Can anyone tell me how to correctly install APT Thunder Bolts into a concrete drive please? The builders Merchant didn't really have a clue other than "drill a hole and tighten the nut". What stops it swivelling in the hole?

Thunderbolts have a threaded shaft which cuts into the substrate and holds them in.
Make sure that you use a decent drill & the correct size bit - too large and they won't hold, too small and they won't go in
