to tap it? |

And how much is a tool to tap it? Tap tools arent normally too bad cost wise. You dont need to reach the other side of the hole. Just drill the hole out larger, then you put the tap in and twist it like a screw into the hole, it will create the thread, then unscrew it the opposite way very carefully once youve gone far enough. Then you can put in the new bolts, being careful this time i will have a look. And my dad did say this was an option originally. And the bigger bolts will mean it is harder to out beef them. Ill be fine! |

Depends what size the bolt is. A jump from M5 to M6 ain't to bad. But if it's already M6 (5mm allen key socket) it's too big a step to M8.
Helicoils dowork well, but it's the application that's the problem here
Smithy
im interested in this helicoil business. it sounds good but i still have no idea what it is! can you explain? Well i might try what you mentioned about getting longer bolts, but the deity ones are quite long anyway if IIRC |

If the threads in a hole are stripped, you drill the hole a wee bit bigger, tap it to a bigger thread size, then screw in a helicoil. This is a coil with a diamond profile, resulting in a thread on the outside and inside. This leaves you with an internal thread of the original size. Hopefully this leads you to understand why it can't be fitted from the bolt side; you have to drill a hole bigger than that through which the bolt passes!   The drill, tap and helicoil all come in one kit. They are easy to fit when you know how, but this situation would require some careful thinking and planning (not your forte, eh Tim? LOL jokes man) and would require an experienced engineer. They, on the otherhand don't always understand the application fully, so I'd say a dedicated frame repair company (Argos, BETD, George Longstaffs) would be your best bet. But this will probs cost more than a new stem! Smithy |

^^ Helicoil looks a bit complex, and as you said, will cost more than a new stem.
I think my best bet is just to drill out the stem by about 1 mm, then just tap it and run a bigger bolt.
If that doesnt work then i dont know where to go from there.
If it's an M6 thread, you drill it 1mm bigger makes it the ID of an M8, which then requires an 8.5 mm through hole in the clamp and a 14mm counterbore on top of that (numbers off the top of my head from a year or two back). You ain't gonna have enough material by my reckoning Smithy ill try and get some figures of bolt sizes and stuff. Thanks for the help, no one else could manage  |
