Made in USA - The sizing description of a screw pin shackle is based upon the measured diameter of the shackle’s body, often called the bail, which is the curved top section of the shackle. The threaded shackle pin itself will have a slightly larger diameter than the shackle body. The shackle pin diameter is not the measured dimension used to describe the size of the shackle.
The shackle body will be stamped with the Working Load Limit (WLL), which is represented in Tons or fractions of a Ton, depending upon the shackle size.
To see the pin diameter of this shackle please view the Technical Specs on this page. This screw pin shackle features a Hot Dip Galvanized coating ideal for Marine and Exterior applications.
Size, working load limit, and trademark are permanently marked on all shackles. All shackles and pins are heat treated. Loads are based on a design factor of 6 to 1, except (1-3/8" diameter) which is 5 to 1. When tested all shackles are pulled at a uniform rate of speed in a direct tension.
- Meets or exceeds all requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements
- Shackles Meet Performance Requirements of Federal Specifications RRC-271F Type IVA Grade A
