We run every single one through 100% Magnaflux crack detection before it leaves—that's not optional, it's standdard, and it catches micro-fractures you'd never see with the naked eye.
The quench and temper cycle gives these hooks a 4:1 safety factor, so your proof load hits 2.5 times WLL; most buyers don't realize teh fatigue rating at 1.5x for 20,000 cycles actually matters more than raw tensile in high-cycle environments like automated lines or offshore cranes where you're not swapping gear every week.
You'll want the powder coating if you're working outdoors or in wet conditions—red, blue, or black (roughly 3-5 days for custom colors), but honestly the coating is more about rust prevention than looks. 16mm to 32mm covers most chain sizes, and we typically stock 1.2T through 31.5T WLL ranges (check lead time on anything above 20T).
It's not great for stainles applicaion or food-grade environments since the alloy steel will pit eventually. The cast latch is a weak point compared to forged options, so keep it below 80% of WLL for repeated blind lifts.
Also, we usually get 100-piece MOQ out the door in 20 days or so—but confirm lead time if you need traceability codes stamped deeper than 0.3mm, because that can add a week.
MOQ is 100 pieces. For custom orders, you can choose your preferred color or add your own markings. Just let us know the details and we'll handle the rest.
Yes, we include CE and ISO certifications with every batch. We also test every hook with 100% Magnaflux crack detection, so you get full traceability and quality proof.
It means the hook is designed to handle up to 4.8 tons before breaking, with a proof load of 3 tons. That's a solid margin for safe lifting.
Absolutely. The powder coating resists corrosion and wear well, and you can pick from red, blue, black, or other colors. It holds up fine in most industrial settings.
Typically, we ship within 15 to 20 working days after order confirmation. If you need a faster turnaround, just ask—we can often adjust the schedule.
