304 Stainless Steel S Hook | Marine Rigging Connector | sinofastener
304 stainless steel S hook manufactured per DIN 695 standard. Available in wire diameters from 2mm to 20mm, suitable for marine rigging connections, chain extension, and general hanging in engine room and deck environments. AISI 304 and AISI 316 grades available with polished or satin finish. Material certificates provided, third-party inspection supported.
What Is a Stainless Steel S Hook?
Astainless steel S hook is a simple bent-wire connector formed into an S-shape with open hooks at each end. It provides a quick, tool-free method for connecting chains, ropes, cables, or other rigging components. The open design allows fast attachment and detachment without additional hardware.
S hooks are widely used in marine, industrial, and general rigging applications. The 304 stainless steel grade provides good corrosion resistance for indoor and mildly corrosive environments. For saltwater or offshore exposure, the AISI 316 grade is recommended due to its superior pitting and crevice corrosion resistance from molybdenum alloying.

FAQ
Q: What is the difference between 304 and 316 stainless steel S hooks?
AISI 304 (A2) contains 18% chromium and 8% nickel, suitable for indoor and mildly corrosive marine environments. AISI 316 (A4) adds 2-3% molybdenum, providing significantly better resistance to pitting and crevice corrosion in saltwater and offshore conditions. For direct seawater exposure, 316 is the recommended grade.
Q: What standard governs S hook dimensions?
DIN 695 is the primary standard for stainless steel S hook dimensions, covering wire diameter, overall length, hook opening width, and bend radii. EN 10088 specifies the material requirements for A2 and A4 grades.
Q: Can S hooks be used for overhead lifting?
Simple bent-wire S hooks are designed for light rigging, chain connection, and hanging applications. They are not proof-tested or rated for overhead lifting of heavy loads. For certified lifting applications, use forged and proof-tested rigging hooks with a defined working load limit and safety factor.
Q: What surface finishes are available?
Standard finishes include polished (mirror) and satin (brushed). Polished finish provides maximum corrosion resistance and a clean appearance for visible applications. Satin finish offers a matte look with good durability. Custom finishes are available upon request.
