The LD-388 carbon steel zinc hook bolt and eye bolt series provides versatile anchoring solutions for concrete embedment and masonry fastening applications. The product line includes multiple termination configurations to accommodate different loading requirements and attachment methods. The J-hook design features a bent J-shape termination ideal for securing cables, chains, and suspension wires. The U-hook configuration provides a U-shaped opening for supporting pipes, rods, and brackets. The O-ring eye bolt offers a closed-loop termination for lifting, rigging, and permanent attachment points. The L-bolt configuration provides a simple L-shaped embedment anchor for general-purpose fastening. Each configuration is manufactured from high-strength carbon steel and finished with yellow zinc chromate plating for reliable corrosion resistance.

The hook and eye terminations are produced using either precision forging or controlled bending processes, depending on the configuration and diameter. Forged eye bolts provide superior strength and are preferred for applications where the termination may be subjected to tension or lifting loads. Bent hook configurations offer economical production while maintaining adequate strength for typical anchoring applications. The threaded portion of each anchor uses standard metric coarse thread, ensuring compatibility with standard nuts, washers, and fixture hardware. The embedment portion of cast-in-place versions features a plain or deformed shank that grips the concrete matrix, while post-installed versions incorporate an expansion mechanism that engages the walls of a pre-drilled hole. The yellow zinc chromate plating provides a protective barrier against corrosion, making these anchors suitable for both indoor and sheltered outdoor applications.

Load considerations for hook and eye bolts depend on the configuration, diameter, embedment depth, and direction of loading. Cast-in-place embedment anchors achieve their full rated capacity when the concrete has reached its design strength and the embedment depth meets or exceeds the manufacturer’s minimum specification. Post-installed expansion versions achieve load capacity through friction and mechanical interlock within the drilled hole. J-hooks and U-hooks are primarily designed for axial pull-out loads and some lateral loads, while O-ring eye bolts can handle tension loads along the bolt axis. For applications involving angular loading or lifting, always consult the manufacturer’s rated angular capacity and use forged eye bolts specifically certified for lifting applications. Shank diameters range from M6 to M12, with overall lengths from 80mm to 250mm, covering a wide range of fixture and embedment requirements.

These hook and eye bolts are used across diverse construction, industrial, and infrastructure applications. Common installations include securing hanging fixtures and suspended equipment to concrete ceilings, attaching cables, chains, and ropes to concrete walls, mounting gate and fence hardware to concrete posts and walls, installing lifting and rigging anchor points in industrial facilities, fastening safety barriers and guardrail cables to concrete structures, and anchoring utility and mechanical equipment supports. The yellow zinc plating provides corrosion protection suitable for most indoor and sheltered outdoor environments, and custom plating options including galvanized and stainless steel finishes are available for more demanding environments. With CE and ISO 9001 certifications, the LD-388 series delivers consistent quality and performance for professional contractors, rigging specialists, and OEM manufacturers.
