Anfeng Lifting & Rigging introduces its premium Screw Pin Shackles, engineered to deliver exceptional strength, safety, and versatility in heavy-duty lifting, rigging, and towing operations. Designed and manufactured in full compliance with ASME B30.26-2004 and RR-C-271D standards, these shackles are trusted across industries including construction, marine, oil & gas, and general industry.
Crafted from high-quality carbon steel (bow) and alloy steel (pin), each component undergoes rigorous quenching and tempering processes to achieve superior toughness, fatigue resistance, and structural reliability. The large rounded bow design efficiently distributes multi-directional loads, reducing stress under angular lifting conditions. A hot-dip galvanized finish provides outstanding corrosion resistance, while the bright yellow-painted pin enhances visibility and operational safety.
Key Features & Benefits:
-
Exceptional Load Performance: Proof load tested at 2x the Working Load Limit (WLL) and a minimum breaking load of 6x WLL, ensuring a high safety margin for critical applications.
-
Durable & Corrosion-Resistant: Hot-dip galvanized bow offers long-lasting protection in harsh or outdoor environments, including marine and offshore settings.
-
Easy & Secure Use: The screw pin mechanism allows for quick attachment and detachment while maintaining secure load retention under dynamic conditions.
-
Wide Compatibility: Ideal for use with wire ropes, chains, synthetic slings, and other rigging hardware.
