Fixing a 47mm thick piece of timber to concrete, how long an expansion bolt will I need?
how long an expansion bolt will I need?
What's the magnitude and direction of the load? I've had a 2" thick piece of timber sat on a concrete floor for years without moving, and it didn't take any bolts at all :)
