Our screw pin shackles are engineered for superior strength, durability, and versatility in heavy-duty lifting and rigging applications. Designed with a large rounded bow shape, these shackles efficiently handle multi-directional loads while minimizing side load stress. Manufactured from high-quality carbon steel (bows) and alloy steel (pins), each shackle undergoes quenching and tempering for maximum toughness and reliability.

Compliant with ASME B30.26-2004 and RR-C-271D standards, these shackles are ideal for construction, marine, oil & gas, and industrial lifting operations.

Key Features & Benefits

1. Robust Construction for Heavy-Duty Use

• Quenched & Tempered Carbon Steel Bow – Ensures high tensile strength and resistance to deformation.
