Stainless Steel Omega Shackles 5–20 mm (8 Sizes Marine Bow Shackles)

Omega shackles in stainless steel are essential hardware for secure connections on boats and beyond. Crafted from premium AISI 316 stainless steel, they resist saltwater corrosion and will not rust or seize, ensuring long-term reliability in marine environments. The bow-shaped Omega design provides a wider opening to accommodate thicker lines, straps, or chain without chafing – unlike narrow straight (D) shackles. Each shackle features a threaded pin that locks securely yet can be easily removed when needed.

We offer these Omega shackles in a wide range of sizes – from 5 mm diameter, suitable for small boats and light loads, up to 20 mm, built for heavy-duty applications on large vessels or even industrial settings. This variety allows you to choose the exact shackle size for your requirements: whether securing an anchor, mooring a yacht, lashing down cargo, or even off-road towing. Regardless of size, all versions are designed for maximum strength and safety in use.

• 5 mm & 6 mm: Best for small dinghies, inflatables, or light-duty utility – ideal for securing light gear, flag halyards, or camping equipment.
• 8 mm & 10 mm: Common sizes for medium boats and sailboats – great for attaching anchors, chains, or towing small trailers.
• 12 mm & 14 mm: Rugged choice for large powerboats and sailing yachts – handles substantial loads for mooring, anchoring, or heavy rigging tasks.
• 16 mm & 20 mm: Largest sizes for the highest demands – perfect for big yachts, commercial use, or off-road recovery where maximum strength is required.
