I use these for leveling parts on my mill, and the fine thread adjustment makes dialing in height super precise. They're solid steel and feel like they’ll hold up to years of shop abuse.

Finally, a set of jacks that actually stays put under load; the fine-thread adjustment makes leveling a breeze. I used them to replace step blocks for a clamp kit setup and it saved so much time.

I've been using these for setup work on the mill and the fine adjustment threads let me level a workpiece to within a couple thousandths without fuss. They've completely replaced my stack of step blocks when I'm using a clamp kit, which is a huge time saver.
