Dolibest 30" Screw-In Ground Anchors Set of 4 — Heavy-Duty 3" Spiral, Chrome-Plated

Dolibest 30" heavy-duty screw-in ground anchors are fully welded, 3" spiral earth anchors sold as a set of four to secure trampolines, sheds, mobile homes and other outdoor equipment.

These anchors combine thick solid-steel construction with a wide spiral and chrome plating to resist wear while delivering dependable holding power in a variety of soil types. Each anchor comes with a removable eyelet and a 14mm socket so you can drive them into the ground quickly with an impact driver or drill. The design focuses on deep embedment and a broad spiral to reduce pullout and lateral movement without relying on concrete.

How do these anchors install and remove?

Installation is straightforward: unscrew the eyelet, fit the supplied 14mm socket to an impact drill or driver, and rotate the anchor into the soil until the spiral is fully embedded. For removal or relocation, reverse the process by turning the anchor back out and reinstalling elsewhere.

• Use the included 14mm/0.5" socket with an impact drill for fast drive-in.
• Unscrew the top ring to attach the socket and speed installation.
• Reverse rotation to remove and reposition without digging.

What makes the Dolibest anchors strong and durable?

Each anchor is crafted from 12mm solid steel rod and fully welded spirals for maximum structural integrity. A chrome plate finish adds corrosion resistance for longer outdoor life while the 3" spiral diameter distributes load across more soil to resist pullout.

• 12mm (0.47") solid-steel core for heavy loads.
• Fully welded wider spiral for superior grip in soil.
• Chrome plating to limit surface rust and wear.

Which applications are these anchors best suited for?

These anchors are versatile for anchoring trampolines, swing sets, sheds, carports, mobile homes, and animal enclosures. They excel where a deep, screw-style hold is preferred over concrete footings and are useful for seasonal setups because they’re removable.

• Secure trampolines and swing sets to reduce tipping and shifting.
• Stabilize sheds, carports, and mobile homes in windy conditions.
• Anchor pet runs, chicken coops, trellises, and temporary structures.

What are the key dimensions and what tools do I need?

Each anchor measures 30" overall length with a 27.2" ground-embedded length and a 3" spiral diameter. The eyelet top is 20mm (0.8") and the included socket is 14mm (0.5"). An impact drill/driver is recommended for efficient installation, particularly in compact soil.

• Overall length: 30"; embed length: 27.2"; spiral diameter: 3".
• Top eyelet diameter: 20mm (0.8"); supplied socket: 14mm (0.5").
• Recommended tool: impact drill or driver for fastest results.

Who is this for: Homeowners, landscapers and installers who need a robust, removable anchoring solution for outdoor gear and light structures. If you want a heavy-gauge steel anchor with wide spirals for deeper bite and easier relocation, Dolibest’s set of four anchors gives a practical alternative to permanent concrete footings while delivering substantial holding capacity in many soil conditions.
