What is the recommended method to secure the pin to the shackle body?

• A. Tie Off With Rope
• B. Tie Off With Tape
• C. Tie Off With Zip Ties
• D. Tie Off With Wire

Answer: (D)

Securing a pin to a shackle body is about preventing the pin from backing out or rotating during use, especially under dynamic loading. The most reliable way is to tie off with wire because it creates a strong, continuous restraint that resists loosening even with vibration, impact, and repeated bending. Wire can be twisted and threaded through the pin and shackle body to lock the pin in place, and it remains visible for inspection for fatigue or corrosion. Rope, tape, or zip ties can loosen, degrade, or fail under tension, heat, or abrasion, making them unsuitable for a load-bearing connection. For safety and durability in lifting applications, wire provides the secure, inspectable method to keep the pin secured.
