Stainless Steel Alloy SS 309S fasteners are most widely used fasteners in corrosion resistant category. SS 309S fasteners are manufactured in wide range of bolts, screws, stud bolts, studs, threaded rods, nuts, washers & custom bolting parts. 309S stainless steel fasteners are exclusively produced in cold forged method under ASTM F593/F594 & BS EN ISO 3506-1/3506-2 specifications. Hot forged 309S stainless steel fasteners are produced under ASTM A182 F309S, A193 Grade B8 & A194 Grade 8 specifications. SS 309S fasteners are well suited for its general corrosion resistance and aesthetic appearance.
