A mounting system for a shipping container or trailer floor having a plurality of apertures positioned to align with mounting holes of machinery having a first diameter to be mounted to the container floor, wherein the diameter of the container floor apertures are larger than the first diameter to allow a margin of error in the alignment with the machinery mounting holes. Non-circular threaded fasteners are located on the bottom surface of the container floor for receiving bolts for mounting machinery to the container floor, and a plurality of non-circular edged bases, each sized for receiving a non-circular threaded fastener such that the non-circular threaded fastener cannot rotate within non-circular edged base. The system also collects spilled machinery liquids for later removal.
