Stainless Steel JIS D Shackle

The JIS Type D Shackles, classified as SC (standard type with captive pin) and SB (bolt type with nut and cotter pin), are essential components in marine, rigging, and industrial lifting systems. These shackles are manufactured from high-grade stainless steels (SUS304 and SUS316), offering superior corrosion resistance in harsh environments such as saltwater, chemical plants, and outdoor construction sites.

Design & Functionality:

• SC Type (Captive Pin): Features a fixed-thread pin ideal for semi-permanent installations where ease of use is critical and pin loss must be avoided.

• SB Type (Bolt with Nut and Cotter): Designed for enhanced security in dynamic or high-vibration applications. The nut and cotter pin lock the bolt in place, minimizing the risk of accidental disengagement under load.

Technical Highlights:

• Sizes range from 6mm to 24mm diameter (D), accommodating various rigging requirements.

• Working Load Limits (WLL) span from 1.96kN to 35.28kN, ensuring suitability across light to heavy-duty applications.

• Thread diameters scale with size, with both types providing metric threads for compatibility with standard tools and fittings.

Applications: These shackles are used extensively in lifting slings, mooring systems, marine rigging, and structural support assemblies where strength, durability, and corrosion resistance are paramount.

Use Cases:

1. Marine and Offshore Applications:
   These shackles are widely used in sailboat rigging, anchor chains, mooring lines, and offshore equipment due to their resistance to saltwater corrosion. The SB type, with its bolt-and-cotter locking mechanism, is especially suited for high-vibration environments like ship decks and offshore platforms.

2. Construction and Lifting Equipment:
   JIS D Shackles are commonly integrated into lifting slings, hoisting systems, and temporary bracing structures. Their standardized sizing and high working load limits ensure compatibility with cranes, rigging blocks, and chain assemblies for safe vertical and angled lifting.

3. Industrial Machinery and Structural Assemblies:
   In factories and structural installations, these shackles serve as reliable connectors for tension cables, pulleys, and adjustable supports. The SC type is favored where quick assembly and disassembly are needed without sacrificing strength, while the SB type is used in more permanent or critical-load installations.

Whether securing a load for transport or integrating into a fixed rigging system, JIS D Shackles deliver proven reliability and compliance with Japanese Industrial Standards, making them a trusted choice for professionals worldwide.
