Secure Horizontal Beam with Pilot Screws

What happens here

Place the horizontal wooden beam onto the pre-installed metal bracket (if applicable) or directly against the marked position on the vertical post. Using a drill/driver, insert one or two initial screws through the horizontal beam into the vertical post. These screws provide temporary stability and hold the beam in place while further reinforcement is applied. The video shows the first screw being driven near the bottom edge of the horizontal beam into the vertical post.

Goal: Attach the horizontal wooden beam to the vertical post, typically resting it on a pre-installed metal bracket, and secure it temporarily with initial screws using a drill/driver.
