Which quality chainring bolts and threadlock?

[techno]

After a near disaster today (one lost and 3 loose chainring bolts, nudity!) I'm looking for quality chainring bolts and which threadlock to use with them?

Ideally I'd like Allen key fitting on both the bolt and nut, I find the slotted type of nut to be annoying.

Thanks.

No direct experience, but I totally agree with you on the dual hex design. I'd have thought something like these Stronglight ones would do the job nicely?

I always use stronglight ones and have found them to be excellent quality and never had them come loose.

Never used threadlock on them. I grease mine to avoid any creaks. I've found they don't come undone as long as I tighten them up to start with

Were the ones you had an issue with alloy? I've had them fail, one went missing and when I took the others out one was loose as it had cracked, which I assume happend to the missing one as well.

No they were steel, and I thought I'd cranked them up to F.T.
But they are old and have been used a lot of times, so maybe the threads are a bit baggy?

Thanks both

I did try some double hex ones from wolf tooth, they were made of alloy, but soft cheese would have held up better

A warning: I used some medium strength threadlock on some chainring bolts (I had the medium strength stuff to hand). When I tried to take them off I discovered that the thread on the bolts is wide - with a large surface area and lots of leverage - and the hex key slot in the middle is small with much less leverage. By the time I got the bolts off they were knackered; and so was I.
I think you'll be ok with weak threadlock. Also, use heat to take them off.

Can't comment on bolts, as I just use whatever came with my GRX cranks, which have a threaded spider. As for thread lock, I think I use the Loctite 248 Medium Strength stick.

Noted!!

Never had a problem with "normal" Middleburn CR bolts, either normal ones or single ring / half height / whatever they're called.

Whatever loctite blue is to hand, think I've got a bottle of 242 and it's been going for yonks.

I should add that these were used cheesium bolts of uncertain provenance, but you probably guessed that.
