AISI 321 Fasteners

AISI 321 Fasteners

In the corrosion-resistant category, Stainless Steel 321 Fasteners are the most extensively used fasteners. Bolts, screws, stud bolts, studs, threaded rods, nuts, washers, and special bolting parts are all made using SS 321 fasteners. Under ASTM F593/F594 & BS EN ISO 3506-1/3506-2 requirements, 321 stainless steel fasteners are solely cold forged. ASTM A182 F321, A193 Grade B8, and A194 Grade 8 requirements are used to manufacture hot forged 321 stainless steel fasteners. The general corrosion resistance and beautiful look of SS 321 fasteners make them ideal.
