Abstract:

A fastening system having differentiable components includes a first fuse pin with a first mating figure and being configured to shear upon the application of a first predetermined load and a first receiver with a second mating feature. The first and second mating features correspond and permit the insertion of the first fuse pin into the first receiver to selectively connect components. The system may include a second fuse pin having a third mating feature and being configured to shear upon the application of a second predetermined load, which may differ from the first predetermined load. The second fuse pin having a third mating feature that prevents the insertion of the second fuse pin into the first receiver. The first fuse pin may be configured to connect together components of a first aircraft and the second fuse pin may be configured to connect together components of a different aircraft.
