This type 316 stainless steel twist shackle with screw pin is commonly used for attaching the jib halyard block to the mast, or the jib halyard to the sail, to reduce twist on the luff and allow the sail to set better. A twist shackle is usually somewhat longer than the average, and features a 90° twist so the top of the loop is perpendicular to the pin.
