Stainless Steel Alloy SS 321H fasteners are most widely used fasteners in corrosion resistant category. SS 321H fasteners are manufactured in wide range of bolts, screws, stud bolts, studs, threaded rods, nuts, washers & custom bolting parts. 321H stainless steel fasteners are exclusively produced in cold forged method under ASTM F593/F594 & BS EN ISO 3506-1/3506-2 specifications. Hot forged 321H stainless steel fasteners are produced under ASTM A182 F321H, F593 Grade B8 & A194 Grade 8 specifications. SS 321H fasteners are well suited for its general corrosion resistance and aesthetic appearance.
