CDFYJHFDQ 22-inch Fence Post Anchor Ground Spikes for 4x4 Posts — 2-Pack Carbon Steel, Black Powder-Coat

Heavy-duty 22-inch ground spikes that securely anchor 4" x 4" (internal 3.6" x 3.6") wooden posts without digging concrete footings.

These CDFYJHFDQ fence post anchor ground spikes are carbon-steel post bases finished in an anti-rust black powder coat, built to hold pergolas, mailbox posts, signposts and other outdoor structures steady in soil or concrete. Each pack contains two anchors sized to accept 3.6" x 3.6" posts internally, plus the hardware and wrench you need for straightforward installation. They offer a quick, reusable alternative to poured concrete that minimizes site disturbance while delivering long-term stability.

How do these anchors install and how long does installation take?

Installation is simple and fast: drive the spike into the ground, set the post into the internal sleeve, then tighten the supplied screws. For compacted soil or shallow rocky ground you may need a mallet or post driver; in concrete placement, embed the spike before the concrete sets. A single anchor typically takes 10–20 minutes to install when ground conditions are normal.

• Drive-in method works for most soft to medium soils
• Includes 8 hex screws with spring washers, 16 flat head screws and a wrench
• No concrete mixing required unless extra hold is desired
• Quick swap or removal for seasonal projects

What are the product dimensions and material details?

Each anchor measures 22 inches overall with a 17-inch lower driven section and a 5-inch upper sleeve for post seating. The internal sleeve is sized at approximately 3.6" x 3.6" to accommodate nominal 4" x 4" wooden posts, and the body is formed from carbon steel with a protective black powder-coat finish to resist corrosion.

• Total length: 22 inches (17" lower + 5" upper)
• Internal sleeve: ~3.6" x 3.6" for 4" x 4" posts
• Material: high-strength carbon steel with anti-rust powder coating
• Sold as a 2-pack with mounting hardware and a wrench

How stable are these spikes for different outdoor uses?

When driven fully into suitable ground they create a rigid connection that resists lateral and uplift forces better than simple surface mounting. They’re ideal for lightweight to medium-duty structures like fencing, mailbox posts, small pergolas, bird feeders and temporary signage. For very tall, heavy, or high-wind installations consider supplementing with concrete or additional anchors for extra safety.

• Best for pergolas, fences, mailboxes, signs and garden posts
• Provides superior lateral resistance compared with stakes
• Can be embedded in wet concrete for maximum permanence
• Removable for seasonal projects or site changes

What hardware is included and what tools will I need?

The package contains two complete anchor spikes, eight hex screws with spring washers, sixteen flat-head screws and one wrench to tighten the fasteners. You’ll also want a mallet or post driver for driving the spike, and a level to set the post plumb. For concrete installations, a shovel and mixing tools will be necessary if you choose to pour around the spike.

• Included: 2 anchors, 8 hex screws with spring washers, 16 flat-head screws, 1 wrench
• Recommended tools: mallet/post driver, level, drill for pilot holes
• Optional: concrete and mixing tools for permanent installations
• Fasteners secure post to anchor from multiple sides for stability

Who is this for: Homeowners, landscapers and DIYers who want a fast, durable way to install 4" x 4" posts without pouring large concrete footings will find these CDFYJHFDQ ground spikes especially useful. They suit temporary and semi-permanent projects, rental properties that require non-destructive installations, and anyone seeking a neat, professional-looking post base that’s easy to remove or relocate.
