Quick verdict
A hundred 8 inch spiral-shafted plastic spikes that pin weed barrier fabric, paver and landscape edging, artificial turf and drip lines to the ground. The spiral grips soil better than a smooth shaft and the plastic will not rust or stain paving. They push into soft soil by hand and need a mallet in firm ground. A hundred is enough for a patio edging job or a large fabric area. In hard clay or stony soil, use steel pins instead.
Strengths
- Spiral shaft resists pulling out far better than smooth pins
- UV-resistant plastic will not rust or stain
- Eight inches reaches below the loose surface layer
- A hundred spikes covers a large area of fabric or a long edge
- Safe to mow over and trip-free when flush
Weaknesses
- Plastic bends or snaps in stony or hard-packed ground
- Not for anchoring anything under real load
- Heads can crack if hammered hard

Pins That Stay In
Weed barrier that lifts at the edges, paver edging that creeps and turf seams that curl all come down to anchors. Smooth plastic pegs pull out of soft soil; steel pins rust and stain. DharBnt’s spikes are 8 inches of UV-resistant plastic with a spiral shaft, which turns into the soil as it goes down and resists pulling out like a screw. A hundred come in the pack.
This review is based on the listing specifications and on how spiral plastic landscape anchors perform generally. We have not used these spikes ourselves and the brand is a generic importer.
The Spiral
A smooth shaft holds by friction alone and loosens as soil shifts and frost heaves. A spiral shaft has soil above every turn, so pulling it out means lifting that soil. In sandy and loamy ground the difference is large and the spikes stay flush for years.
Plastic
No rust means no orange stains on pavers and no corroded pins to find with the mower. UV resistance keeps the heads from going brittle in sun. The limit is strength: plastic bends or snaps in stony or baked clay soil and the heads crack under a steel hammer. Water hard ground first and use a rubber mallet.
Uses
Pin landscape fabric every 3 to 4 feet along edges and overlaps. Hold plastic or aluminium paver edging every 2 feet through its anchor slots. Fix artificial turf edges and seams in a soft base. Secure drip tubing, bird netting and frost fleece. For edging under tension or turf in heavy traffic, add galvanized steel pins at the stress points.
Quantity
A hundred spikes pins about 300 feet of fabric edge or 200 feet of paver edging, which is a full patio or a long bed. Spares are useful for the netting and tubing jobs through the season.
Who Should Buy It
- Anyone laying weed barrier under mulch or gravel.
- Patio builders fixing paver edging restraint.
- Gardeners pinning netting, fleece and drip lines.
Common Owner Complaints
Spikes snapping in hard or stony soil. That is a soil match issue; use steel there.
Installation Tips
Push spikes in at a slight angle away from the direction of pull so tension seats them deeper rather than levering them out. On fabric, pin the overlaps first and the edges second, pulling the fabric taut as you go so it does not ruck under mulch. In sandy ground, a few spikes driven through a scrap of edging or a washer spread the load and stop the head pulling through.
Removal and Reuse
The spiral that holds them in also lets them unscrew: twist as you pull and they come out clean for reuse. Spikes left in for years stay serviceable as long as the heads have not been chewed by a mower.
Alternatives to Consider
Galvanized 6 inch U-pins for hard soil and turf. Steel paver edging spikes for restraint under load. Biodegradable stakes for temporary fabric on slopes.
Verdict
In soft and ordinary soils, spiral plastic spikes hold fabric and edging better than smooth pegs and never stain, and a hundred for this price equips a whole project. Keep steel pins for the hard ground.

DharBnt 100 Piece 8 Inch UV-Resistant Plastic Spiral Landscape Edging Spikes FAQs
Plastic in soft and sandy soil where rust stains and mower damage matter. Steel in clay, stony ground and anywhere the fabric or edging will be under tension.
Every 3 to 4 feet along fabric edges and every 2 feet along paver edging, closer in wind or on slopes.
Water the ground first and use a rubber mallet with light taps. A hammer cracks the heads.
Along edges and seams in soft base, yes. For high-traffic turf, galvanized U-nails are stronger.
