The HA Offshore Swivel Hoist Ring (UNC Thread) from William Hackett is an expertly engineered bolt-on load attachment that has been specifically designed for lifting and handling loads in extreme, corrosive environments.

Available in thread sizes 1/2" to 2-1/2" (2200lbs - 44550lbs), all load bearing components have been manufactured from allow steel (quenched & tempered) with the body and bail, and L7 bolts featuring a a maximum hardness range of 35-40 HRC and 32 HRC, respectively.

Capable of rotating 360° around the bolt axis, as well as pivot 180°, these hoist rings orientate to the appropriate angle of lift, reducing the risk of damage.

Boasting an operational temperature range of -40°C to +200°C without reduction in working load limit, these hoist rings are suitable for both top and side mounting applications, maintaining full working load limits even when pulled at 90°.

With a safety factor of 4:1. these swivel rings have been proof tested to 2.5 times the stated WLL, and are fatigue rated to 20,000 cycles at 1.5 times the WLL. Additionally, all load rated parts have been subject to 100% magnaflux crack detection following heat treatment.
