Front bumper fixing

2004 Facelifted D2 standard plastic bumper.
There are 3 holes in order to fasten plastic bumper sheet with screws to lower protrusion bar ABY100000.
I found there only one screw type DYP100770L

...and I added the other two. After months I see that those two added screws disappeared.
I'd like to know, in case someone has that bumper, if those would be the right screws that went there.

Thank you in advance!

Regards
