An explosive bolt is a fastener that incorporates a pyrotechnic charge that can be initiated by an electrical command. Upon detonation, the bolt is destroyed, freeing the mated units from each other. They are often used in space applications to ensure separation between rocket stages, since they are lighter and more reliable than mechanical latches. A fastener is a hardware device that mechanically joins or affixes two or more objects together. ... Preparing C-4 explosive This article is concerned solely with chemical explosives. ...

Explosivebolts 84 have electrical leads 85 connected thereto for causing the explosivebolts to be severed and allow springs 86 to move halves 74 and 76 apart when desired to deploy subcaliber flechettes 22.
It is understood that leads 85 of explosivebolts 84 and leads 64 of explosivebolts 58 are connected to the electronics of the missile for severing the bolts to cause deployment of subcaliber missiles 22 at the appropriate time.
With the explosivebolts 84 released and nose sections 56 released, sections 50 pivot away from the missile due to high velocity windstream caught at the front of sections 50, pins 68 break, and fixture 72 moves outwardly to disperse subcaliber warheads 22.
Florence has the explosivebolts in the small box that Niomi brought back to her from the Explosive's Store.
The Space Shuttle, as I recall, is "bolted" to the launch gantry with a large handful of them, which are blown to release it from the external supports during launch.
"Explosivebolts" are very specific to each application- as noted, the "bolts" that jettison a fighter aircraft canopy can't be so powerful they throw shrapnel at the pilots.
