Fence Post Anchor Ground Spike Metal Black Powder Coated 24 x 4 x 4 Inches Outer Diameter (Inner Diameter 3.5 x3.5 Inches), Pack of 4

Spike is 18" so they drive into the ground easily. Spike/box welds look good and should hold up to snowplow hits. Road salt has been the demise of other spikes I've tried. The paint on these looks like it should resist corrosion for a while. 4x4 fits perfectly in the box. I don't use the tightening bolts since I sometimes need a quick mailbox swap after a snowplow hit. If I remember I'll update this post next Spring on how the spike performed.

With the hold of a sledge hammer or a rock, they go into the soil easily (I am 68 and could hammer them into the soil without asking for help, even clay). They come out easily for repositioning. They are sturdy, paintable and well worth the money. I used two for birdhouses, one birdhouse which was really heavy, and another one to attach a metal mailbox to for my garden area. I keep small handtools inside so I don't have to run around the house to the garage to get pruning sheers or hand shovels. These are so much easier to install than birdhouse poles and MUCH EASIER to level in all directions.

These anchors worked perfectly for holding 4x4's for a gate system. Simply pound in with 4x4 section inside or auger a starting hole, the insert.

The packaging was light considering the 4 of these are heavy. Our USPS delivery person left it in the rain and didn't ring the bell, so after 4 hours of rain the box was almost gone, I had to get each spike out and take it in. The spikes themselves are very good. Heavy coating and I think 2mm thickness steel. The four spikes are welded together below the 4x4 bracket in 3 spots. I thought they will not be sufficient but apparently they are.The 4x4 from Lowe's did not fit well , atleast not by hand. I pushed it in a little bit, and after that hammered the spike until the post went in all the way.The nuts needed 13mm socket. I did the first installation by putting spike in place, using level to push into ground, then hammering while checking level. This proved inefficient as one of the nut went into the ground and I had not put the post in yet. Also considering sometimes the posts don't fit well, it is good to put post in first, tighten, then hammer into ground. Also helps for the post level, since it can tied to the post now, and not just the spike.First 4 5 inches you can probably push with your body weight, after that I used a heavy piece of wood (approx 40lbs) I had and let it fall on the top of post a few times (since I don't have a sledge hammer) , no impact from a 16oz hammer after first 12 inches are pushed in.The posts are holding up great so far. I used almost 16 of these to build 90ft fence line and a gate. I also climbed on the fence rails to check if the whole structure wobbles or bends (Approx 170lbs). Will update after a few months , checking for any sagging or rusting.All in all, I did not want to work with concrete, and this is a faster and convenient process. (My legs hurt though , maybe sledgehammer would have been more useful) but they are 3 times more expensive than concrete mix. On a plus side, I guess I can pull them out later if I want to.Update: 10 Months since the installation. After two hurricanes, loads of rain and soggy weather they are still holding their place. Didn't check for rust, since I haven't pulled them out of the ground. My 80lbs dog likes to put his front paws on the fence and look over the fence almost everyday. Even after all this, there is no wobble or leaning. Waiting for winter to come around , hope it stands after the ground is frosted. They do go below the frost line in my region. Make sure you get longer spikes if you are in North.

Easy to use..repurpose some fence posts

Instead of digging all the fence post holes I used these.A.) I got more poles out of a 16' beam because the whole pole was above ground.B.) Didn't have to auger holes. Hammered them straight down.Warning: don't try to break rocks. These are aluminum. Move them half a foot up or down the line. Big rocks will bend these. They're not steel. But they're good for what they are if you use your brain and do it nice and easy.

I have used these as part of my perimeter fence, the base for chicken coop posts, and the base for pergola post. The stand alone post work well for my 5ft fence. Some wood post were easy to fit and some were not. One batch of 4x4s I got from home depot were not fully dried out, and they would not fit into these spikes easily. I didn’t think it would be a problem until I tried using them. That was only 3 4x4s out of the 15 4x4s I used with these.Using the spikes as the base for my chicken coop and pergola post was easy! Unfortunately I had to move my pergola a couple of months after I built it. Removing the spikes was a little difficult, but no where near as hard if I had to dig up the post. I will definitely use these again for future products

First, since fence posts are NOT cut to exacting standards, the opening should be slightly larger than 3.5" to avoid problems, which I ran into with 1 of the 4 posts I was using. Second, 18" is a long way to drive these in the ground. Some soils just wont take it. I gave up after killing myself to get them in 13". They are still plenty sturdy enough for my purpose. If people are using these for a full blown fence then they probably need to get them in the full 18".

Bought this for a project and never used it. Kept it anyway for future use. Very well made.

Great value.

Just what we needed to build our arbour

Received as ordered, Great.
