  <p>Like I mentioned in my comment, it appears LEGO is comfortable using a single stud to hold this piece when attached by its anti-studs.

  <p>Using the modified brick you’ve suggested will definitely provide a stronger connection in addition to preventing rotation. I haven’t been able to find an official stance from LEGO on whether they recommend connecting to multiple anti-studs with the same piece.</p>

Answers.Text: That shield piece has a lip around the edge, which stops tile from rotating. Single stud, probably, was efficient enough in such case.

  (Asked by: username_0 on 2021-06-06)
  
  Do the [Pentagonal Power Shields](https://www.bricklink.com/v2/catalog/catalogitem.page?P=22385pb095&name=Tile,%20Modified%202%20x%203%20Pentagonal%20with%20Nexo%20Power%20Shield%20Pattern%20-%20Toad&category=%5BTile,%20Modified,%20Decorated%5D#T=P&C=19) have 2 anti-studs on the back. Would they attach more firmly to a [LegoBrick, Modified 1 x 1 x 1 2/3 with Studs on 1 Side](https://www.bricklink.com/v2/catalog/catalogitem.page?P=32952&name=Brick,%20Modified%201%20x%201%20x%201%202/3%20with%20Studs%20on%201%20Side&category=%5BBrick,%20Modified%5D#T=P) then a basic headlight brick?

  Yes, they have two anti-studs. You can see both through the [trans-clear version](https://www.bricklink.com/v2/catalog/catalogitem.page?P=22385&name=Tile,%20Modified%202%20x%203%20Pentagonal&category=%5BTile,%20Modified%5D#T=S&C=12&O=%7B%22color%22:12,%22iconly%22:0%7D) of this part on the back of [76193 The Guardians’ Ship](https://www.bricklink.com/v2/catalog/catalogitem.page?S=76193-1&name=The%20Guardians%E2%80%99%20Ship&category=%5BSuper%20Heroes%5D#T=S&O=%7B%22iconly%22:0%7D).

  The basic headlight brick or Ehrling brick <https://www.bricklink.com/v2/catalog/catalogitem.page?P=4070> has its side stud recessed half a plate, so there is a bottom lip that's in the way to attach any plate or tile in the central tubes... Any other element with 1x1 or 1x2 studs fits rather tight in the tubes, tighter than other anti-studs but it's a perfectly legal building technique as far as I know...
