• Thanks for your comprehensive response.

    I've measured the current bolts I've used and they are 7mm from the bottom on the integrated washer to the top of the nut. This cases the dust caps to sit nearly 2mm too far out and they are not flush like they're supposed to be. This is why I thought there was a specific Campag bolt.

    Now, what is the combined measurement of the Campag nut and washer that you have?

    And would the Royce bolts fit flush in a record pista crank?

    Thank you

  • You're welcome.

    I've measured the current bolts...

    Me too and the shallowest (cheapo, unbranded) are also 7mm. I don't have any Campag bolts.

    And would the Royce bolts fit flush...

    Assuming your measurements are correct (you torqued then up adequately?), no.

    FYI the part number for Pista bolts is FC-PI004 and last listed in the catalogues in 2009.

    Also FYI, Campoldy note that the dustcaps are "as fitted to 2nd gen. Super Record through to current Pista", which widens your search (no doubt the part number has changed).

    I'd contact Campoldy, Condor, Mercian and Sidcup Cycles: they may have some gathering dust, which aren't listed online.

    And if I summon @gfk_velo he can no doubt put us both straight on the subject (or contact him at Velotech Cycling).

    Alternatively the bolts are M8, so you could shop around for a shallow-head version and stump-up for the dustcaps.
