Attempt Initial Fastening

What happens here

The user positions a brass-colored construction screw through a pre-drilled hole in a metal bracket, which is supporting a wooden post. Using a DeWalt impact driver, the user attempts to drive the screw into the wooden post. However, the screw fails to fully engage and breaks off at the head, leaving the threaded portion embedded in the wood and the head separated.
