Actek Forged Alloy Swivel Hoist Rings — Inch & Metric Selection Guide

Actek Manufacturing & Engineering forged alloy steel safety swivel hoist rings rotate 360° and pivot 180° under load, maintaining 100% of their rated Working Load Limit at any lifting angle with a 5:1 design factor and 200% proof-load certification.

200% Proof-Load Tested with Serial Traceability

Every Actek hoist ring is individually proof-load tested to 200% of rated Working Load Limit, magnetic-particle inspected, and stamped with a unique serial number.

Inch (UNC) & Metric (M6–M48) Thread Sizes

Stocked in Standard U-Bar, Long U-Bar, and Side-Pull configurations from 1/4"-20 (550 lbs WLL) and M6 up to heavy-duty 1"-8 (10,000 lbs) and M48 models.

5:1 Design Factor per ASME B30.26

Meets or exceeds ASME B30.26 and MIL-STD-209 requirements with black oxide corrosion protection and replaceable alloy hex socket cap screws.

Frequently Asked Questions

Are Actek swivel hoist rings individually proof-load tested?
Yes. Every Actek safety swivel hoist ring is individually proof-tested to 200% of its rated Working Load Limit and engraved with an individual serial number for certification traceability.
Do Actek hoist rings lose capacity when loaded at a 45° or 60° sling angle?
No. Unlike standard eye bolts, Actek swivel hoist rings rotate 360° and pivot 180° so the bail aligns directly with the line of pull, maintaining 100% of rated Working Load Limit at any sling angle.
How tight should the bolt on an Actek swivel hoist ring be torqued?
Tighten the alloy bolt to the exact foot-pound (ft-lbs) or Newton-meter (Nm) installation torque stamped directly on the hoist ring body, ensuring the bushing flange seats flush against the workpiece.
What is the difference between a Standard U-Bar and a Long U-Bar Actek hoist ring?
Long U-Bar models have an extended bail clearance height to accommodate larger crane hooks, foundry hooks, or recessed mounting holes where a standard bail would bind.
Can I replace the bolt in an Actek hoist ring with a hardware-store bolt?
Never use standard commercial bolts. Always use genuine Actek certified alloy steel replacement shoulder bolts with matching thread projection and magnetic-particle certification.
