### ⭐ Very Bad Quality, Not as Expected
*by B***H on 26 March 2025*

The product is of very poor quality and made of aluminum, which was not expected. It feels cheap and not worth the price. I want to return it immediately. Very disappointed!

### ⭐⭐⭐ Only Jacknut without screw
*by A***R on 25 November 2025*

Wrong discription on site,these are not with screw only Jack nut

### ⭐⭐⭐⭐ Screw rivet for metal work
*by A***D on 26 September 2025*

Fit finish is good, threads are good but no anti slip washer on back, to stop from rotating with screw, need to grip with plier.
