The frangible nut is a component used in many industries, but most commonly by NASA [citation needed], to sever mechanical connections. It is, by definition, an explosively-splittable nut. The bolt remains intact while the nut itself is split into two or more parts. [1]

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 has been modified to incorpo-rate a crossover assembly which pyrotechnically “links” the two booster cartridges/detonators in each frangible nut, resulting in detonation of both sides within 50 microseconds or less, versus a National Aeronautics and Space Administration

The museum displays a Shuttle solid rocket booster hold-down bolt and frangible nut. Four such bolts held down attached each SRB to the mobile launcher platform, each attaching to one of the hold-down posts on the SRB's aft skirt.

The separation nut is a pyrotechnic device designed to perform two functions – keep a pre-loaded assembly of two sets intact and then, upon an electrical signal, releasing the assembly.

From debris-free frangible joint assemblies, to high preload separation bolts, to ultra low shock NEA® Hold Down Release Mechanisms and resettable TiNi™ ejectors, EBAD offers diverse technologies to help customers solve the most challenging separation events.

The 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.

A frangible nut is intentionally created to split into two halves, doing so when two pyrotechnic devices break the nut thereby releasing the objects being held together. NASA’s Space Shuttle Rocket Boosters are a great example of this device in action.

The single piece Frangible Nut is uniquely machined from Inconel to have a pre-defined separation plane. Four precision-machined webs hold the two halves of the Frangible Nut together.
