About this item

  • No Dig, No Concrete – Easy Ground Installation – Our 4x4 fence post anchor eliminates the need for digging holes or mixing concrete. Simply place the ground spike at your desired location, insert a short piece of 3.5"x3.5" lumber, and hammer it into the ground. The 23-inch spike provides deep anchoring for superior stability, making it perfect for fences, mailboxes, decks, signs, and pergolas
  • Heavy Duty Carbon Steel with Rust-Proof Coating – Crafted from heavy-duty carbon steel with a durable black powder-coated finish, this post spike is built to withstand harsh outdoor conditions. The rust-proof and corrosion-resistant surface ensures long-lasting performance, keeping your fence posts secure and stable for years
  • Precision-Fit for Standard 4x4 Lumber – Designed to fit standard 4x4 wood posts (actual lumber size 3.5" x 3.5"), our post anchor features a 3.6" x 3.6" inner head that provides a snug, secure fit. The large diameter head maximizes ground contact and stability, preventing posts from shifting under wind, soil movement, or animal pressure

What types of products does FixTimber offer?

FixTimber offers supplies for repairing, reinforcing, sealing, weatherproofing, preparing, and finishing wood-frame homes. Our collections include wood repair compounds, adhesives, fasteners, structural hardware, exterior hardware, weatherproofing materials, finishing products, and repair tools.

How do I know whether a product is suitable for my project?

Review the product description, intended application, dimensions, materials, compatibility information, and installation requirements before ordering. If you are uncertain, contact us with details about your project and the product you are considering.

Are your products suitable for outdoor use?

Some products are designed for exterior applications, while others are intended only for indoor or protected areas. Check the individual product page for information about weather resistance, moisture exposure, temperature limits, and suitable surfaces.

Can I use these products for structural repairs?

Certain fasteners and connectors may be intended for structural applications, but suitability depends on the building design, load requirements, local codes, and installation method. Structural repairs should be evaluated and completed by a qualified professional when appropriate

How can I choose the correct size of hardware or fastener?

Measure the relevant lumber, opening, connection, or existing component carefully. Compare those measurements with the dimensions and specifications shown on the product page. Do not select structural hardware based on appearance alone.

Will product colors and wood finishes look exactly like the images?

Colors may appear different because of lighting, screen settings, wood species, surface preparation, and application method. Test stains, fillers, waxes, oils, and coatings on a small inconspicuous area before completing the entire project
