Read this for info:-
Thank you for contacting Kreg. Sorry to say, we only have the 3/4" screws in fine thread. With the specs of the screws on how the threads vs the smooth shaft needs to be, with coarse threads on it, there would only be roughly one thread on there. That would not hold at all. Please let me know if there is anything else I may help you with.
Thanks,

Hello Technical Support
I seem to have difficulties buying SPS C075 screws of any qty
Does a coarse 19mm or 3/4" screw exist or is it only available as a SPS
F075?
