Review on Enhancing Structural Integrity: Simpson Structural Screws SD9112R100 Structural Connector by Tyrell Hudson

I have tried them on pressure treated boards and found a 30% failure rate on Simpson construction screws. They fail at the end of the threaded portion of the fastener. I used an 18v cordless drill to install the screws and the Simpson structural screw failed due to 5/16" of the screw remaining outside of the mount. I have used other Simpson structural screws in the past with no problems Structural connectors used but after all the failed screws and drilling new mounting holes to get around the steel sections left in the board I would never use Simpson screws again Luckily I have other higher quality mounting options with Revain where I have no screwing issues. is torn.
