When my workshop was broken into this spring, the thieving theivers decided to take (among other things) a mint tin full of rotor bolts.  Why?  I can’t say- but it’s been awfully hard to put rotors on wheels without any.  Looking to replace them on a well-known auction site, I stumbled across Ashima’s blue steel rotor bolts.  Click through for more details…

Though I know that many people have successfully run aluminum rotor bolts, steel really does seem a whole lot more sensible.  At $10.35 for two wheels’ worth (shipped from Taiwan), the Ashimas are priced about the same as other steel bolts.  But they’re bluer.




  1. Good story, tell it again. I was hoping maybe you found your stolen rotor bolts on E-bay, that would have made for some quality entertainment.

  2. Wait. You had a hard time finding steel M5 x 10 button head bolts? Did you look all of three places, and were those places only in your house? Seriously? It appears that on a scale of 1 – 10, your effort to find such bolts was about 0.1.

    Was the real problem a lack of desire to engage in movement? To have to get up from your chair? Why is this even a story?

  3. Fortunately, you can apply the same torque to a socket button head as you can to a torx button head. One may not be as pretty as the other, but they both work just as well.

  4. @ Robin…

    do you mean hex or allen Socket button head??? cause Socket button head can refer to hex/allen, torx, etc…

    Socket button head is kind of a generic term now-at-days…. also, while it is true that you can apply the same torque.. you’re far less likely to slip and strip the head of a torx than an allen.

    Plus.. the hardware store doesn’t carry all those cool colors!

    ANyways… more of the story… CHILL OUT!

  5. Robin, If you’re going to be a know-it-all at least try to be right.

    All else being equal, you absolutely can transmit more torque through a torx interface than a standard allen/hex interface.

    Allen button head will strip faster due to deformation of the screw recess or the tool.

  6. Thanks for the tip. I both some from these guys after reading your post. Just turned up today.
    Looks like I got the last of the Blue ones 🙂
