TS1 Reed Valve Screws - Size

[Paulnobodyimportant]

My phillips head screws look like they have been loctited fully in and all I'm doing is rounding off the heads. I've a spare cage but no screws. Does anyone know the size so that in can order some. From looking at other forums, hex heads are recommended.

M3 screw threads, too small to tell what pitch they are
