    I'm using two small locknuts on a miniature ballscrew (R1202) and I cannot seem to find a suitable c-hook wrench or some other tool which would allow to tighten two M10 x 0.75 locknuts to hold the ballscrew end in a bearing.

    Has anyone seen anything like this somewhere? or do I need to make my own?

    Regards,

    Hi DSC
    can i assume you are looking for a thin (plate) spanner?
    If so try a search for Park Tools (cycling gear) thin open ended spanners are required for adjusting the wheel bearings on bikes, can't remember off hand what size mine are but think there 14mm.
    Regards

    Hi Mike,

    I remember seeing a set of those on my dads bike when I was a kid, didn't know what they were back then, but indeed it looks like they might work. I'll try and get a single small one to try it out.

    Cheers,
    dsc.

    If it is thin spanners, then in the bike trade they're classed as cone spanners.

    However, going by the original post, I would of guessed it's a hook spanner you're after?

    This spanner would do as well, there's not much tightening to do, a hook spanner would be better, but due to the way the locknut is recessed in the housing, the ideal thing would be a locknut socket, but those are stupidly expensive.
