Make Sturdy Post Connections
Use galvanized threaded rods to stabilize the rail posts at the bottom of deck stairs.
I recently built a deck and used a pair of 1⁄2-in. galvanized threaded rods to stabilize the rail posts at the bottom of the stairs. This method with nuts and washers on both sides of the stringers creates a rock-solid post connection and uses easy-to-find, inexpensive hardware.

This tip shows a 4x4 notched to accept a 2x. At the point of maximum stress, the 4x4 is only 2" thick.
Most people knowledgeable about installing guard posts recommend against notching, for example, https://www.finehomebuilding.com/project-guides/decks/rock-solid-guard-post-connections.
