Application Information
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.

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. Shackles symmetrically loaded with two leg slings having a maximum included angle of 120 can be utilized to full Working Load Limit.
Use Bolt Type and Screw Pin Shackles ONLY.
