At one plant we did electrical work for we used speeder handles to open explosion proof electrical enclosures. They had many 1/2" bolts along the edges of the door to seal them shut. It was Quite a job to get one open. I have two Craftsman 1/2" drive and a Snap-On 3/8" speeders. I have used them to dissemble engines and too run down bolts during engine assembly.
