Screw Jacks

Sometimes, equipment that we used need to be handled carefully, too. But if it is damaged, it's either you replaced it or fixed it. Anyway, accessories like screw jacks are very important also because it helps move up and down of the threaded cylinder when its handle is turned. So, imagine if there is no accessory like this, I'm sure you can't proceed to the next step of what you're doing.
