AshmanOnline Ground Screw 4 Pack – No-Dig U-Model Post Stake, 27in, Fits 4x4 Mailbox Posts

Overview

The AshmanOnline Ground Screw is a practical no-dig solution designed to anchor round posts and mailbox bases without traditional holes or concrete. At 27 inches long, the threaded steel anchor reaches depth for stability while remaining removable when needed. The kit comes as a 4 pack, giving you a consistent and clean install for multiple posts or a paired setup for a single project.

What makes it reliable

Made from galvanized steel, the ground screws resist rust and weather, ensuring durability outdoors. This U-model screw-in post stake accepts a standard 4x4 wood post (post not included). Hardware is included so you can start installation right away, with a tightening rod and six lag bolts arranged for balanced mounting.

• 27 inch length designed for standard 4x4 posts
• Galvanized finish for rust resistance
• Includes tightening rod and six lag bolts
• Two bolts on one side and three on the other for balanced load

Installation and removal

Drive the screw into the ground by twisting until it is deep enough to secure your post. When the season ends, unscrew the anchor and remove it without leaving holes or concrete behind. The anchor is easy to reuse for future projects.

Use cases and compatibility

The system works well for mailbox posts, flag poles, or garden structures. It accommodates a standard 4x4 wood post (not included) and arrives in a 4 pack to support multiple posts with a uniform footprint.

• Works with standard 3.5 x 3.5 inch square posts (4x4)

Practical benefits

Actual results vary by project, but this design can speed installation, minimize lawn disruption, and simplify seasonal changes. It provides a flexible alternative to traditional footings for temporary or semi permanent outdoor setups.
