Anyone using loctite on threadless stems and headsets?

I was thinking about using loctite on threadless stems and headsets to prevent theft. My son is away at college, the college is not located in the best area of town, and just had his stem and headset stolen from his bike.
My thoughts were to use red loctite to prevent theft. To remove the stem and headset for maintenance reasons, heat would probably have to be applied. My thinking is replace the old stem and headset with a new inexpensive stem and headset.
Does anyone have thoughts about using red loctite?
Thanks,
Gary

To steal a headset, assuming it was seated well, the thief had to bang it out with section of pipe or something at least, if not an actual headset removing deal. If red loctite was used and someone went to steal it in the same fashion, they just might bang the hell out of it and hurt the headtube. So I dunno, maybe something like just have an inexpensive stem and headset and get like a torx bolt to replace the allen bolt on the top cap? Or some online places sell allen bolts that have a thing in the middle that makes it impossible to use a regular allen bolt, you have to have a special wrench they also sell.

Like these sort of things:

I've found exact matches before, the pin-head allen bolt that's the same as one used w/ a top cap at some online hardware store, but I can't find the place.

Specialty fasteners with non-standard heads or glue something in the socket like a nut for which you have the proper solvent with which to dissolve the glue when it comes time to service.

There is a brand called pinhead which sells bike specific stuff, don't get the hub skewers as those have been proven deflatable using a pair of locking plies... they do sell a headset screw though

I used to super glue old ball bearings into the heads. Works great at filling the hole so an allen wrench can't get into it. When you need to work on it, a little acetone nail polish remover works to dissolve the super glue. Glue them into the stem, headset, and seatpost binder.

****ing idiotic if you ask me.

Pitlock makes a security skewer that locks down the topcap to prevent theft.

They're not stealing the headset, that's ********. They're looking to steal the entire handlebar with shifters/brake levers attached.This has been done before.

TimJ, electrik, and rcummings1 thanks for your help[ful answers.

I am not sure what problems cab horn and stevetone have but the responses were pretty useless.
Normally, I wouldn't say anything about their posts but looking at many posts on this forum I have not yet run accross a post by cab horn that was very helpful. cab horn does post a lot.

We operate our shop in one of the highest bike theft areas in north america. We know what we're talking about. Theives don't steal stems or headsets. They're after the shifters if they are looking to steal them - they will take the entire bar and this ever only happens if you have expensive flat bar shifters or STI's on them (and since you don't even tell us WHAT bike it is, let's just randomly guess every single bike ever made). Red loctiting, gluing ball bearings in, filling it with glues are great if you never want to service your bike in a timely fashion. Especially when there are products out there that do that exact function which I will mention for the second time.
If you need to outfit a bike with all these anti-theft measures it's probably IS too expensive for a campus lockup. Which is exactly what post #8 said.

What I used to do was load the allen key holes with 3M 5200. RTV might also work. You need to use a dental pick to remove it.

Don't use loctite. When the bolt is removed for servicing, there is a good chance of taking aluminum threads with it, or shearing the bolt head off.

Listen to the posters talking about using a specialty locking fastener... they're not cheap but do work and are convenient. I have never seen people steal actual headsets though, unless we're talking about a bike that has been locked up for months and picked clean by the urban vultures - but by then one guy has the fork with the lower race and a different guy has the rest of the headset.

On a lighter note, I also recommend a large sack with which to encase your ride, preferably made of kevlar or aramid fibres for locking in high-crime areas.... patent pending! Otherwise just remove the nice looking parts if you're parking in high-theft areas(campuses) there is no way to protect it for extended periods.. better to just offer less to the theif.

For years, I've being putting drops of mercury in the head of all my bolts. This make the thief think it's a ball bearing and they know they'ew foiled!
For those worried about health hazards, no sweat. It hasn't affected me a bit.

This is good news for those old-school thieves who carry picks.
