William Hackett Standard Length UNC Swivel Hoist Ring

The HA swivel hoist ring (UNC) is a reliable bolt-on load attachment designed specifically for loads with tapped holes. It offers impressive flexibility, rotating 360° around the bolt axis and pivoting 180°, which allows it to be positioned at the optimal angle for lifting and reduces the potential for damage. This hoist ring is versatile, accommodating both top and side mounting, and maintains its full working load limit even when pulled at a 90° angle.

Key Features

• WLL Range: 2200 lbs to 49500 lbs
• Proof Load Test: 2.5 x WLL
• Safety Factor: 4 : 1
• Temp Range: -40°C to +200°C
• Rotation: 360°
• Pivot: 180°

Additional Features

• Standards: Designed and manufactured in accordance with EN1677-1 and ASME B30.26.
• Product sizes: Available in sizes 1/2" to 2-1/2" and with working load limits from 2200 lbs to 49500 lbs.
• Product markings: Forged bail marked with manufacturer name "Hackett" and batch number for product material traceability. Body marked with recommended torque rating and working load limits in lbs (based on 4 : 1 and 5 : 1 safety factors). Bolt marked with UNC size, material grade, "HA" branding, and batch number for bolt material traceability.
• Temperature: Operational temperature range of - 40°C to + 200°C without reduction in working load limit.
• Material: Alloy steel.
• Bolt Grade: 10.9.
• Testing: Load rated parts are subject to 100% magnaflux crack detection following heat treatment. HA swivel hoist rings are proof tested to 2.5 times working load limit, and fatigue rated to 20,000 cycles at 1.5 times working load limit.
