Review on Sunex 6602LP: High-Quality 2 Ton Low Rider Steel Service Jack for Efficient Lifting by Duane Kaul

I liked this jack so much I ordered a second one. Two minor issues: On one of them, the handle didn't rotate freely to open or close the valve. It seemed to me that the problem was in the paint, so I quickly laid it out on a workbench and rolled it, sanding the paint off with sandpaper on an angle grinder. The photos show the scratched problem paint and the polished end result. This completely solved the problem. Now the other jack was missing the bolt holding the handle to the base. I took a closer look at my other jack and can say that: an M12x1.75 screw. The length under the head is about 0.500 inch and the thread length is about 0.360 inch. Thus, the tip length is 0.140 inches and the tip diameter is approximately 0.260 inches. The photos show a Sunex bolt (silver) and one I took from a junkyard (black) and turned on a lathe to replace the missing one.
