Antrader2 PCS Heavy Duty M12 Thread 2-Inch Adjustable Leg Leveler Carbon Steel Shockproof Self Leveling Feet - Base Diameter 3.1-Inch, for Workbench, Machine, Cabinet & Heavy Duty Applications, Black

Bought them for installing in a servers rack at an industrial facility. They are heavy (1 pound each approximately). Easy install and very impressed with support and stability. Great purchase.

I purchased D60 M12 60mm.I will be using them to make adjustable legs for a wooden desk in my camper van.4 stars because they appear solid, but the quality control could be improved. I ordered 4 of these (2 sets of 2) and two of the them had damage to the threads (circled in red in one of my photos). This damage caused the nuts to be difficult to get on and off. The undamaged threads were quite smooth. After tightening and loosening the nuts a few times it became a little smoother.Also the dimension in the photo says the bolt length is 2 inches, which is technically correct. However, you only get 1 inch of usable threads. This is because the bold goes up through the bottom and is held in place by the bottom nut which is permanently crimped onto the bolt. So if you need 2 inch adjustability, these will NOT work as they only expose 1 inch of thread.I purchased the uxcell M12x40x2.5mm Brad Hole Tee Nut to go with these so that I can mount them into the wooden feet of my desk. The tee nuts fit well on these.

Love it but I had to return I bought the size too big

They are good. the center bolt could be attached to the cup/foot better to keep it from spinning but once in place and tightened down, they dont move. I used them to level my metal lathe. In hindsight, I could have bought shorter ones as I didn't need as much adjustment as I first thought.

Ok, the feet are good size and well constructed but out of an order of two pairs, one pair didn't even come with the adjustment nuts, they were included with the other pair, that's a 50% failure rate so what gives?

Very happy with these leveling feet. I used them on a workbench build this summer. They are very heavy duty. I also bought some cheaper leveling feet for smaller benches that I built, but the quality doesn’t even come close. These feet are a little expensive, but they are totally worth it. I wish they came with t-nuts as well so I didn’t have to buy them separately (so many extras left over!)Great quality. They will probably outlive me.

Overall I am happy with it, although there always is room for improvement. Movers lost 3 levelers from Ping-pong table and manufacturer doesn't have the parts. This works like a charm for the most part. It would have been a 5 stars if not for the following : 1. Add M12x1.75 to the specs, I had to find it from Q&A. 2. Quality control can be better. 3 out of 4 legs work smoothly, but last one needs some work to square the thread, luckily it wasn't too much.

Fit my new sliding table saw perfectly, easily enabled proper levelling of the machine, and they look absolutely beautiful. Buying more. Excellent value!
