1/4" 1/2 ton Screw Pin Carbon Anchor Shackle

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.
