I've tried using them on boards Simpson- Structural Bolts They will eventually fail I used an 18v cordless drill to install the bolts and the Simpson structural bolt failed due to 5/16" bolts remaining outside the bracket. I've had none in the past Problems have used other Simpson structural connectors but after all the failed bolts and drilling new mounting holes to get around the steel remaining in the board I will never use Simpson bolts again Luckily I have other higher quality mounting options with Revain that I am using I have no problems with splitting screws.
