                         Anchor Shackles Screw Pin Forged Alloy                     Chain Shackles Screw Pin High Tensile Forged Alloy

                Screw Pin Shackles can be used in any application where a         

                round pin shackle is used.  In addition, screw pin shackles 

                can be used for applications involving side-loading circumstances. 

                Reduced working load limits are required for side-loading applications. 

                While in service, do not allow the screw pin to be rotated by a live line,

                such as a choker  application.

                Bolt-Type Shackles can be used in any applications where round

                pin or screw pin shackles are used. In addition, they are recommended

                for permanent or long term installations and where the load may slide 

                on the shackle pin causing the pin to rotate.



                  Angle loads must 
             be applied in the 
             plane of the bow.

Side Loading Reduction Chart
 For Screw Pin and Bolt Type Shackles Only
 Angle of Side Load
 from Vertical In-Line of shackle
 Adjusted Working Load Limit
 0 In-Line *  100% of Rated Working Load Limit
 45 from In-Line *  70% of Rated Working Load Limit
 90 from In-Line *  50% of Rated Working Load Limit

                            *  In-Line load is applied perpendicular to pin.
                            DO NOT SIDE LOAD ROUND PIN SHACKLES


Never Exceed 120 included angle.
Use Bolt Type  and Screw Pin Shackles ONLY.


Shackles symmetrically                         loaded with two leg slings having a maximum included angle of 120 can be utilized to full Working Load Limit.
