How Frangible Nuts Work
The frangible nut is an explosively separated nut design used to sever mechanical connections, where the bolt or stud will remain intact while the nut itself is split into two or more pieces.
The frangible nut contains machined features that provide break plane location(s) (webs) to control the separation, fragmentation and the design’s breaking strength. Explosive booster assemblies are strategically located within the nut assembly, and upon actuation will separate the nut at the pre-determined break plane(s). The booster(s) are functioned simultaneously to ensure that the nut splits uniformly, allowing for a clean separation of the joined assemblies.
