are we talking cosmetic or structural ??
I need to re screw the decking fastener
several choices
longer screws
bigger screws
knock through wood
are these proper decking screws that have been used
how deep are the joists
how old is the decking ??
can you get the screws out they may have just snapped so feel loose
how deep are the joists
do you have a link to the system used iff its a non wood system ??
filler is waste of time
use bigger screws
If no luck, sister to the joist and fix to that
photos of your holy joist would help.
as an aside what have you used to drive them in??
its possible using an impact is the wrong tool as it can strip the grip off the thread
