Marine Grade Nuts And Bolts

Marine grade nuts and bolts are generally manufactured from A4 or 316 stainless steel and are suitable for sea and coastal applications where stronger anti-corrosion properties are required. These materials have a higher content of nickel and molybdenum, making them less susceptible to crevice corrosion and pitting. The products included here are manufactured from these materials, and are generally intended for marine and boat maintenance use, but can be used elsewhere for any number of applications.
Fastener Material Key
A4 Stainless Steel - Also known as grade 316 or 18/8/3. A higher corrosion resistant, marine grade of stainless steel.
A4-80 Stainless Steel - Identical corrosion resistance to A4-70 but with a higher tensile strength equivalent to that of 8.8 high tensile steel.
Duplex Stainless Steel 1.4462 - A type of stainless steel which has greater corrosion resistance than A4 / 316 and a high tensile strength of minimum 700 N/mm2. Also known as 318LN.
