Epee screws:
- LP screws are the best because they are maximum fit for german/french tips with cutting thread.
- German screws are 2nd best because they have better standardization in diameter to almost maximum fit but with regular thread.
- French screws are the worse because they have greater variance in screw diameter with regular thread.
In general, I use german tips with german screws as I buy most of my blades wired. If I need to readjust the springs, I still replace the german screws back. If, on the other hand, I lose a screw during fencing, I then use LP screw to replace the screw. After 3 occasions on losing a screw, I change the tip and start with german tip/screws.

I generally recommend using matching brands of screw and tip (but I don't lose sleep over doing otherwise). It makes no sense to picture your typical screw vendor testing the screws on all the competitiors' tips, but I have this (excessively idealistic?) image of a screw vendor putting his own screws into his own tips and learning if they're good enough for that use. I decline to comment on French vs. German screws, but I wholeheartedly concur about Leon Paul screws! Leon Paul at Summer Nationals reported they were doing a brisk business in screws, presumably from all the people who know the secret! I defer to the rest of the community to provide the requested comment on Estoc screws. In general, I use german tips with german screws as I buy most of my blades wired. If I need to readjust the springs, I still replace the german screws back. If, on the other hand, I lose a screw during fencing, I then use LP screw to replace the screw. After 3 occasions on losing a screw, I change the tip and start with german tip/screws. Suggestion: When you have a screw problem (like losing one), use a fine-tipped marker on the shaft of the tip just behind the front, or some other distinguishing marking so you can tell the difference between one side of the tip and the other, to see if your next screw problem is on the same side or the opposite side. I'd hate to have a policy of replacing a tip upon losing three screws if two of the screw losses turn out to be the same person on the same day putting two different screws into two different holes on opposite sides with the same insufficient torque. On the other hand, you have to use your information about whether the problems are one hole or both holes with care. Let's say you know you're having problems on both sides. You have to decide whether it's more likely that both screws suffered from the same inadequate tightning, or whether both screw holes are showing that they aren't in good shape. There is one screw which will stay in place even better than a Leon Paul, but it must be used with discretion and great care. Use a small amount of some adhesive. Make sure zero adhesive ends up in the wrong place. I've done this in mid-tournament when I had faster access to CA than to a different brand of screw (or to a new tip and the time needed to adjust the spring).

Don't know, Let's get some different screws, a metric micrometer and some thread gauges and find out.

When he asks about Estoc and Schermasport screws, is he referring to their designs for tip screws, or their screwless tips?

Don't know, Let's get some different screws, a metric micrometer and some thread gauges and find out. Forget the thread gauge. All these screws are more or less interchangeable precisely because they are all the same nominal size and pitch. So, the thread gauge will only tell you the same thing for all.

The French and German are Class 2 fit, while the Leon Paul is a Class 1 fit. They are the same size though. The difference between Class 1 and 2 is 1 threads are made pointed to give more contact surface area.
The Schermasport looks more like a large French foil screw. It is not compatible.
I haven't worked with the Estoc.
