HELP, I stripped the head on a bolt of my stem!!(13 posts)

HELP, I stripped the head on a bolt of my stem!!alias 33

I have a brand new trek 2300 and the company put RED loctite on the steer tube clamp bolts!! When I went to loosen the one to adjust the headset it stripped the head and I cannot for the life of me get this bugger off. I'd really like to NOT damage the stem. And by the way where can I get the black rounded head blots the bontrager uses for its stems when/if I get this darn thing off.

So, why don't you take it back to where you bought it and let them sort it out? Could have been the work of a hack mechanic at the LBS.
haha I'm the mechanic who put it together!!alias 33

Bob Villa was pushing a Craftsman product which is used with your drill in reverse. I don't recall the exact name but it is much cheaper than E-Z-Outs. Basically a reverse fluted drill bit, so as it works itself it, it can help turn it the damaged screw out.

Have you seen what they charge for those Craftsman doo-dads? They're like $10 a piece!
Agree w/ Rusty. Take it back to the LBS!RickC5

There's NO WAY you should have to deal with this. The LBS assembled the bike, they should fix it, NOT you.

What if I drilled out the bolt until the remaining rementents of the bolt left in the hole were very thin and then sort of chip/pull them out of there. And is there any certain type of bolt I shoul use as a replacement? Aren't the ones that came in it steel, or are they aluminum?

You could try, but use a reverse drill bit. As you drill, the bit might hook onto the bolt and unscrew it as it goes in. You might need to go to a more specialized store to get the bit. Not something Home Depot or similar would normally carry. These bits are only a few dollars compared to $10 or more for the E-Z Out bits.

They are cheap and you will need them again some day. You can try to drill the bolt out, but you have to be very, very good with a drill. And even then you have to be lucky.

One thing that loosens loctite for sure is heat. When you get the easy out in place hit is with a torch for a few seconds.

...to remove. You can screw around with ez outs, drill jigs et. But its still going to require heat.

Maybe a propane torch lightly to warm it up first.

You have to do better then warm. I think the TG (sofening temp) of most loctite adhesives is around 270F. That means it is hard all the way up to 270F and when you get there it softens quickly. All things considered that is not really that hot, and I would not think it would hurt most stems.

I would have the LBS take care of this; they should have known better than to install the bolts with the red already applied....if they give you any flak, talk to the shop owner and also contact Bontranger....they've obviously got the Boss's son working for the Summer and if he's screwed this one up, he's screwed up a lot more.....Your stem HAS to be servicable !!!!!
Wrong sheet---TDS, not MSDScoonass

Technical Data Sheet should have been pasted in, not Material Safety Data Sheet (Sorry, too anxious to get on the road)

Scroll to bottom of page 1:

For Disassembly
1. Apply localized heat to nut or bolt to approximately 232°C
(450°F). Disassemble while hot.
For Reassembly
1. Remove loose product from nut and bolt.
2. Apply primer to all threads, regardless of metal type.
3. Assemble and tighten as usual.
For Cleanup
1. Residual liquid films and/or fillets outside the joint are readily
soluble in Permatex Brake and Parts Cleaner.
2. Cured product can be removed with a combination of
soaking in Permatex Gasket Remover and mechanical
abrasion such as a wire brush.
