Stainless Steel Square Head Screw Pin D Shackle
The Square Head Screw Pin D Shackle shown above is a high-strength, corrosion-resistant rigging component, commonly utilized in marine, industrial, and lifting applications. Manufactured from SUS304 stainless steel, it offers excellent durability in harsh environments, including saltwater exposure.
Technical Features:
Design: The D-shaped body provides superior load distribution along the straight side, making it ideal for straight-line pulls. The square head screw pin ensures secure closure and easy tool-assisted tightening.
Material: SUS304 (AISI 304) stainless steel is known for its strong anti-corrosion properties, making this shackle suitable for both indoor and outdoor applications.
Thread Types: Threads vary by size, ranging from metric (M) to Whitworth (W) standards, ensuring compatibility with international rigging hardware.
The Working Load Limit (WLL) scales proportionally with the diameter and overall size. For instance, the QS-6 model with a 6 mm diameter has a WLL of 170 kgf (1.67 kN), while the QS-25, the largest variant, supports up to 2000 kgf (19.60 kN).
This type of shackle is typically employed in static load-bearing scenarios and should not be used for dynamic or shock loading unless specifically rated for such use. Proper installation torque and thread engagement are critical to maintaining load integrity.
Applications:
Marine rigging & sailing hardware
Industrial lifting setups
Construction site anchoring
Load securement in transport and logistics
For engineers and technical buyers, this shackle offers a balance of mechanical reliability and material resilience, ensuring long-term performance with minimal maintenance.
