The Grade 80 Eye Bolt with Key (EBK Type) solves the limitations of standard eye bolts by providing a safe, highly adjustable lifting point. It is the ideal solution for handling heavy molds, dies, and machinery that must be turned or flipped without the risk of the bolt unscrewing or bending.
The Grade 80 EBK Rotating Eye Bolt solves the limitations of standard eye bolts. Featuring a 360° swivel action, the eye automatically adjusts to the direction of the pull, preventing the bolt from unscrewing or bending during side loading. It is the ideal solution for lifting heavy molds, dies, and machinery that must be turned or flipped.
Insert the detachable Safety Key into the top of the unit. This engages the bolt mechanism, allowing you to torque it down securely.
Remove the key. This disengages the bolt from the eye, allowing the eye to rotate 360° freely around the bolt without unscrewing it.
The eye rotates freely to align with the load. This eliminates the dangerous "unscrewing" effect that occurs when standard eye bolts are subjected to side loads.
Manufactured from G80 Alloy Steel. Offers significantly higher Working Load Limits (WLL) than standard DIN 580 carbon steel eye bolts of the same thread size.
Perfect for 90° lifting and turning operations. The compact design and high side-load capacity make it essential for tool and die handling.
Designed with a 4:1 Safety Factor in all directions. Available in a wide range of Metric (M8 - M48) and UNC threads.

Types, Installation, Safety & Working Load Limits
An eye bolt is a mechanical fastener with a threaded shaft and a loop (eye) at one end. It is designed to be screwed into a structure or equipment to provide a secure lifting point or a tie-down point.
Eye bolts are critical components in rigging operations, allowing wire ropes, shackles, or cables to be attached to loads such as motors, containers, mold plates, and machinery for lifting, tensioning, or securing.
Choosing the correct pattern is crucial for safety. The two most common types are:
Features: Has a "shoulder" or "collar" between the eye and the threaded shank.
Use: Essential for angular lifting (lifting at an angle). The shoulder presses against the mating surface to support the bolt and prevent bending.
Features: No shoulder; the thread transitions directly to the eye.
Use: Designed strictly for vertical lifting only (in line with the bolt axis).
Features: Designed to be passed through a hole and secured with a nut on the other side.
Use: Typically used when there is no pre-tapped hole available, such as through a beam or a post.
Features: Has a coarse lag screw thread and a sharp point.
Use: Designed for screwing into wood or light duty anchors. Not for heavy machinery lifting.
For Machinery Eye Bolts (Shoulder Pattern), the shoulder must sit completely flush and firm against the mating surface. If there is a gap, the bolt is acting as a lever and is significantly weaker.
Lifting at an angle significantly reduces the Working Load Limit (WLL) of an eye bolt. Plain pattern eye bolts must NEVER be used for angular lifts.
When lifting at an angle, you must de-rate the bolt's capacity. Standard carbon steel eye bolts generally follow these guidelines:
| Direction of Pull | Angle (from Vertical) | Remaining Capacity (% of WLL) |
|---|---|---|
| Vertical Pull | 0° | 100% WLL |
| Slight Angle | 1° – 15° | 55% - 80% WLL (Check Mfr Specs) |
| Standard Angular Lift | 16° – 45° | 25% - 30% WLL |
| Extreme Angle | > 45° | NOT RECOMMENDED (Use Swivel Hoist Ring) |
*Note: Always consult the specific manufacturer's load chart, as values can vary by brand and material (e.g., DIN 580 vs. ASTM A489).
Grade 80 Sling Components are the long-established industry standard for chain slings and heavy lifting. Fully compliant with international lifting regulations and designed for durability.
Used to connect the sling to a crane or hoist hook.
End fittings for secure load attachment.
Essential hardware to join chains or fittings.
