When you need high-quality boat chains and shackles for your marine applications, you must ensure you purchase from a reputable boat parts supplier. At Sardine Marine, we are the trusted online shop for all AISI marine-grade 316 stainless steel shackles and chains for sale. Let us help with all of your boating, sailing, anchoring, and rigging needs.
Boat shackles are primarily used to link the chain to the anchor, but there are other marine applications. You may also need mooring shackles that are responsible for securing the boat. Whatever application you choose, your marine shackles must be built to handle harsh saltwater and freshwater environments, which is why we use 316 marine-grade stainless steel. You can choose from our vast selection of rigging shackles and chain shackles in various sizes, shapes, and purposes.
To start, you must determine if you are looking for bow shackles, otherwise known as anchor shackles, or D-ring shackles, otherwise known as chain shackles, as the shape between the two varies. You will also need to look at the pin-type because this can differ. Finally, examine the grade ratings and load ratings to ensure it fits with your application and the size of your boat.
The chain shackle is known as a D shackle because of the bow that is much narrower compared to the anchor shackle. These shackles are made for in-line tension, so you should never side-load them. If you do, expect to get bending or twisting of the shackle bow. Additionally, the center load line will always need to line up with the center of the shackle.
The screw pin shackle contains a threaded pin for a quick connection or disconnect. These aren’t recommended for long-term or permanent installations but do allow for side-loading. Additionally, bow shackles can be used for side-loading thanks to the O-shape. You can also use an anchor shackle for side pulling.
Snap shackles are different than the other types because they feature a captive pin. While these are still powerful and considered heavy-duty, you can use them quickly, making them perfect in lifting and rigging applications.
Heavy-duty jaw swivel snap shackles are made for use with jib and spinnaker halyard ends, along with additional rigging applications. With the swivel snap shackle, you get a removable clevis pin that increases the working load limit.
With a headboard shackle, you gain a captive pin along with self-locking features, so the pin doesn’t back out. Because it isn’t removable, it won’t fall out once it is opened. Additionally, a twist shackle usually is larger than the standard boat shackle, with a 90-degree twist to make the top perpendicular with the pin.
Along with our yacht shackles and clevis shackles, you can find various boat and anchor chains on our website. We supply everything you need for your rigging and lifting marine applications. If you don’t see what you need, give us a call today!
