Loctite on chainring bolts?


A week or so ago I changed the chainring on my fixed gear from one side of the spider arms to the other side, trying to get a straighter chainline.

Today I was doing a checkup on things and noticed one of the (5) bolts was missing, and one was pretty loose.

I had some spares so I replaced and tightened everything down again.
I don't have one of those tweezer looking chainring bolt tools, I just used a big flathead screwdriver.

Did I just not get the bolts tightened down properly when I moved my chainring (since I didn't use the right tool)?

Or should I be using loctite or something on the bolts?

And one more, is there a chance I messed up my chainring riding around missing a bolt?
Other than if it were completely taco'd I imagine it'll be fine now that its cinched back down tight, right?

I've never had a chainring bolt loosen and I've never used loctite, just grease. You don't need one of those chainring bolt tools, although sometimes they can be handy (I have one but rarely need it, just my fingers most of the time). Was the chainring running true on install? Is the spider mounting surface perhaps off a bit? Otherwise I'd think you just didn't tighten it in the first place. If the chainring got a bit tweaked just bend it back to true.

No need for loctite, at least not most of the time. Your chainring should be fine, just install a new bolt, and make sure everything is nice and tight. It's worth checking again after a few weeks, just to make sure nothing came loose. If it's good then, you can safely ignore it.

+1 I use grease as well, not loctite. I also use that cheesy chainring tool. I find it helpful, but I am usually dealing with a bolt that has not been taken apart in 25 years. Some are not that cooperative..

Using blue loctite won't hurt, and it will prevent the bolt from backing out.
