CM Carbon Screw Pin Anchor Shackles

Screw Pin Shackles allow for quick and easy removal of the screw pin, which makes this style ideal for applications where the shackle is removed frequently. While the threaded pin can resist axial forces, it should not be cyclically loaded and is unreliable and vulnerable to backing out in applications where the pin is subjected to a torque or twisting action. Recommended for overhead lifting, screw pin shackles are available in capacities up to 43 tons. Screw pins should be moused in some applications. Benefits & Features Manufactured from technically advanced domestic (U.S.A.) micro alloy steel with optimal hardness for strength and ductility.
