Most commercial stainless steel fasteners available are made with austenitic stainless steels (200-300 series). These are commonly known as 18-8 (304) and 316 grades. These grades are not that high in strength and should never be used in applications calling for grade 5 or grade 8 fasteners. In fact, they are in the strength range of grade 2 fasteners (approximately 75,000 psi).
