Eye bolts and eye nuts both provide an eye-shaped attachment point, but they connect differently. An eye bolt has a threaded shank that enters a tapped hole or threaded component. An eye nut has an internal thread and is fitted onto a matching stud or bolt.
The connection arrangement is the practical difference that guides most product enquiries.
When an eye bolt is used
Choose an eye bolt when the receiving component has a compatible threaded hole or when the fastener itself needs to pass into the assembly. Specify the thread and required shank length, as well as the intended use.
When an eye nut is used
Choose an eye nut when a compatible stud, bolt or threaded rod is already part of the assembly. The internal thread must match correctly, and the connected member needs to be suitable for the requirement.
Common selection questions
Buyers should confirm thread compatibility, contact surfaces, material, environment, load direction and whether the product is for lifting or securing. Product geometry and installation space may also determine which configuration is practical.
Avoid visual substitution
An eye nut and eye bolt may look interchangeable in a photograph, but the assembly and load path are different. Share a drawing, photo of the connection and dimensions when requesting a quote. Stainless applications may call for SS eye nuts or SS eye bolts.
