Hello Vanessa, thank you for your question. Our beds do use a traditional Indonesian style bolt with a rounded end that requires only very simple tools to tighten. These bolts are easily tightened by inserting an hex wrench, thin screw driver, or even a nail into the holes you mentioned and rotating so the bolt tightens. After one crank of the bolt, remove the tool and re-insert it to crank the bolt again. I hope this explains it, but please fell free to message again with any other questions. Thank you!
