The composition of Stainless Steel 305 includes a higher nickel content than the common 304 grade, which gives these nuts their signature characteristic of excellent work hardening resistance. This makes them less prone to becoming brittle during fabrication. Mechanically, they offer good overall strength and maintain excellent ductility, allowing them to be formed and tightened without compromising their integrity. This combination ensures a reliable, long-lasting hold in a wide range of conditions.
