Hi, we have screwed on two brackets. A children's swing and a pull-up bar are also attached (up to 200 kg). Holds bombproof 🙌🏼☺️

Hi Tunturi, it's been a while since I fitted the bracket. M10 to M12 screws will certainly fit into the holes. The wood screws supplied are probably about 8-10cm long. I hope this answer helps you. Lg
