I'm using the E&B/IMS Nanoquartz 200 µm shower screen and the stock LM screw on my Linea Mini, but I also noticed it with the Sproline precision screen and screw. The diffusor screw is screwed in all the way, but I can still rotate the shower screen with my fingers (the screw stays tightened).
I don't figure this matters -- maybe this is happens on all machines and doesn't matter. I only bring it up b/c I use the Espazzola -- so when I wiggle the Espazzola to clean the grouphead I'm really just rotating the shower screen rather than scrubbing it (it still stays clean but this screen is awesome)

Mine don't on either the Cremina nor the E61.
LMWDP #581 .......... May your roasts, grinds, and pulls be the best!

On my GS/3 the screw would bottom out before fully securing in the IMS screen. I ordered one of the 6 hole screws which has a very small o-ring and it secures the screen properly. I do feel I get a few less donut extractions since the water can't just easily flow around the edges.
!! This is exactly what I need. This has been a peeve of mine for friggin' years and could not find any screws other than the low profile sproline one !! That feeling when a long term peeve is about to be conquered, mmmm.
Awesome -- I had previously purchased but not tried this Vidastech screw. I can confirm it holds the IMS screen (200 µm in my case) in place quite well. I don't notice any difference in flow pattern from the screen with the new screw in place, but it is nice that it holds the screen in place better and allows just a tiny bit more headspace.
