securing the plywood/vehicle floors

hello i am talking about



i dont know exactly how is named in English so i placed a picture, i am wondering if anyone know any tips for best practices to secure and re-secure them because the repair shops use "self-drilling screws" (pic below)

and the quality is crap, mostly because the "head is small" and is enlarging the hole in the plywood

i was thinking about replacing those with something like this (pic below)


but i wonder if there is any other better option


thx in advance

 

good point i did not think of that, thx

is the floor for the trailer, because loading unloading start to move, so some tightening need to be done

for reference i let here the install guide from some manufacturer
