Hi Di and Kris:
Di, you would hate Giraween NP (Qld). The bolts are so hard to see you almost need a metal detector to find them….

IMO, glue in machine bolts are yet another true-blue, fair dinkum aussie invention. Simple yet functional. As one writter on this site commented, whom else in the world would use a such a thing?
Certainly not the yanks with their big bold p-bolts and brassen bolt hangers.
🙂
