5/16ft Grade 100 Eye Self Locking Hook WLL 5700 lbs - Durable Lift

In this review the 5/16' Grade 100 Eye Self Locking Hook is evaluated for rigging and field repair use; it is aimed at tradespeople and rigging crews who need a compact, high-strength connector that reduces the chance of accidental release. The bottom line: this hook's defining advantage is its combination of a 5,700 lb working load limit and a self-locking latch that prevents the hook from catching or slipping, making it a dependable choice when paired with chain and alloy connecting links for onsite repairs and lifting tasks.

Key Features

• Working Load Limit: The 5,700 lb WLL gives clear guidance for safe loads and helps match the hook to appropriate chain and slings.
• Breaking Strength: A 22,800 lb breaking strength provides a wide margin between normal use and ultimate failure, adding confidence under heavy use.
• Material and Construction: Made from Grade 100 alloy steel and drop forged for durability and consistent performance in demanding environments.
• Self-Locking Latch: The locking latch reduces the chance of accidental detachment by preventing the hook from catching on the edge of a carrier bed or other contact points.
• Finished for Visibility: Painted blue finish helps with easy identification during inspections and resists corrosion in typical jobsite conditions.
• Standards Compliance: Meets strength and performance requirements of ASME B30.26 and is designed with a 4:1 safety factor for industrial use.

Who It's For

The hook is best for rigging professionals, maintenance crews, and contractors who need a compact, Grade 100 lifting connector for chain assemblies and emergency field repairs. It is particularly useful when a clear working load limit and a self-locking mechanism are priorities for safety and speed on site.

Those who should look elsewhere include users who need swivel hooks, very large capacity hooks, or hooks intended for non-industrial decorative use; rigging scenarios requiring specialized certifications beyond general ASME B30.26 compliance may also need different hardware.

Pros & Cons

Pros

• High strength-to-size ratio with a 5,700 lb WLL from Grade 100 alloy steel.
• Self-locking latch minimizes accidental detachment during handling and transport.
• Drop forged construction and painted finish support durability and easier inspections.

Cons

• Not suitable for operations that require a higher WLL than 5,700 lb or a different connection style.
• Painted finish may wear over time and require periodic inspection to ensure no hidden damage.
