very nice work. I had to slat 200 special M8 screw. Your fixture gave me an idea for doing them in batches of 7 on my lathe - I replaced the round & hex single screw holder, with a horizontal bar, drilled to accept 7 screws in a row. Then passed them under the slitting saw, as you did, except using all my lathe's cross-slide travel. To adjust slot depth I raised / lowered my Quick Change Tool post holder. Thanks for the inspiration!
