600pc Assorted Box of UNF Steel Nuts - 600 steel hexagon full nuts in UNF fine thread, covering the four most used imperial sizes from 3/16" through to 3/8".
UNF is the fine imperial thread found across classic cars and motorcycles, older machinery and plant, and anything built to imperial sizes before metric took over. The finer pitch holds better under vibration than a coarse thread, and having the four working sizes boxed together means the right nut is on the shelf rather than on order.
