4,700 lbs per hook with a 4:1 design factor (18,800 lbs break strength). This is the correct rating for 5/16" Grade 70 hooks — smaller in cross-section than 3/8" hooks, which are rated at 6,600 lbs WLL. Always verify hook WLL matches chain WLL in any assembly.

Yes, when used with 5/16" Grade 70 transport chain on regulated commercial vehicles. The "G70" stamp is the DOT/FMCSA-recognized identification mark. Always verify your aggregate WLL meets the requirements of FMCSA 49 CFR Part 393 for the load being secured.

The shallow throat opening on a grab hook is sized precisely for one chain link. When the assembly is under tension, the chain link is pulled tight into the throat, which physically prevents it from moving. Unlike a slip hook — which has a wide throat allowing the chain to pass through — a grab hook captures the link permanently until you manually remove it by releasing tension and sliding the link out.

If you're building custom-length assemblies or replacing hooks only on existing chains, these grab hooks are exactly what you need. Check our chain collection for complete assembly options.
