Hello, I am looking for screws for the compression of my jbl 4343 (2420).
It is not the same standard in France.
Can somebody tell me which type of screw it acts? (information to be given to the store which is not near from my home)

ok 1/4 UNC and 1"" length
thanks a lot Ayaboh and fangio
I changed myself the drivers of compressions (the old in aluminium and the new in titane)
the screws were so tight that I have to use a drilling machine to make jump the head of the screws (very carrefully)
but I forgot that the standard of the screws was different (damned )
now I can phone to a shop in paris where it's possible to find screws like this

Well it's an ancient standard but psssst.. don't tell that to the anglo-saxon majority here.
May I ask - why did you choose titan diaphrams as replacement?
my living room is very reverberating
seriously besides I plan to pose an acoustic treatment on the wall of the bottom and the ceiling
I find that the high frequencies are a little too important and hard
one of my friend, with 4345 , has change the aluminium diaphrams for titane diaphrams and the sound is softer (not so straight like aluminiun)
so, as I found originals' jbl diaphrams in titane (and not very expensive !) I wanted to test them
but I forgot the screws (I am a french jbl newbies :-) )

Hi Jacques,
TRy that :

Your English is fine... it i just a bit confusing because these drivers have three sets of screws. The 1/4-20 screws as Edge mentioned for mounting the horns, the non-magnetic #6-32s for the diaphragms and the four square shouldered rather long ~2" (50mm) machine screws that you need to mount the back cap onto the front half of the driver.
Unfortunately I do not know the name for this type of screw or the size of these off the top of my head. They are a standard machine screw, but are not a particularly common style. I have always ordered them directly from JBL. This is not a realistic option for you. Maybe Guido or another European member has a source for them.
