Actek M33 x 3.50 x 58 mm Metric Safety Swivel Hoist Ring (46961) – 10,000 kg (22,045 lb) WLL

The Actek #46961 (AK46961) Metric Standard U-Bar Safety Swivel Hoist Ring is an precision-engineered alloy steel lifting point rated for a 10,000 kg (22,045 lb / 10 metric ton) Working Load Limit (WLL) with an M33 x 3.50 Metric mounting thread and 58 mm effective thread projection (dimension E). Built to rotate a full 360° and pivot 180° across its 38 mm diameter U-bar bail, this metric hoist ring aligns smoothly with the line of pull and holds 100% of its rated WLL at any lifting angle from 0° to 90°.

Application & Installation Guidelines

Its compact Standard U-Bar bail provides 138 mm of interior vertical clearance (dimension B) and 271 mm of overall height (dimension F), keeping profile height low while easily accepting standard rigging hooks and alloy shackles. Unlike conventional rigid shoulder eye bolts—which suffer severe capacity derating and bending stress under side loads—the Actek #46961 swivel hoist ring pivots and swivels freely so the bail aligns with the sling leg. Every unit is manufactured from certified heat-treated alloy steel, 100% magnetic particle inspected, and individually proof-load tested to 200% of Working Load Limit with a permanent serial number stamped on the body for full inspection traceability.

Mounting & Torque Requirements: Always seat the 94 mm bushing flange (dimension I) flush against a flat, machined mounting surface so the U-bar can rotate 360° and pivot 180° without striking adjacent walls or corners. Torque the mounting screw to the recommended 637 Nm and re-check torque periodically during extended service. To achieve full rated capacity in a tapped blind hole, the parent material should have a minimum tensile strength of 80,000 PSI; for softer steels, aluminum, or cast iron, use a through-hole installation secured with a matching high-strength nut and flat washer on the underside. When lifting with multiple hoist rings at an angle, remember that sling leg tension increases as the horizontal sling angle A decreases (Load per Ring = Total Weight / [Number of Rings × sin A]); never exceed the 10,000 kg (22,045 lbs / 10 t) rating per ring or apply shock loads.

Safety

Misuse of rigging and safety gear can result in serious injury including loss of life. At no time should rigging or safety gear be used beyond its certified Working Load Limit (WLL). All hoist rings and lifting hardware must be thoroughly inspected before every lift by a competent person, properly torqued, and kept free to pivot and swivel without obstruction. Worn, damaged, or shock-loaded rigging gear must never be used. Slings Unlimited disclaims liability for any misuse or incorrect product selection by our customers.
