Rigging Hardware 304/316Stainless Steel Hexagon Pin Polished D Shackle European Type D Shackle

1. Superior Strength & Durability

• Made from high-grade stainless steel (304 or 316), ensuring excellent resistance to corrosion, rust, and harsh environments (saltwater, chemicals, UV exposure).

• Hexagon pin design provides a more secure fit and higher load-bearing capacity compared to standard round pins.

2. Enhanced Safety & Reliability

• Polished finish reduces friction and wear, improving longevity.

• Smooth, rounded edges prevent damage to ropes, cables, or slings.

• Secure locking mechanism (threaded or captive pin) prevents accidental loosening under load.

3. Versatile Applications

• Ideal for marine, sailing, towing, lifting, and rigging due to high corrosion resistance.

• Suitable for construction, forestry, and industrial use where strength and durability are critical.

4. Aesthetic Appeal

• Polished finish provides a sleek, professional look, making it suitable for visible applications (e.g., yacht rigging, architectural uses).

5. Easy Maintenance

• Stainless steel resists pitting and staining, requiring minimal upkeep.

• Can be easily cleaned with mild soap and water.

6. Compliance with Standards

• Often meets or exceeds international standards (e.g., ISO 2415, DIN 82101) for quality and safety.

Stainless Steel Hexagon Pin Polished D Shackle – Operation Guide

1. Pre-Use Inspection

✅ 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).

2. Proper Installation

Step-by-Step Attachment

1. Align the Shackle – Position the D-shackle so the load pulls straight (avoid side-loading).

2. Insert the Hexagon Pin – Hand-tighten first to avoid cross-threading.

3. Secure with a Wrench – Use a hex key or spanner to fully tighten (prevents loosening under vibration).

4. Check Fit – Ensure the pin is flush and the shackle moves freely.

3. Loading & Usage Best Practices

✔ 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).

4. Maintenance & Storage

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.

1. What’s the difference between 304 and 316 stainless steel?

• 304 (A2): Good for general use, resists rust in mild environments.

• 316 (A4): Superior for saltwater, acids, and chemicals (ideal for marine/offshore).

2. Can I use this shackle for overhead lifting?

✅ Yes, if it meets rated WLL and safety standards (e.g., DIN/ISO). Always inspect before use.

3. How do I prevent the hex pin from loosening?

• Tighten with a wrench (hand-tight isn’t enough).

• For extreme vibration, use threadlocker or a safety wire.

4. Can I replace a round pin shackle with this hex pin version?

✅ Yes! Hex pins offer better grip and security, especially under vibration.

5. What’s the safety factor?

• Standard is 4:1 or 5:1 (e.g., 10T shackle breaks at ~40–50T).
