Din975 threaded rods (studding) are bars of metal that have been threaded to accept nuts and washers in a range of standard sizes. Threads maybe cut on nominal diameter or rolled on pitch diameter material. The threads have no set start point so a nut will be able to be threaded onto the rod from a freshly cut end. Standard: DIN, ANSI, BSW Thread type: Coarse or fine, inches or metric. Material: Carbon steel, alloy steel, aluminum, brass or stainless steel.
