Hi lads what's the best all round loctite strength for bikes. Just put bigger discs on and used some ss boltsfor the calipers that doesn't have thread lock on. I was going to just order 222 but thought I would check as I will use it wherever it is required.
Cheers
I always use 243
I'd suggest 248- the medium/blue strength pritt stick one. Easier and quicker to use than the liquids, it's a wee bit more expensive but for most people it'll last years anyway
I use 248 stuff in a stick as it doesn't evaporate after two squirt and easy to apply with no drips that eat into things. Downside is takes 24hr to fully set, but for bike stuff it's just to stop bolts rattling out and I only use threadlock on low torque stuff. Typically I've applied in advance anyway but has been no issue applying just before a ride.
Other thing is watch out with how the stuff affects torque. I've snapped bolts using a torque wrench possibly due to threadlock changing the torque spec. The values specified might be based on a specific threadlock or none at all.
As deadkenny says ^^ (torque) "values specified might be based on a specific threadlock or none at all", but as I tend to anti-seize everything else that's a moot point IME
I haven't found that threadlock is necessary in most applications, but I would match the product to the job:
222 has a breakaway of 6Nm and is fine on my handlebar stem that came with threadlocked bolts
248 is 17Nm
243 is 26Nm and seems a bit on the high side for most bike applications
222 for small stuff like rotor bolts and pedal pins. 243 on shock bolts and the like if that's what the frame spec calls for.
Having said that, on some bikes I have ti rotor bolts and I use copaslip for those.
I've not had bolts come loose in any of these applications. More often than not, it's about filling the gaps with something rather than leaving space for water/muck to get in.
I wouldn’t use threadlock of any kind anywhere on a bike apart from bolts etc that come pre threadlocked (presumably for legal liability reasons). I would however use something for anti seize (coppaslip etc) which is a property that many threadlocking compounds have.
Can’t imagine you’d need threadlock on caliper bolts.
Cheers lads. I reserved a 248 stick in Halford however does copper slip gave simular properties as I do use that?
They both reduced to likelihood of seizing.
Correct torque is usually enough to stop things coming undone.
I use copaslip on rotor bolts, caliper bolts and spoke threads to name a few.
Last thing I used threaflock on (222) was race face atlas pedal pins and the axle retaining bolt. The bolt is a known issue but it's only small and I'll want to get it off again one day so 222 is plenty, anything stronger and it wouldn't shift without rounding the head.
Cheers mate. I'll just use the copaslip then. Just pop the calipers back off.
