Chasing suggestions for a bolt set with a tight-fit head for the hex/Allen key.

The ones that came with my new rotor set were a bit sloppy and soft in the key/bolt head; already stripped a couple.

    Could they be Torx not Allen? All of mine are.

  • I would prefer Allen, as the other main fasteners on the bike are.

    Maybe I need to get with the times?!

    My question was actually were you trying to use an allen key on a torx bolt?

    Not something that I've ever had problems with..???? If they are rounding off they are either really cheap bolts and I'd be worried about the quality of the rotors they came with (are they branded?) over tightening or wrong sized/worn/cheap allen keys.

    Not that stupid :lol: At least not with the bike!

    Anyway, after a bit of reading online, I figured out what I need from a fastener place (stronger grade bolts).

    Thanks.

    Nope, a higher grade refers to tensile strength, no more or less prone to stripping, but they will at least be a known quality and less likely to be made of cheddar cheese.

    Hex rotor bolts are in the minority plus easier to round off. Fit torx heads, it's not like you ever need to adjust them on the trail.
    A dab of thread lock and job done.

    its not the bolts themselves more the quality of the torx 25 tool your using to fit them. I've stripped some bolts recently as the t25 tool I had wasn't tight fitting and made of cheese.

    bought a better set and I'm good to go.
