Answer: 
I think they would work very well. We use them on signs that stand 8 feet high, and they have always been rock solid.

Yes, these will handle all the horizontal load you can put on them, and will anchor posts in place to keep them from moving. Note that these are meant to hold 4x4 (wood) posts, and as such the interior is just bigger than a 3.5" x 3.5" square. For proper support, anything you insert into the anchor should fill that interior square as much as possible. If your play set is a wooden climber, you should be Read More
Yes, these will handle all the horizontal load you can put on them, and will anchor posts in place to keep them from moving. Note that these are meant to hold 4x4 (wood) posts, and as such the interior is just bigger than a 3.5" x 3.5" square. For proper support, anything you insert into the anchor should fill that interior square as much as possible. If your play set is a wooden climber, you should be fine in terms of anchoring, but if it is tubular steel, it is not. Please note that the top 8 inches or so of the anchor remains above ground (there is a support structure/flared skirt type of partial plate preventing you from driving it further into the ground), so you will have rigid metal edges sticking out of the ground, and you'll be driving in some type of large head screws through that metal to attach the wooden post to the anchor. All of that metal may not be child/fall friendly unless you plan to cover it with a padded or rubber boot for safety. Read Less

Answer: 
No screws are provided. Must use appropriate screws for the application, i.e. size and type of posts used & indoor or outdoor (We use 4'X4" posts, cured and non treated, outdoor - so chose to use low rusting screws at least 2.5" long). Ozco, manufacturer, can give you pointers also, on types of screws to use.

Rated 4.3 out of 5 by 72 reviewers.
Rated 5.0 out of 5.0 by worked well we used theese to put up some privacy fence posts between trees and several bushes along with posts buried in the ground. After locating a spot between all the really large roots we used sledge hammer to install anchor. We did have to make a metel plate to fit in bottom of the square part that holds the post to be able to use a scrap 4 by 4 to drive anchor in to ground. Other wise you would just be driving the scrap 4 by 4 down into the anchor tearing up 4 by 4 and getting it jammed in it. They should be solid inside or come with removable plate. Unless your ground is really soft you cannot install theese without the plate. A little difficult to keep plum but it worked out ok for us. August 11, 2016
Rated 4.0 out of 5.0 by good for a one person job Bought OZ-Post to put up a fence. And since I was doing the job solo, I figured this method would be easier than using an auger. And they were easier. The down side is that the quality of the product isn't quite where I would like it. The anchors, if they are not close to perfect, will twist as they are pounded in the to ground. So you take all this time to make sure your spacing is correct, that your path is straight and true, but then your end up with posts that are not square. I tried several different methods so that they would finish square, but none were really successful. Being super detailed, this really bothers me. Secondly, while I feel these will be sufficient for my fence, perhaps it is the nature of a horizontal fence, or the fact that my post are not set in 24-36 in of concrete, but the fence does not have the lateral strength of standard concrete posts. Lastly, particularly if you are building a horizontal fence, you have to come up with a method of covering the part of the anchor that is above ground. May or may not be important to others. I would use them again if going solo, or needed a job done super quickly, Otherwise I think I would go with standard concrete posts. August 30, 2016
Rated 5.0 out of 5.0 by Excellent concept executed very well These aluminum "post holes" are really good labor savers by avoiding digging post holes. They are better in frozen ground conditions in that the frost layer does not push the posts out of the ground. Need to have strong arms to drive them in manually, or a jack hammer. Need to drill pilot holes for them when the ground is frozen - much easier than drilling large post holes. Have been using them for past two years to professionally install signs - not a single failure when used properly except for one bad batch. Manufacturer replaced whole batch plus a few more to compensate for our problems. Saves us lots of time and effort. Have well over 200 installations using them. Good product. January 5, 2016
Rated 5.0 out of 5.0 by Better than Concrete Used these anchors after my original cemented posts rotted out. Rented a jackhammer to install 25 anchors. Was done in about an hour and a half. These anchors are holding up a six foot privacy fence. Had withstood winds in excess of 70 mph during a recent storm and didn't budge. August 16, 2016
Rated 5.0 out of 5.0 by great idea The post are great! however if your yard has hard soil, rocks, or roots...it can be a bit frustrating. I recommend you testing where you are going to place them first...otherwise you will be digging. These are a wonderful idea if your soil is fairly easy. I love the idea, and will buy more. June 28, 2016
Rated 4.0 out of 5.0 by Great product and time saver I love this product's ease of use and durability. If installed correctly it will save you a ton of time putting up your fence. Two things to remember are you need to make sure you are getting the correct Oz post for the posts you choose there are ones for finished and rough. And get the Jack hammer. I also wish they had them in store. Don't settle for imitators! June 21, 2016
Rated 5.0 out of 5.0 by Great Alternative and Solid i had a small back yard to re-fence and I was not looking forward to hand digging 25 post holes. I ran across this product and read the specs off their site and gave it a try first on a small area. Texas soil in my area is about 18" sandy loam and below that hard black clay. This company is based in Texas and they rated the fence at standing up to 120mph winds for 5 minutes with out issue. I can't testify to this but I can testify that once you drive these things in there is no easy way to get them out except digging them out or heavy machinery to pull them out. The product was well thought out and constructed solid. I have recommended it to several friends and they are looking into using them. They are a great alternative to hand digging post and guaranteed to last a lot longer. May 17, 2016
Rated 5.0 out of 5.0 by Oz-post two thumbs up First time using Oz-posts. Definitely would use them again. Drives good in dirt - tougher in rock. Overall quality product. July 5, 2016
