We’re pretty careful about the materials we use to make our High Tensile Lifting Eye Nuts—it helps make sure they’re strong and work like they should.
We only get steel—whether it’s stainless, high-tensile, or carbon—from suppliers that follow standards like ISO 9001. Before we use it, we test the steel to see how much weight it can handle. Emphasis on the test requirement statement: In the load-bearing test, the standard nut should be able to bear a weight of 500 kg while maintaining structural integrity without any damage such as bending and breaking.
We also check the steel for flaws—cracks, rust, or uneven spots—since those can make the nut weaker. If a batch doesn’t pass, we send it back and find another supplier.
That’s how we make sure every High-Tensile Lifting eye nut starts with good material, so it ends up lasting.
We test every High Tensile Lifting Eye Nut carefully before it goes out to make sure it’s good to go.
First, we check the dimensional parameters (such as thread type, ring size, and overall length) to ensure they match the order requirements (for example, M16 thread with a 50 mm ring).
Then we test its strength: we hang a weight that’s 20% heavier than what the nut is rated for and leave it for half an hour to see if it bends or cracks.
We also test how well it screws on—we try it on a standard bolt to make sure it turns smoothly without damaging the threads.
For zinc-plated nuts, we also check that the coating looks even and doesn’t scratch too easily.
Only the nuts that pass all these checks get shipped—we don’t send out anything that doesn’t meet the standards.
