You know those nuts that thread onto the chainring bolts? Why the heck are they the only nut in the universe with that stupid seperated flathead pattern that requires a stupid seperated flathead tool? Why can't they just be a friggin flathead, that accepts a flathead screwdriver? That stupid freakin' design doesn't even freaking hold!!! You have to torque the snot out of that bolt and the freaking nut holder tool stands up to approximately 1 foot pound of gosh darn torque! Holy carp! I'm friggin furious!

get over it... and learn do the job right (torque bolt with allen wrench while using the tool to hold nut on the other side). are you proposing that someone design a new type of chainring/crank interface, a la threadless forks/headsets (something we all just couldn't live without before)?

Pay no attention to this guy. You just keep mangling your bike parts Alex and be sure to tip your mechanic when he fixes your mess. Got to keep the mechanics bizzy, otherwise they'll be making time with all the chicks and not even leave so much as a leftover for all the flaccid little men on this board. Remember, chicks dig dirt under the fingernails.

I know what you mean. Seems to me that a better design would be that an allen wrench or bolt could fit in the back of the bolt so that you would have two allen wrenches torquing on the chain ring bolt. Just a thought.
Bottoming out?gust-of-sun

One reason those tools are so flimsy is 'cause they only need to add friction on the back of the nut. once the bolt is a little snug, i've found the friction enough to torque the allen wrench against. I've even broken a chainring bolt by tightening to much. As my German friend says, First is very tight, then is very loose.
Make sure you're not bottoming the screw in the nut. regular chainring bolts that look like they'll work for singlespeed are the biggest culprit. See if putting a washer in each stack solves the problem.

I found this loose bolt in my search for a BB area creaking noise on my Chorus 10spd bike. First place I checked was the crank bolt, then the chainring bolts. I checked them one at a time, just with the allen wrench, not the the nut bracer, and all held firm except one which just rotated right and kept on going. I knew from experience (I've stripped the heads off of more than one of these things) not to keep trying until I could brace the nut. Well, I don't have that tool so I tried using my finger-tip, a big flathead screwdriver and a butterknife. Non worked.

Anyway, the bolt and the nut are intact, I just need to stop by and purchase that little tool. My beef is basically with the pattern on that nut - why does it have to be unique? Even if you don't need much torque, does the nut have to be designed around a pattern that is incapable of supplying torque? It just seemed like another area of intentional incompatability. As the fellow above said, a shallow hex pattern could serve the same purpose without the unique tool.

Thanks tho, I'm going to stop by and buy the bugger this afternoon. If you're there I'll come say hello.
