Product Advantage
Made from high-grade 304 or 316 stainless steel, these shackles ensure excellent corrosion resistance, making them perfect for harsh marine, industrial, and construction environments. This durability extends their lifespan, ensuring you get the most out of your investment.
The hexagon pin design provides a secure fit, preventing loosening under vibration. This feature, combined with the polished finish, ensures smooth, rounded edges that protect ropes and cables from damage while offering a safer, more reliable performance.
These shackles are suitable for a wide range of applications, including marine rigging, lifting operations, vehicle recovery, and agricultural use. They provide secure and reliable connections for both heavy-duty and aesthetic applications.
Stainless steel is resistant to staining and pitting, requiring minimal maintenance. A quick rinse with mild soap and water keeps the shackles in top condition, ensuring hassle-free upkeep.

Product Operate Guide
Check for Damage – Look for cracks, deformations, or corrosion.
Verify Load Rating – Ensure the Working Load Limit (WLL) matches your application.
Inspect Threads – Confirm the hexagon pin threads are clean and undamaged.
Lubrication – Apply anti-seize grease (for marine/rust-prone environments).
Align the Shackle – Position the D-shackle so the load pulls straight (avoid side-loading).
Insert the Hexagon Pin – Hand-tighten first to avoid cross-threading.
Secure with a Wrench – Use a hex key or spanner to fully tighten (prevents loosening under vibration).
Check Fit – Ensure the pin is flush and the shackle moves freely.
Center Loads – Always apply force in-line with the shackle (avoid angular stress).
Avoid Side Loading – Can reduce strength by 50% or more.
Dynamic Loads? – Use a higher safety factor (e.g., 6:1 instead of 4:1).
Temperature Limits – Stay within -40°C to 400°C (for stainless steel integrity).
After Saltwater Use – Rinse with fresh water and dry.
Lubricate Threads – Prevents seizing (use marine-grade grease for 316 steel).
Store Properly – Keep in a dry place, away from chemicals.
FAQ
A:304 is great for general use in mild environments, while 316 offers superior resistance to saltwater, chemicals, and acids, making it ideal for marine and offshore applications.
A:Yes, provided it meets the rated Working Load Limit (WLL) and safety standards (e.g., DIN/ISO). Always inspect the shackle before use.
A:Tighten the pin with a wrench to ensure it's secure. For extreme vibration, use threadlocker or a safety wire to prevent loosening.
A:Yes! Hex pins offer superior grip and security, especially in applications subject to vibration.
A:The standard safety factor is typically 4:1 or 5:1. For instance, a 10-ton shackle will break at approximately 40-50 tons. Always consider dynamic loads for added safety.
