The Grade 80 Screw Pin Alloy Chain Shackle (SDS Type) is a high-strength, D-shaped lifting connector engineered for secure, straight-line pulls. Forged from premium alloy steel, it delivers exceptional durability and a superior strength-to-weight ratio for rigorous overhead lifting and industrial rigging applications.
*D-shape for in-line tension, Screw pin for quick assembly
A: A Chain Shackle (Dee) has a straight "D" shape best for single-leg lifts. Anchor shackles have a bowed shape allowing for multi-leg rigging. The SDS Type is a Chain Shackle designed for straight-line pulling.
Q: Can I use Screw Pin Shackles for permanent installations?A: No. Screw pins are for temporary use. For long-term or permanent installations, use a Bolt Type Shackle with a cotter pin to prevent the pin from backing out due to vibration.
