Screw Pin—The most common shackle pin type. Although the pin easily connects and disconnects, it can come unscrewed or wear down over time, so it's best for temporary use.

Flush Screw Pin—The ends of the pin sit flush with the shackle, so they won’t snag or catch on anything that might loosen the shackle.

Captive-Locking-Screw Pin—The pin on these shackles won’t fall out or get lost. Even when unscrewed, an inner lip on the shackle ear keeps the pin from sliding all the way out. Indentations in the shackle body hold the head of the pin in place once fastened to secure it from vibration and movement.
