ASTM A193 B8M Hex Bolts

ASTM A193 B8M Hex Bolts are premium stainless steel fasteners specifically manufactured for use in severe corrosive and high-temperature environments, particularly those containing chlorides. The B8M grade refers to Austenitic Stainless Steel Grade 316, which is alloyed with molybdenum to provide enhanced resistance to pitting and crevice corrosion compared to B8 (304 SS). These bolts are typically fully or partially threaded and are essential for securing flanges, valves, and fittings in marine, chemical processing, and pharmaceutical industries. B8M Hex Bolts are often paired with ASTM A194 Grade 8M Heavy Hex Nuts to form a complete, highly corrosion-resistant bolting assembly. Zeron Fasteners is a reliable manufacturer and supplier of these critical bolts, guaranteeing dimensional accuracy and the required solution-annealed and strain-hardened mechanical properties.
