SS 316L Hex Bolts

An SS 316L Hex Bolt is a machine fastener with a hexagonal head and external threading, designed to be mated with a nut or a tapped hole to create a high-strength, non-permanent joint. The "L" designation signifies low carbon content (0.030% max), making the bolt highly resistant to carbide precipitation during welding. This characteristic prevents intergranular corrosion, which is crucial in severe, welded environments. Fabricated from Grade 316L stainless steel, the presence of molybdenum gives it exceptional resistance to pitting and crevice corrosion, especially in chloride-rich settings. Zeron Fasteners specializes in manufacturing and supplying high-quality SS 316L Hex Bolts, ensuring reliable and durable fastening solutions for marine, chemical, and pharmaceutical industries.
