Grade 80 clevis self-locking safety hook

Key Features:

• Clevis Mount Design: U-shaped clevis end with a pin hole allows secure attachment to shackles, D-rings, or master links—ideal for pivoting or swiveling under load.
• Self-Locking Safety Latch: Spring-loaded mechanism automatically secures the hook throat upon engagement, preventing accidental disengagement due to vibration or shock—fully compliant with OSHA and ASME B30.10.
• Features a gracefully curved shank and smooth eye that promote optimal load alignment and reduce wear on slings and chains.
• Grade 80 Alloy Steel Construction: Heat-treated to meet ASTM A342 and EN 1677 standards, with a minimum tensile strength of 800 N/mm² (116,000 psi) and a 4:1 safety factor—certified for overhead lifting.
• Permanent Markings: Clearly stamped with Working Load Limit (WLL), size, Grade 80 designation, manufacturer ID, and CE mark for full traceability and regulatory compliance.
• High-Visibility Finish: Typically coated in red or yellow powder paint for corrosion resistance and easy on-site identification.

Common Applications:

• Overhead crane and hoist systems
• Multi-leg chain or synthetic sling assemblies in oil & gas, mining, and steel fabrication
• Recovery, transport, and heavy equipment lifting
• Marine and offshore rigging where secure, articulated connections are essential

Safety Recommendations:

• Use only with other Grade 80 components to maintain system integrity.
• Never exceed the marked WLL.
• Inspect before each use—retire immediately if the latch is damaged, stiff, or fails to close securely.
• Intended for in-line (axial) lifting only—side loading is strictly prohibited.
