Don't expect these eye hooks to handle every extreme load situation—bearing capasity tops out at 1650kg on largest M16, so for heavy marine rigging beyond that you'll need a different fastening system, but for typical docking, rigging, or household hanging work they hold up well with a polished 304 or 316 stainlss steel finish that resists corrosion in saltwater or humid indoor settings.

We've seen buyers use them for everything from boat cleat attachments to securing garage shelves, and the D-shape design actually distributes stress better than round eye hooks in most pull directions—roughly 90kg on the smallest M4 size up to 1650kg on M16 (check your specific load requirement).

Suface treatment is polished, not matte, so they'll look clean on exposed hardware like kitchen pulls or bathroom towel racks, though the 316 grade is better for coastal environments than 304 (we usually have both in stock, but confirm lead time).

MOQ sits at 1000 pieces per size, lead time runs about 30-40 days after deposit, and we pack them inner bag plus carton—ISO 9001 production standard applies across all runs (COA provided with each batch if you request it).

One thing most buyers don't think to ask: the internal eye diameter varies slightly between M4 and M16 sizes, so if you're threading through rope or cable, double-check the hole clearance on your specific model—our company can send the exact drawing before you order if needed.

Basically, if you need stamped stainless eye hooks in M4-M16 with a polished finish and 1000-piece minimum, we've got them; just specify 304 or 316 when you place the order.
316 has more molybdenum, so it's better for saltwater marine environments. 304 works fine for general industrial or household use. We can supply either, just specify when ordering.
Yes, we operate under ISO 9001 standards and can supply material test reports for Stainless Steel 304 or 316 upon request. Just let us know what you need when you place the order.
The MOQ of 1000 pieces applies per order, but we can mix sizes as long as the total hits 1000. So you could order 500 M6 and 500 M10, for example.
We pack them in inner bags first, then into cartons. This keeps the polished silver finish scratch-free during transit. For larger volumes, we can also customize packaging if you need.
Our standard sizes run from M4 to M16, but if you need a different thread size or a custom D-shape design, send us your specs. We can adjust the tooling for custom stamping, though lead time may increase slightly.
