G70 5/16 Chain Hook Heavy Duty Clevis Grab Hook - Trailer Transport

In this review of the G70 5/16 Chain Hook, the bottom line is clear: this four-pack of forged clevis grab hooks is designed for anyone who needs reliable, non-slip connections for heavy-duty transport chains. The reviewer found the hooks best suited to utility trailers, flatbed and truck transport use because of their high Working Load Limit and zinc-plated finish. The review focuses on build quality, load capacity, and practical fit for 5/16 in grade 70 chain, assessing whether these hooks deliver the strength and compliance required for safe hauling.

Key Features

• Working Load Limit: Rated at 5,400 lbs WLL, the hook gives a predictable capacity for common trailer and transport chain tasks.
• Breaking Strength: With a 21,600 lbs breaking load, the hook provides a substantial safety margin for heavy-duty applications.
• Forged Alloy Steel: The hooks are forged from heavy duty alloy steel for durability under repeated tension and impact during loading and transport.
• Zinc-Plated Finish: A yellow chromate zinc-plating improves corrosion resistance and extends service life in outdoor and marine environments.
• Chain Compatibility: Specifically sized to fit 5/16 in Grade 70 transport chains, providing a secure, non-slip grab when properly attached.
• Regulatory Compliance: Each hook meets FMCSA and DOT requirements and is supplied with a guarantee for peace of mind on public roads.

Who It's For

This set is aimed at professional drivers, fleet operators, and serious DIYers who regularly secure heavy loads on utility trailers, flatbeds, trucks, or small cranes. The four-pack format suits shops that service multiple trailers or users who want spares for interchangeability.

Those who should look elsewhere include users needing hooks for fine rigging where smaller, lighter fittings are required or anyone whose chain is not Grade 70 or not 5/16 in, since the fit and rated performance depend on matching that chain size and grade.

Pros & Cons

Pros

• High WLL and breaking strength give a strong safety margin for transport tasks.
• Forged alloy steel construction feels robust and holds up under repeated use.
• Zinc-plating helps resist rust in outdoor and coastal environments.

Cons

• Designed specifically for 5/16 in Grade 70 chain, so it is not universal for all chain sizes.
• The finish may show wear over time under heavy abrasion despite plating.
