1/2" Grade 70 Clevis Grab Hook — High-Capacity Transport Chain Hook at 6,600 lbs WLL

The 1/2" Grade 70 clevis grab hook is the heaviest transport-grade G70 hook in the standard chain size lineup. At 6,600 lbs WLL with a 4:1 design factor (26,400 lbs break strength), it's the right choice for heavy equipment, large commercial vehicles, and loads that demand maximum capacity within the Grade 70 transport chain system.

Heat-treated alloy steel, "G70" stamped for DOT/FMCSA identification, and precision-built for 1/2" Grade 70 chain. If your securement design calls for 1/2" chain, this hook is its correct end fitting.

When 1/2" Grade 70 Is the Right Choice

The step from 3/8" to 1/2" G70 chain nearly doubles the cross-sectional mass of each link, increasing WLL from the 3/8" hook's 6,600 lbs to — at the same G70 rating — a heavier and more robust assembly overall. This size is most often specified for heavy construction equipment transport, large commercial flatbed loads, and applications where aggregate WLL requirements push beyond what a practical number of 3/8" chains can achieve.

Note: Grade 70 is a cargo securement standard, NOT an overhead lifting standard. These hooks are for DOT/FMCSA-regulated cargo securement only — never use transport chain or hooks for overhead lifting operations.

Frequently Asked Questions

What is the WLL on a 1/2" Grade 70 grab hook?

6,600 lbs working load limit with a 4:1 design factor — 26,400 lbs break strength. This is the same WLL figure as the 3/8" G70 hook due to how chain grade and size interact in the G70 standard. Note that the 1/2" hook is a larger, heavier hook and is designed for 1/2" chain — do not attempt to use it on 3/8" chain.

Can Grade 70 hooks be used for overhead lifting?

No. Grade 70 is a cargo transport standard, not an overhead lifting standard. Overhead lifting applications require Grade 80 or Grade 100 rated rigging — different alloys, different design standards, different inspection requirements. Using transport chain or transport hooks for overhead lifting is unsafe and violates applicable lifting standards.

How does 1/2" G70 compare to 3/8" G70?

Both are Grade 70 transport rated with 6,600 lbs WLL per hook — the same rating. The 1/2" hardware is physically larger, heavier, and built for 1/2" chain link geometry. The choice between them is driven by the chain size in your assembly, which is driven by your aggregate securement requirements and trailer configuration — not by the WLL of the hook alone.
