- Description
303 stainless steel unkeyed shafting is a smooth, precision-ground round bar without any pre-cut keyway, giving designers full flexibility to add custom slots, flats, or fastening features. Because 303 is optimized for machinability, it responds well to post-processing operations such as cutting, milling, or slotting, enabling precise modifications with relative ease. While 303 maintains respectable corrosion resistance in mild environments, it is susceptible to pitting in chloride-heavy or marine settings and thus is less robust than higher-corrosion grades. Its smooth unkeyed form is ideal for applications where alternative fastening methods (set screws, clamps, adhesives) are used or where custom keying will be done in-house.
