[Closed] Loctite 243 ok for stem bolts?

In a word, yes. It's a medium strength thread lock designed for 6-20mm diameters, so should be ideal.

Cheers, didn't want to use it and then find I'm unable to get the bolts undone.

Use it sparingly. Release torque for 243 is fairly high (22NM IIRC) which would be enough to round out some stem bolts.

I'd be looking for something with less breakaway torque. 26Nm is twice the torque setting for my chainring bolts, and 5x my stem bolts

Try some 222 usually purple. Up to 6mm usually fine, as mentioned also for lighter fasteners.

Yeah that 243 will be too much (had a bit of a read up on their site), have now ordered some 222.

Stem bolts are 5nm, chainring bolts are only 4nm due to poly bashring, its more for reassurance, its not like anything's coming loose.

Thanks again.
