ASA bolt sizes?

[Dusty]

Anyone know what length and thread a standard ASA/Rail bolt is?

Cheers. I would measure one, but I don't have any kicking around.

Also if anyone has a couple they want to exchange for beer tokens, drop me a line.

For reference, the thread is #10-32 UNF. Length varies, but is typically 1/2" or 5/8". Head also varies between cap head or countersunk.

Jim, you're just sooooo technically minded, it kills me.

Screws that screw downwards from the inside of the frame and press against the rail? Grub screws, still #10-32 thread, as are the clamping screws on quite a lot of the expanding-dovetail type rails such as CP and Eclipse dovetail rails.

EDIT: Pictures may come in handy:

Socket Head Cap Screw:

Countersunk Head Cap Screw:

Grub Screw:

I have a few sizes of all of the above, so if you can say which you need I may be able to help
