Holdsworth Binder Bolt

[Melon]

Hello retrobikers,

Does anyone know what type of binder bolt would sit the bike pictured, would be a sunk allen key bolt (I presume), is there a common size?

And can anyone point me to the right place? Modern is fine

I'm working from memory, always good for a laugh but I think they are M5 x 25mm Socket head bolts

There's loads on Ebay, but I'd just wait for someone to confirm the size.

Lovely, the help is much appreciated!

Looks like 6mm to me, the same thread as most old brake centre bolts?

Tried an M5 and it was a tiny bit small, so maybe an M6 might be the one.

:facepalm: Just checked the one on my Rotrax, its M6 x 20mm
