Camera attachement bolts

[TheThing]

On my Skywatcher rings, I've got the 'mounts' for piggy-backing a camera, but the bolts are missing. Does anyone know if these are a standard size and where I might purchase some from please?

Cheers!

They are 1/4" UNC bolts. Be careful though you need to make sure they fit in the countersink holes or you'll scratch the OTA. If you find a source, I'd be interested too. I used both of the ones on my tube rings to mount a second dovetail.

Google (1/4" UNC bolts)

There are some suppliers.

I've tried that John, the only ones I can find are either hex nut or allen key, and they aren't suitable for putting in the top of the tube ring, they'll stick out and damage the OTA

Many people fit 1/4 whitworth as they will fit but are not correct.

As loads of gents on here have already said 1/4 UNC.
