Drive-In Post Spike (Bolt Secure, Hot-Dipped Galvanised) provides a fast, no-dig way to install timber fence and gate posts in firm ground. The heavy-duty steel spike is driven into the soil to form a secure foundation, while opposing clamping bolts grip the post above ground for a rigid, twist-resistant hold. The hot-dipped galvanised (HDG) zinc finish delivers long-term corrosion protection and a clean, professional appearance. Key Features & Benefits No-Dig Installation: Drive straight into firm ground—ideal where excavation would disturb paving, roots or services. Bolt-Secure Clamping: Opposing through-bolts lock the post for a strong, twist-resistant connection. Above-Ground Protection: Keeps end grain out of standing water to help reduce rot risk. Hot-Dipped Galvanised: Thick zinc coating for durable outdoor corrosion resistance. Quick & Accurate: Use with a drive-in tool for rapid alignment and consistent results. Available Sizes To Suit Post Size (mm) To Suit Post Size (inch) 50 × 50 2 × 2 75 × 75 3 × 3 100 × 100 4 × 4 Product & Technical Details Type: Drive-in post spike (bolt-secure clamp) Material: Heavy-gauge steel Finish: Hot-dipped galvanised (HDG) Fixing Method: Drive spike into ground; clamp post with opposed bolts Applications: Fencing, light gates, pergolas, signage and garden structures Instructions for Use Mark the post line. Place the spike and start square to the surface. Using a compatible drive-in tool and sledge, drive the spike to depth, checking plumb frequently. Insert the post fully into the shoe; plumb and square it, then tighten clamping bolts evenly. Re-check alignment after initial settling; retighten during routine inspections. Limitations & Precautions For firm ground only; in soft/peaty soils or where high uplift/lateral loads exist, consider concrete-in or bolt-down solutions. Do not strike the shoe directly—always use a drive-in cap or tool to prevent damage. Cut post ends square and treat end grain with preservative before clamping. A robust, no-dig fixing that speeds up fence and frame installs—drive in, clamp tight and protect the post end above ground for a long-lasting, professional result. Hot-dipped galvanised for dependable outdoor durability.
