S360 316 Standard D Shackle — High-Security Marine-Grade Lifting Pin by Anzor

Meet the S360 316 Standard D Shackle from Anzor, a purpose-built lifting and rigging connection engineered for the harsh realities of marine work. Featuring a screw-collared locking pin and a dedicated pin-tie hole, this shackle keeps pins secured even under vibration, dynamic loads, and offshore motion. It’s not just a shackle—it’s a reliability upgrade for critical connections on saltwater rigs, offshore platforms, and wind-turbine towers.

Why this shackle stands up to demanding environments

• Locking pin with screw collar: The threaded collar ensures the pin stays engaged under vibration and heavy lifts, reducing the risk of accidental release during operation.
• Pin-tie access for security wire: A dedicated hole allows a security tie wire to be threaded, providing an additional layer of retention beyond standard threading.
• Marine-ready materials and finishes: Available in robust 316 stainless variants with an electro-polished (EP) finish for smoother contact surfaces, easier cleaning, and improved corrosion resistance in salt spray and coastal environments.
• DIN-aligned versatility: S360 offers AISI304/316 variants with forging options to meet diverse lifting and rigging demands while aligning with common DIN specifications.
• Enhanced corrosion protection: The 316 stainless steel construction, with optional hot-dipped galvanizing, delivers superior rust resistance in saltwater atmospheres.

Sizes, dimensions, and how to choose

Use the bore and body dimensions to ensure a clean, bind-free connection in your rigging plan. The S360 316 Standard D Shackle covers a range from compact to substantial capacities, with precise bore (øA), overall width (B), and body length (L) to fit your hardware geometry:

Who benefits from the S360 316 Standard D Shackle

Maritime operators, offshore crews, and wind-turbine technicians rely on durable, corrosion-resistant hardware in saltwater and high-humidity environments. Riggers, crane operators, and maintenance teams appreciate the pin-retention features that minimize rework or interruptions during lifts. Engineers and procurement specialists will value a robust, low-maintenance shackle with a clear security advantage for mission-critical lifting points.

Practical use and maintenance for longevity

• Pre-load check: Confirm the pin is fully engaged and the screw collar is tightened before loading a rigging system.
• Security wire integration: When required, thread a security tie wire through the dedicated hole to lock the pin in place beyond standard threads.
• Maintenance routine: Wipe the EP finish clean to avoid salt buildup; consider hot-dipped galvanizing in highly exposed coastal locations for enhanced rust resistance.
• Compliance check: Ensure the forged variant and DIN alignment match the system’s load ratings for safe, code-compliant lifts.
