What's the biggest nuts and bolts you've ever seen? A while ago someone asked what the biggest press was. Russia has a 75,000 metric ton forging press, that's 165 million pounds!!! Among the parts it produces are titanium aircraft components for the Airbus A380. The largest presses in the US are 2 seperate 50,000 ton(100 million lbs) at seperate locations. They were both part of a US heavy press program in the early to mid 50's. The Mesta machine operated by Alcoa needs repairs estimated around 68 million dollars. The machine has some threaded columns that are 40 inches in diameter with 52 inch diameter nuts. The heaviest of the nuts are 55 tons or 110,000 pounds each!!! Hard to fathom how big the wrench was to tighten them or what they were torqued to??? LoL Dave
