Why use 304 stainless for eye nuts?
304 is the workhorse austenitic stainless, giving strong corrosion resistance for outdoor and freshwater use. As a Style A eye nut it threads onto a stud or bolt to create a compact, general-purpose lifting point for straight, in-line loads. Seat it squarely on a flat surface or hardened washer, engage full threads (at least one bolt diameter in steel), and align the eye with the pull. Pair it with 304 or 18-8 stainless studs and hardware. For coastal or saltwater exposure, step up to 316. Avoid side loading unless derated, and confirm the rated capacity before each lift.
