Common questions about eye bolts · din 444
Is a DIN 444 eye bolt a rated lifting eye?
A catalog eye bolt is not automatically a rated lifting accessory. If lifting is required, specify a qualified lifting product and its applicable load rating separately.
Can I request a size or material outside this listing?
Yes. Send the required dimensions and exact material grade for review. A quotation is needed to confirm feasibility, price and lead time.
