When to choose Style B over Style A
Style B eye nuts have a heavier head and bell than Style A, which raises the lifting capacity for the same thread diameter. So when your load exceeds what a compact Style A eye nut can carry but you want to keep the same stud or bolt size, Style B is the answer. It threads onto a stud or bolt for straight, in-line loading, just like Style A. For even heavier, rugged service, Style D uses a larger section still. Seat the eye nut 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. Avoid side loading unless derated, and choose the material for the environment.
