Pole barn use
Worked as described. The video was VERY informative and necessary. They provided excellent vertical bearing but in my sand/clay there is more horizontal movement of my columns than I expected (application specific)

I ordered these to anchor a roof over a paver patio to cover my grill. I thought it would be less intrusive than to remove multiple pavers to dig and put in so no tubes. I was disappointed for several reasons. They are very hard to keep straight going down and once they start going crooked there is no real way to fix., even when using the rebar first. Also, even after using rebar to be sure there is a clear path, I encountered a rock or something down around 36 inches. Following the video, I used an 8 foot 2x4 to wind it into the ground. When the point encountered whatever was down there and I used a bit of force to clear it, the metal split on the top piece where it fit over the lower piece. I had high hopes, but ultimately wasted my time and money with this approach.

Hello Sir,
Unfortuantely we can't control what's in the ground or what could get on the way of the piles.
We will like to hear from you by email or over the phone : info@pylex.com or 800-264-1881.

Cheaply Made - Powder coating is awful.
Working on a project for a large outdoor pergola enclosed area & fence so i bought 16 of the adjustable screw piles from HD, as well as 32 of the lateral stabilizers to keep everything solid. Overall the piles work well and screw in fairly easily. Rocks can be a challenge but nothing a couple whacks with a sledge can't fix to break through the rocks. However, the issue i have with these products is the "Durable backed coating" is not at all true. I got 16 right off of a pallet at HD in what looked like their original packaging and they were already all scratched and chipped. The stabilizers i got new in box were all chipped and have large spots of coating missing. I got some very nice cedar to go with these foundations and adjustable supports and i was hoping it would look nice for years to come, but ive come to the realization that after probably 1 year the coating will already start to rust away and will look awful in no time at all. Extremely disappointed with the poor quality of these pylex products. Also, the hardware is all cheap zinc plated, not even galvanized which is only going to make the corrosion worse on the bad powder coating. I did get all new stainless hardware so atleast i can take it apart in a years time if i have to.

Hello Sir,
It is possible to see some picture of the screws piles and lateral stabilizers ? To be honest with you we never saw such situation in 23 years of existence, 1 or 2 pieces might be possible, but 16 of them. On the other hand we do sell 200 000 units in north america and never heard a story like yours before. I will like to know what happened so that this situation doesn't happen again. You can contact us by email or over the phone : info@pylex.com or 800-264-1881. Thanks Pylex
    Easy to use, cheaper and better then concrete
    I built a 14' x 20' deck last year and used 10 plyex 50 inch adjustable foundation screws each with the 24" extension. I used 5 screws per double 2x8 beam spaced at roughly 4' centres. I followed the instructions and used 4' lengths of rebar as a guide and this was helpful. My ground was mostly clay so it does take some effort to get them into the ground, I found that in some spots I would reach a point where it could not get the screw to go down any further. To get past these points I would give it a few good wacks with a sledge hammer and then kept screwing, this worked. I used the 24" extensions because I didn't know exactly how deep the clay layer was and since this is the first time using this product I wanted to be confident in the foundation. One year later and I can say with confidence that I made a good decision in using this as a foundation system. It was easy to install by myself, I didn't need to dig out footings for concrete or have heavy equipment install a helical pier. The deck has not moved at all. I have read some concerns with wind up lift, I also had concerns because the saddle does just sit on top of the post. I ran a bit of airplane cable through the pre-drilled hole at the top of the post and screwed the cable through the beam. For my deck design it is unlikely that wind would ever cause any uplift, but I felt safer doing this.

      Pylex screw piles
      Goes in easy, one man operation! May be hard to screw in rocky soil. Great to adjust deck levels even after it settles with frost. There is no way to tie down any structure unless you weld the screw brackets. Overall a better option to deck blocks!

      A decent solution for most applications
      I installed seven of these opposite a ledger board for a 8x35 replacement deck and found that these install pretty well. I live in Central Maine so we have a mix of clay rock and roots. Using a peice of scrap 4x4 and a sledge hammer to "encourage" past the occasional obstacle worked well for me in all cases - i did pilot my installation locations with 4' rebar as recommended to ensure i didn't have ledge or other obstacles in the way. I did have one unit that i believe the auger blade (aka the footing) may have broken off the pipe, but this was a low (18" off the ground) deck so i decided to just monitor for now and see if i have sinking in that location. Even with the pilot rebar i did find that most didn't go in "perfectly level" but was able to plumb the post fine. Code enforcement has already been out and inspected once and did not have any issues with helical pile installations for footings in my area. I'd recommend for smaller/lower deck applications only based on the potential auger failure i may have. Once you put in all of your beam and joist bracing i find all of the "movement" others have complained about goes away and you will be fine.

        Beware of rocks
        If your ground is sand you'll be fine. If you have rocks beware of this product. I was able to drive rebar into the ground for the screw to follow but when placing the screw into the ground i found a rock about 36-42" down that that auger head had trouble with (eventually passed). Trouble was the mounting head of the screw is cheap steel and split four ways. Tried a second one, same thing but this one only split into 3 pieces. Used one of the extension pieces and a monkey wrench to get it finally into place. Gets 2 stars as was able to use product eventually, had 4, only can use two of them now though due to broken heads on two of them.
          Worked better then expected!
          Used two of these at my back door to support a small deck. I had to install to a depth of 6 feet under ground. I used the 50" model with 24" extensions. I live in Manitoba and have mostly clay soil in my back yard. Luckily I did not come across any big rocks or roots. They both went in, in about 45 minutes. Saved me from having to rent auger and and pour concrete. Worked great!

            Easy to install and feels very solid
            Bought 6 this morning to use as the foundation for a 8x10 shed. Used a 2x4 as per instructions to screw into the ground. We used a level to ensure it would go down straight instead of using rebar cause we didn’t want to buy additional material. Seems like a much better solution for a shed foundation than concrete or gravel and way way easier and cheaper if you don’t have rock or boulders below grade.

              Worked great, just as advertised. Went in fairly easily, in part because I managed to avoid hitting any rocks, thankfully. Towards the end on one pier I found it stopped driving into the ground and just spun. Had the wife stand on the end to get it to bite into the ground again and was able to finish. Overall, was very happy I went with these as opposed to messing around with an auger / sonotube / conc.
