Paul Bunyan Industrial Supply.
Story: I once represented a fastener manufacturer. They, somehow, made a nut to go on the propeller shaft of an ocean-going ship. It was hoisted in place with an I-beam welded in several places. The nut was hoisted in line with the shaft, a pile driver then turned the nut ever so litte. After a while, the nut was secured in place. Don't know how long it took but I'm sure the hourly wage folks liked it.
