Marine Fasteners for Shipbuilding and Offshore Applications
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.
- Stainless steel & alloy fasteners
- Superior corrosion resistance
- Custom solutions for shipbuilding
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).
What Fasteners Are Used in Shipbuilding?
Shipbuilding and marine engineering require fasteners that can perform reliably in one of the most aggressive environments—saltwater exposure combined with humidity, vibration, and mechanical stress.
Common marine fasteners include:
These fasteners are used in ship hulls, decks, engines, and offshore structures.
- Stainless steel bolts and screws
- Stud bolts and heavy hex bolts
- Marine-grade nuts and washers
- Threaded rods
- Custom fastening components
