For some reason i thought they would be the same size as an 801 atty,but they are the same as a 510,only with 801 threads.No problem for me but thought I would let people know.I will be using them in my Janty Sticks.They are too short but with a regular length 510 Delrin tip installed in place of the origional plug they stick out far enough to be usable. They work real well...should be better than constantly dripping.
