Tried a few places without any luck, any recommendations

namrick?

Got some in stock that we use for engine mounting - M10 x 1 x 40mm (12.9 socket head) Give me a call at the unit tomorrow if they are any good for you

Some of your local hydraulics places should keep them.

Depends on your definition of fine. I'd say 1.00 but some say 1.25.

If it's 1.25 there are shed loads on Ebay. For 1.00 there ain't. Namrick would be my #1 choice otherwise.

Though it looks like you might be sorted!!!!
