Wear-resistant and corrosion-resistant
Fasteners for Ships
Ships and marine engineering equipment are exposed to high humidity, high salt spray, and highly corrosive environments for a long time, which places extremely stringent requirements on the performance of fasteners.
Beyond Fastener provides high-strength, corrosion-resistant fastener solutions designed specifically for the marine industry, ensuring the stability and safety of hull structures, deck equipment, and mechanical systems in harsh environments.

Advantages
- Excellent Corrosion Resistance: Utilizes A4, 316L, 2205, and 2507 stainless steel or zinc-nickel alloy, Dacromet, and PTFE coatings to effectively resist corrosion from seawater and moisture.
- High Strength: Complies with international standards such as ISO 898-1 and ASTM A320, including 8.8, 10.9, and 12.9 carbon steel and stainless steel grades.
- Customized service: We can customize non-standard bolts, nuts, screws, washers and other components according to customer drawings and standards (DIN, ISO, ASTM, BS, JIS).
