PIN TYPES AND APPLICATIONS ROUND PIN SHACKLES SCREW PIN SHACKLES Round Pin Shackles can be used in tie down, towing, suspension or lifting applications where the load is strictly applied in-line. BOLT-TYPE SHACKLES Screw Pin Shackles can be used in any application where a round pin shackle is used including applications involving side-loading circumstances where reduced working load limits are required. 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 application where a 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.
Replacement Shackle Pins Can a shackle pin be replaced? Providing the pin and the body do not come from different manufacturers and that the correct type of shackle pin is fitted and that the pin meets the fit requirements specified in EN 13889 - or the standard to which it was made- then there is no reason to reject a shackle because it has a new pin
