316 Stainless Steel Shackle Corrosion Resistant Drop-Forged Marine Shackle for Rigging and Mooring

The 316 Stainless Steel Shackle is a high-corrosion-resistant connecting fitting designed for marine, industrial, outdoor, and general rigging applications. Manufactured from AISI 316 stainless steel, it delivers superior resistance to saltwater, humidity, and chemical environments compared with ordinary carbon steel or 304 stainless steel fittings.

The shackle body and pin are manufactured from Type 316 stainless steel, which contains chromium, nickel, and molybdenum. The addition of molybdenum significantly improves resistance to pitting and crevice corrosion, especially in chloride-rich environments such as seawater, coastal areas, and high-humidity installations. For this reason, 316 stainless steel is often referred to as "marine grade" stainless steel.

316 stainless steel shackles are commonly available in D-shackle, bow/anchor shackle, and twist shackle designs. The body is typically drop-forged for improved strength and dimensional stability, while the screw pin allows secure closure and repeated installation. Surface finishes usually include polished or passivated treatment, giving the shackle a clean appearance and helping reduce surface contamination during use.

• Excellent corrosion resistance in marine, coastal, and high-humidity environments
• Drop-forged 316 stainless steel body for reliable strength and durability
• Screw pin or twist pin design for secure fastening and easy assembly
• Smooth polished surface to reduce wear on ropes, chains, and straps
• Available in multiple sizes, typically from small diameters such as 4–6 mm up to larger industrial sizes
• Suitable for rigging, lashing, marine hardware, and general connection use

• Marine rigging: sailboats, yachts, deck hardware, mooring accessories
• Wire rope and chain connections
• Outdoor equipment, camping gear, and canopy installations
• Industrial fastening, maintenance hardware, and equipment attachment
• Architectural cable systems, garden structures, and general hardware distribution

316 stainless steel shackles are widely supplied in standard metric and imperial sizes. OEM packaging, private labeling, and custom specifications can be supported for distributors and industrial buyers.

Important: For load-critical applications, working load limits should be confirmed according to the specific size, pin type, and manufacturer specification.
