Chumia ground anchors 12-pack 18-inch spiral earth anchors — heavy-duty steel with driver bit (Green)

Chumia ground anchors are 18-inch spiral-blade steel stakes sold in a 12-piece kit with a power nut driver bit, designed to firmly secure trampolines, sheds, tents, canopies and trees in soft or medium soil.

Whether you're stabilizing a trampoline against gusts, anchoring a pop-up canopy for an outdoor event, or securing a garden shed, these screw-in earth anchors deliver deep holding power without complex installation. Built from thick steel with a spiral helix and a solid shaft, the set balances strength and corrosion resistance so it performs season after season. The kit supplies a full dozen anchors plus a driver bit sized for fast, repeated installation with a drill.

How do these anchors hold securely in soil?

The 18-inch length and wide 7.1 cm helix create strong lateral and pull-out resistance by displacing soil below the surface. The spiral blade bites into earth to form a stable, embedded anchor point that resists uplift and side loads.

• 18 inches (46 cm) length for deeper soil engagement
• Approx. 7.1 cm (2.8 in) helix diameter for increased holding area
• 10 mm solid steel shaft for tensile strength and durability
• Spiral design reduces loosening under load or vibration

Will these anchors withstand outdoor conditions and heavy use?

Manufactured from quality steel with an anti-rust finish, the anchors are made to resist corrosion and retain form through repeated seasonal exposure. While not stainless steel, their coating and robust construction minimize bending, breaking, or significant degradation in typical garden and recreational applications.

• Durable steel core to resist bending under load
• Colorfast, corrosion-resistant finish for outdoor longevity
• Designed for repeated installation and removal
• Suitable for soft to medium soils; avoid very rocky ground

How easy is installation and what tools are required?

Installation is straightforward: you screw the anchor into the ground using the included power nut driver bit and a compatible drill, or turn by hand if preferred. The driver bit speeds up insertion, especially when installing multiple anchors or working in compacted soil.

• Kit includes one power nut driver drill bit sized to fit the anchor head
• Install with a cordless drill for fast results or hand-turn for fine positioning
• No digging or concrete required — screw directly into soil
• Removeable and reusable for seasonal storage or relocation

What uses and load types are these anchors best suited for?

These ground anchors are versatile for a wide range of outdoor securing tasks where pull and uplift resistance matter more than permanent concrete footing. They're optimized for temporary and semi-permanent installations around gardens, recreational equipment, and lightweight structures.

• Trampolines and trampoline tie-downs
• Pop-up canopies, tents, and camping shelters
• Sheds, carports, fence posts and light structures
• Anchoring trees, garden fixtures, pet houses and outdoor furniture

Who is this for? The Chumia 12-piece earth anchor kit is aimed at homeowners, event organizers, landscapers and campers who need a reliable, portable anchoring solution that installs quickly without concrete. Buy this set if you want a practical all-purpose ground anchor supply for seasonal setup, multiple tie-down points, or to replace unstable stakes with a more robust screw-in option. If your site has very rocky soil or requires engineered permanent footings, consult a local installer for heavier-duty foundation solutions.
