Insaga 30" Screw-In Ground Anchors 6-Pack — 12mm Solid Steel, 3" Spiral Blade

Insaga 30" ground anchors are heavy-duty, screw-in earth anchors built from 12mm solid steel with a 3" spiral blade and welded eye for secure, removable anchoring.

These anchors are designed to hold structures like mobile homes, sheds, trampolines, swing sets, carports, and temporary shelters in place by threading a deep spiral into the soil. Each anchor measures 30" overall with a 27.2" ground length, a 3" spiral diameter and a 20mm top ring; a 14mm socket is included for fast installation. The durable chrome-plate finish and fully welded construction increase corrosion resistance and improve the anchor's grip in many soil types.

How do these screw-in anchors install and remove?

Installation is straightforward: remove the eyelet, fit the included socket to an impact driver or wrench, and twist the anchor into the ground until the spiral is fully embedded. Removal uses the same socket—unscrew the eyelet and back out the anchor. This design makes relocation or temporary fastening convenient.

• Comes with a 14mm socket for power-driver or manual use
• Removeable eyelet allows quick driver attachment and detachment
• Spiral blade threads anchor into soil for strong lateral and uplift resistance
• Works with portable or permanent setups—unscrew and reposition as needed

What soil conditions suit the 3" spiral blade best?

The 3" spiral provides wide surface area to bite into loam, sand, and mixed soils; it performs especially well where a wider helical profile stabilizes loose ground. Extremely rocky or heavily compacted clay may reduce insertion ease and holding performance—pre-drilling or choosing a different anchor type may help in those cases.

• Ideal for sand, loam, and mixed garden soils
• Wider spiral helps in looser soils to resist pullout
• Rocky or dense clay may require pre-drilling or alternate anchoring
• 30" length increases embedded depth for added stability

How durable are these anchors and what protects them outdoors?

Insaga anchors are made from 12mm solid steel and feature a chrome-plate coating to resist rust and abrasion. Fully welded construction at the spiral and eyelet reduces weak points, while smooth edges around the spiral help avoid fabric or rope chafe when tied off. Routine inspection and occasional cleaning will extend service life in coastal or high-moisture environments.

• 12mm solid steel shaft for increased strength
• Chrome-plate finish reduces corrosion and surface wear
• Fully welded joints minimize mechanical failure risks
• Smooth spiral edges protect ropes, straps, and fabrics

How much equipment can one anchor support and when should I use multiple anchors?

Load capacity depends on soil type, embedment depth, and the direction of forces (uplift vs lateral). Use multiple anchors for larger structures, asymmetrical loads, or when local code/specifications require redundancy. Spacing and the number of anchors should match the manufacturer's recommendations for your equipment or be determined by a qualified installer for critical applications.

• Capacity varies with soil; use several anchors for heavy or large structures
• Even small trampolines or temporary carports benefit from 3–6 anchors for stability
• Follow equipment guidelines or consult a pro for permanent installations
• Anchors can be relocated easily if layout changes

Who is this for: Homeowners, landscapers, and installers who need reliable, removable ground anchoring for portable or semi-permanent structures will find these Insaga anchors practical. They suit backyard trampoline setups, shed and carport tie-downs, dog kennels, garden trellises, and temporary shelters where a sturdy, screw-in solution is preferred over driven stakes. If you require anchoring in extremely rocky ground or for critical structural loads, consult a professional for the right anchor type or installation method.
