777(all permissions) - 444(read permissions) = 333, the umask for only readable permissions is: 333

Have a look here: Setting default permissions
umask (as its name says) is a mask and you have to remember that what you set is to be subtracted from 777 to get the require file creation permissions.

umask 000 - will mean created files have perms 777
umask 022 - will mean create files will have pwems 755
