Recessed holders are just fine, even if you fully tighten the screws. I purchased many cards already in them during the late 80s and early 90s. Some were screwed so tight that there were small spider cracks near the holes.
Who knows how long the dealers that I purchased the cards from had them in there. I kept the cards untouched and in them for more than a quarter of a century. In 2019, I had the cards all graded. They all received numerical grades.
