    Shimano rotor bolts seem "loose"

    I just got a new wheelset and switched from center lock to 6-bolt hubs... on one wheel I'm using the 6 bolts that originally came from a bike I was using my old Juicy 7s on, on the other wheel I'm using 6 bolts from an older Shimano LX set of brakes (lost the Avid bolts).

    For some reason, the Shimano bolts are very easy to screw into the hub, almost effortless... makes me a little nervous. The Avid bolts are snug feeling like you'd expect.

    As long as I use some blue locktite on all of them should I not worry about it? Or should I replace the loose feeling Shimano bolts?

    BTW, the Shimano bolts have a somewhat triangular shaped head... not round... what's up with that??
    I read that on the internet.

    I'm going to hazard a guess that the Avid bolts have some of the original thread locker left on them and the Shimano bolts have cleaner threads.

    The flat spots on the Shimano bolt heads are a place for Shimano locking plate tabs to bend up against to "lock" the bolts. It seems to be generally agreed upon that the lock plate is not necessary.

    Use blue loctite and a torque wrench and you should be good to go.
