D-Shackle M4–M10 — A4 316 Marine Grade Stainless Steel

Heavy-duty D-shackle in A4 (316) marine grade stainless steel — engineered for rigging, lifting and load-bearing applications where corrosion resistance is critical. The straight D-profile delivers maximum strength along the loaded axis, with a captive screw pin for secure, repeatable connections. Available in sizes M4 to M10 and pack quantities of 1, 4 or 10.

Why choose A4 316 stainless steel D-shackles?

Manufactured from A4 (316) marine grade stainless steel, these D-shackles offer superior resistance to saltwater, chlorides and harsh outdoor environments. The compact straight-sided design provides higher in-line load capacity than equivalent bow shackles — ideal for static rigging, anchor points and chain connections.

Sizes available

Choose from M4, M5, M6, M7, M8 and M10. Select the diameter to match your chain, rope or rigging hardware. Larger sizes offer greater working load limits for heavier-duty applications.

Pack options

Order singly for one-off jobs, in packs of 4 for multi-point rigging, or packs of 10 for trade and bulk projects.

Typical uses for D-shackles

Marine rigging and sailing hardware, boat anchor and mooring connections, lifting and load-bearing applications, chain and wire rope joining, outdoor and coastal installations, agricultural and industrial assemblies.
