Ashima rotor bolts

Hi,
Guys recently bought sum red ashima light weight rotors bolts, however I decided to change the color, drama is the lbs who fitted them used thread lock and nearly every bolt rounded off trying to get them out,
The new ones ain't fitted yet but my dilemma is are these to soft or was there to much thread lock applied to start off with as these are no more than 4 nn

What are 4nm?
They will be very soft.0 -
Anodised aluminium?
Bad move for rotor bolts IMO.
But threadlock is recommended, so that's not the problem.I don't do smileys.

The Ashima bolts are made of a very soft type of cheese. I believe the same stuff they make MOWA bolts from.
When it comes to rotor bolts, steel is real imho.0 -
Mmm, I've got some of the alu rotor bolts and they are insanely soft, slightly concerned about how I'm gonna get mine out!0

4nm is te Torq setting
Only concern now do I use these new ones or revert to te standard ones that look cack0 -
They're rotor bolts for gods sake. Just use what's sensible, aluminium is not.

Setting on what? Hub or bolt? Not that it matters.0

Whilst you're right CD they are marketed as rotor bolts, and are what Ashima include as standard with their PCB brakes, so one would be lead to believe that they'd be a little more reliable than they actually are. Never had any problems with alu bolts rounding otherwise.
Doesn't help they're T20 heads rather than T25.0 -
I know that, just now that I am old and wise, I prefer not to tempt fate too much. The older you get the longer the pain lingers.I don't do smileys.

ps it's not the rounding that worries me, it's the shearing.I don't do smileys.

Meh, there's 6 bolts, I weigh 11 stone, I'm happy enough.
Did have alu caliper bolts on my XX brakes, they didn't break.0 -
The trouble I've found with all small Torx bits, is that you need some exceptionally high quality tools to prevent rounding off.
Even tools that are generally "OK", can lead to problems.
Anyway, the sensible answer to all this is to forego rotor bolts completely, and use Shimano's centrelock system0 -

I still have no idea what stones are, but I suspect I weigh a few pebbles more than you.I don't do smileys.

Still not as strong as steel in shear."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Well, if each bolt was filled with lock thread ,I'm not surprise that we rounded each off0

Take a look at the shear capacity of aluminium compared to steel. I would never use aluminium bolts on brake rotors.Transition Patrol - viewtopic.php?f=10017&t=130702350

Again, I imagine Ashima must have a degree of confidence in them to supply them OEM with a brake they sell in the US. If you believe their blurb they're a fair bit tougher than 'normal' alu bolts.
A friend of mine used to run aluminium bolts everywhere (stem included) and never had any issues, there is a line for me though!0 -
Updated to sum quality ti bolts,,
As for the ashima bolts found the perfect place and fit like a glove

Don't really get buying Ti bolts except as an absolute finishing thing, such an expensive way to save weight!0

I know but I'm running out of upgrades now apart from wear n tear items looking into carbon crank or newer xtr variant0 -
New XTR is hard to beat, few carbon cranks are lighter (or even comparable) unless you spend far more.0
