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.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eYou 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e316 stainless steel cast construction resists saltwater corrosion and pitting through years of exposed service\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch screw pin threads in by hand and snugs down with a screwdriver or a marlinspike through the eye\u003c\/li\u003e\n  \u003cli\u003e11\/16 inch inside width fits anchor chain, rode, and light to medium rigging hardware\u003c\/li\u003e\n  \u003cli\u003eRounded bow shape spreads multi-directional loads better than a straight D-shackle\u003c\/li\u003e\n  \u003cli\u003eSold as a single shackle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sea-Dog reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhy does 316 stainless steel matter on a shackle?\u003c\/summary\u003e\n    \u003cp\u003e316 is the marine grade.
