Twist Shackles
Hayn Twist Shackles are Type 316 stainless steel shackles with a twisted body that offsets the pin axis from the bow axis, allowing connection to fittings where a standard D or bow shackle would create misalignment, available in three pin configurations across nine sizes with minimum breaking loads from 1,320 lbs through 24,200 lbs.
Twist Shackles
The twisted body geometry rotates the pin axis relative to the bow so the shackle can connect hardware sitting at an angle to the load direction without introducing side-loading or misalignment into the assembly — the same functional advantage as the Long Twist Shackle in a more compact body form. Standard screw pin covers everyday connections; socket head pin offers a cleaner profile where tool access is limited; and shake proof retained pin adds positive locking for high-vibration or offshore applications. Available across pin sizes from 5/32" through 3/4" with the full standard screw pin and socket head ranges running nine sizes, and shake proof available from 3/16" through 5/8" body diameter.
