the pic was to show...the hold downs are not strong/mis use....they will pull out fold over...if that makes sense .....so...no sheet metal screws...they will just pull out...if you need some solid tie downs....then follow the suggestions...

 

Ok thanks guys that's what I was looking for. I was thinking of sheet metal screws because I saw on other threads some people used them but they never said if they held. So I will not be using sheet metal screws. Will prob just put some on the floor.
