Threadlock versus anti-seize, when to use?
So which parts and bolts on a bike will benefit from threadlock and which will benefit from anti-seize compound?
I see threadlock used on all disc brake bolts: the ones used to mount the adapter to the frame, those used to attach the caliper to the adapter and those used to attach the rotor to the hub.
What about other bolts and parts? Rack mounting bolts, brake/shifter lever bolts, stem/handlebar bolts, etc.?
Thanks.

Thanks!
There is a link in one of those posts to Park web page with some good info. So I think I'll use some blue Loctite on my rack bolts.

If you have a fastener which you fear might loosen, then threadlock (blue locktite) can be used. I'm not sure what that might be. If you have any SS screws being threaded into SS nuts, then anti-seize would be called for. Or, if you have some threaded fixtures which get real hot. Otherwise just use some grease to help avoid corrosion.

I had those in mind when posting the question. Also, I may use blue Loctite on handlebar and stem bolts then. So it looks like anti-seize compound isn't all that necessary on a bike. Yes, I use grease on all threaded parts.What about pedals? Does it make sense to use threadlocker?
Thanks!

I don't think it's important to use a thread lock on pedal bolts. Grease them to forestall corrosion, but they don't loosen on their own, in my experience. I think the natural effect would be for them to tighten in use rather than loosen.

Dont use threadlock on pedals because the pedaling motion tends to tighten them, but use anti-seize if you ever intend to remove the pedals. I also use anti-seize on seatposts and seatpost bolts.

+1 Threadlock on pedals is a bad idea. I use anti sieze on bottom bracket threads, on freewheel hub threads and on bottle cage bolt threads. Everything else gets grease.

What I do:
* Anti-seize: BB, chainring bolts, pedals.
* Blue Loctite: Everything else.
Although I think wrk101 may be right about bottle cage bolts.
I can't remember ever having one loosen up on its own, but I have nearly destroyed a couple trying to loosen them.

Probably one of the most incorrect posts i've ever seen in all of bikeforums. You must go through a lot of loctite. Even on interfaces that require grease instead.

Loctite on fasteners that are *not* supposed to move.

Loctite on jockey wheel bolts. That's one of those situations where you may not be able to ride home, especially if there is grass in the ditch, though you can always go SS.
I use anti-seize on stem bolts, etc. Never saw one loosen. Also on nipples. Never had one loosen. Important on bottle cage bolts, pedals, etc.

Never use Loctite on anything that is used to retain a plastic part. As Loctite cures, it gives off ammonia gas, which can cause some plastics (polycarbonate, especially) to become quite brittle. They will stress-crack within days.
