Need about 50 unusual Wedge binder seat bolts

[shopcountryside]

Hi,
We have got a bunch of frames with these binder bolts. As you screw them in, they push against the clamp and that holds the seat post in place. We have looked everywhere on the internet and can't find any. We need about 50. Any help would be appreciated. Thanks,
Countryside

If you can't find a supplier you might try to find someone willing to make them for you. You're still asking for 100 of those cylindrical bits with the crescent-shaped cut-out, and that should be an acceptable production run for a small machining company.
