thanks for directing me to AHC they do have a excellent stock and I will
use them in future they stock bsf bolts.
unfortunately they don't stock 3/8 bsf grub screws
I going to order from emkay supplies with a few other bits to make the order larger
I didn't think it was a good idea in the end to cut 1 inch long ones down
as they damage easily when holding them
thanks to every one for replying it is very much appreciated
Best Wishes Martin
