Sea-Dog 316 Stainless Bow Shackle, 5/16in Screw Pin
Sea-Dog 316 Stainless Bow Shackle, 5/16in Screw Pin — Product description
The Sea-Dog bow shackle is a simple, strong connection point for anywhere on the boat you need one. Cast from 316 stainless steel with a hand-threading screw pin, it shrugs off saltwater and takes load from more than one direction, which makes it a natural for anchor rodes and everyday rigging.
The Sea-Dog bow shackle gives you a simple, strong connection point anywhere you need one on the boat. It's cast from 316 stainless steel, the grade that holds up to saltwater without rusting or pitting, so you can leave it rigged season after season. The rounded bow shape spreads the load across a wider angle than a straight D-shackle, which makes it the right pick for anchor rodes and any spot where lines pull from more than one direction.
The screw pin threads in by hand and snugs down with a screwdriver or a marlinspike through the eye. That means you can connect and disconnect it out on the water without digging for tools. The 5/16 inch pin and 11/16 inch inside width handle light to medium rigging jobs. Think anchor chain to rode, snatch blocks, flag halyards, or securing gear on deck.
You get one shackle per package. On anything that matters, mouse the pin with a short piece of seizing wire or a zip tie through the eye so vibration can't walk it loose. It's cheap insurance against losing gear overboard.

Frequently asked questions
Why does 316 stainless steel matter on a shackle?
316 is the marine grade. It has molybdenum added, which helps it shrug off salt spray and submersion without the surface rust you get on cheaper plated hardware. For anything living on deck or near the water, it's the grade you want.
What's the difference between a bow shackle and a D-shackle?
The bow, or anchor, shackle has a rounded loop instead of a straight one. That wider curve lets it take load from several directions at once, which is why it's the standard choice for anchor rodes and bridle connections. A straight D-shackle is happier with an inline pull and doesn't like side loading.
How do I keep the screw pin from backing out?
Mouse it. Run a short piece of stainless seizing wire or even a zip tie through the pin eye and around the shackle body so vibration can't walk it loose. Takes a minute and saves you from losing gear overboard.
What size pin and opening does this shackle have?
The pin is 5/16 inch and the inside ring width is 11/16 inch. That's a good match for light to medium rigging and anchor work on small to mid-size boats.
