Most of the jack posts I've seen have very thin metal base and top plates. These posts have thick metal plates and are very solid. I'm in the process of rebuilding a rotted porch and using one to support a beam. I have no doubt it'll last many years.

Good product

We have a small, old rental house with sagging / uneven floors, a small horizontal crack on the center floor beam from an earthquake, and shifted sill plate. Bought 8 of these screw jacks to support the droopy areas and lift others areas so we could insert reinforcing beams and attach plates to secure things. Some of these will be left in place permanently, others were moved around as needed. They are easy to use, the top plate pivots a little bit which helps account for slight uneven surfaces (like gravel beneath); there are holes to secure the top and bottom of the screw jack to the beams if desired. We had no problem with the bar used to turn the screw - I would say if yours bends, you are trying to lift more than these are designed for. Ours is a small house (1 story, 900 SF) and we could noticeably lift the house 1/4 (it changed door alignment). The floors feel much less bouncy now, and I feel better knowing there is additional support.

It did what I paid for. Good quality. Lubricate the threads and connections at the base and sill plate so that it turns nicely - if not, they will turn and it'll be a pain.

Would have been better if I got the ones I ordered, but these worked just took longer than would have if I would have gotten the correct ones. Was in a time crunch and could not return had to use what I had

Worked perfectly for the job.

It's all welded construction makes it easy to move around and adjust. The top plate is swaged on and rotates to adjust. It's made from 1/4 inch steel plate. I've used other jack stands but this is the type I'll always use from now on. I drug 4 of these through the dirt under a house and they still operated easily. This is not a lifting jack. The turn bar is for adjusting, not turning to lift. It can bend if you push hard enough. You need to jack up the beams first and use this to support the weight. You get what you pay for. Well worth the money.

Very stable

heavy duty and well made. Well designed even in crawl space with an uneven floor and tight work spacd.

High quality construction...and ready for use right out of the box. Real work/time saver.

Mine's the 12” version. It's a stout little guy perfect for raising the side of my porch enough so I could replace a post.I saw some reviews that said the turn-rod wasn't up to the task and had bent on them. Maybe their load was way heavier than mine but I had no problem. It takes effort of course to lift part of a structure but slow turning didn't feel like it came close to bending the rod. Only needed to raise the beam an eighth inch or so to get the old post out, and that's what these things are made forlifting a big weight a short distance.Very pleased with the quality and glad I selected this one.

These jacks worked great to stabilize my floors. Very heavy duty. I installed them in my crawl space under my washer dryer and my utility room. I noticed a big difference.

Sturdy and very functional for installing new supports under my house. Bolts are not included.

works well and easy to use.

I am using these to permanently fix my movement in the floor of my 60yr old house. They are working great! Sometimes you also need a hydraulic jack to raise a beam that is supporting a lot of weight. Other times you can put 2 close together and work off of each.

My sagging floor problems created by a thousand pound upright floor safe is cured. I placed theses underneath the floor and completely fixed my problem.

These are perfect and sturdy jacks for a great price. Use these for a sagging floor that I had easy to use and install just putting in place crank them up and you're done. They are very well made no complaints

To hard to turn with weight on it
