One Stop OutdoorHeavy Duty (10 Count) - Round Metal Landscape & Paver Edging Anchoring Spikes, 12-Inch Length - Bright Spike Timber Nail, Tent Spike, Camping, Landscape, & More (10-Pack)

They did the job I needed

Used them on oak landscaping timbers. Predrilled 5/16 holes still drove in hard didn’t bend and it holds great.

A drill and some Gorrilla glue. Made a good expendable javelin head. Especially if you are throwing for distance and there may be rocks in the target area.

As expected

Purchased the 3/8" diameter 12" Spikes. Customer service responded to my inquiry very quickly prior to purchase. I took my 3lb hammer and pounded the 4 spikes into the Asphalt. The spikes are very sturdy and didn't bend even when hitting them at an angle sometimes. If you need to fasten something into Asphalt this is a very good option. It has a 3/4" head on it which is necessary if you don't want to be able to slip the item your fastening up & over the spike which would happen if you used rebar spikes which don't have a head.

I’m happy with these stakes. I had been using 5/16 inch stakes used for pitching a tent but these are much better.

I use them for landscaping spikes. They should last a long time they are heavy duty.

Easy to use and drive in. I would buy these again..
