Sea-Dog 3/8 Inch Galvanized Bow Shackle, Screw Pin
Sea-Dog 3/8 Inch Galvanized Bow Shackle, Screw Pin — Product description
This Sea-Dog bow shackle is the kind of galvanized steel hardware you reach for when you need a solid connection that shrugs off salt spray. The rounded bow shape handles loads pulling from a few directions at once, so it's a natural fit for anchor rode connections. The 3/8 inch screw pin threads out by hand when you need to reconfigure.
A bow shackle earns its keep at the working end of your ground tackle. This one from Sea-Dog connects your anchor chain to the rode, or your rode to the anchor itself, and the rounded bow gives the load room to shift as the boat swings without binding on the pin. That wider throat is why anglers and cruisers reach for a bow shape over a straight D-shackle at the anchor.
It's made from galvanized steel, so it stands up to salt and spray far better than bare metal. The 3/8 inch screw pin threads in and out by hand, which makes swapping rigs or breaking down the anchor setup quick work. One thing worth knowing: screw pins can back out under constant vibration, so if this one lives somewhere it'll shake for hours, mouse the pin with a bit of seizing wire and you'll never think about it again.
Beyond the anchor locker, it's handy anywhere you need a removable link. Blocks, towing bridles, flag halyards, deck gear. Sold as a single shackle.

Frequently asked questions
What's the difference between a bow shackle and a D-shackle?
A bow shackle has a rounded, wider loop (the bow) that lets a load pull from several directions at once without jamming the pin. A straight D-shackle is stronger for a single straight-line pull but doesn't handle side loads as well. That's why the bow shape is the usual pick at the anchor, where the boat swings and the pull angle keeps changing.
What size is the pin and the shackle?
This shackle uses a 3/8 inch screw pin and has a 9/16 inch ring (bow) size. Match the pin diameter to the chain or hardware you're connecting so everything seats cleanly.
Will the screw pin back out on its own?
It can under constant vibration. For anything that shakes for long stretches, run a short piece of seizing wire (mousing wire) through the pin eye and around the bow to lock it. In the anchor locker where it's mostly under steady tension, hand-tight is usually fine.
Is galvanized steel okay for saltwater?
Yes. The galvanized coating protects the steel from salt and spray, which is why it's a standard choice for anchor and rigging hardware. Rinse it with fresh water now and then, keep an eye on the coating over the years, and it'll give you a long service life.
