Insulation/corrosion-resistant bolts ideal for preventing galvanic corrosion during dissimilar metal bonding.
The "SDC anti-corrosion bolt" features a surface treatment with SDC color on stainless steel (SUS304/316(L)) that excels in corrosion resistance, preventing chlorine-based corrosion in seawater, and provides insulation effects through the resin coating of the bolt and the glass fiber reinforced resin washer. It prevents galvanic corrosion when joining dissimilar metal pipes such as stainless steel and ductile iron pipes. It maintains high corrosion resistance, making it ideal for use in seawater environments (such as reclaimed land) and in seawater itself. 【Features】 ○ Prevents galvanic corrosion during dissimilar metal joining ○ Prevents pitting corrosion occurring in seawater and chlorine-based solutions 【For more details, please download the catalog or feel free to contact us】
