A pyrotechnic fastener (also called an explosive bolt, or pyro, within context) is a fastener, usually a nut or bolt, that incorporates a pyrotechnic charge that can be initiated remotely. One or more explosive charges embedded within the bolt are typically activated by an electric current, and the charge breaks the bolt into two or more pieces. The bolt is typically scored around its circumference at the point(s) where the severance should occur. Such bolts are often used in space applications to ensure separation between rocket stages, because they are lighter and much more reliable than mechanical latches.

- 分離ボルト（ぶんりボルト、英語：explosive bolt）とは火工品の一種で別名爆裂ボルト、爆砕ボルト、爆発ボルトとも呼ばれる。 ボルトの中を中空にしてそこに爆薬を充填し、電気雷管を埋め込んだ物である。起爆すると切断面から断裂し真っ二つに折れることで部品の固定を解く。 周囲を傷つけないように破片の飛び散らないタイプもある。爆轟型の他に燃焼型もあるが海外では動作が確実な爆轟型が大半であり、燃焼型は主に爆薬を用いることが法規制上困難な場合などに用いられる。 (ja)
- Пироболт (разрывной болт) — пиротехнический энергодатчик в виде корпуса с запрессованным пиротехническим составом и пиротехническим воспламенителем. Предназначен для соединения и последующего автоматического разъединения различных узлов. Разъединение происходит путем расплавления паянных швов. По классификации ГРАУ получают индекс с префиксом 9Х… — заряды твердотопливных ракетных двигателей, трассеров, разрывные заряды. (ru)
- 爆炸螺栓是一種爆裂性緊固件。 將螺栓挖空就會充滿爆裂性，並用雷管包埋。引爆時，零件會從切割的表面裂開並裂成兩半而無法擰緊。 還有一種不會散落碎屑，以免造成周遭環境污染的爆炸螺栓。除能爆炸類的螺栓外，還有燃燒類的螺栓，但大多數爆炸類螺栓在美國大致上都可允許使用，燃燒類的螺栓主要用於法律規定難以使用炸藥的場合下。 為了安全和可靠性，在航空技術中通常使用和，而不是傳統的雷管。 最近的發展已使用脈衝激光二極管通過光纖電纜引爆，發射主炸藥然後爆炸。 類似於菸火緊固件。它們用於產生大量氣體，例如用於渦輪泵，使氣球（尤其是安全氣囊）膨脹，以噴射降落傘和類似用途。 (zh)

- Un bullone esplosivo è un dispositivo per fissare e all'occorrenza rilasciare all'istante due parti meccaniche. In pratica, si tratta di un bullone con del materiale esplosivo incorporato. Questa carica viene fatta esplodere da remoto, solitamente con un impulso elettrico, e ha la funzione di distruggere il bullone stesso. Distrutto quest'ultimo, infatti, le due parti precedentemente fissate tornano libere di separarsi. Più recentemente, è possibile utilizzare diodi laser per far esplodere detonatori attraverso fibre ottiche. (it)

The bolt is typically scored around its circumference at the point(s) where the severance should occur. Such bolts are often used in space applications to ensure separation between rocket stages, because they are lighter and much more reliable than mechanical latches. In applications that require safety, precision and reliability, such as the aerospace industry, pyrotechnic fasteners are triggered using exploding bridgewire detonators, which were themselves later succeeded by slapper detonators. Classical blasting caps are generally avoided for such usage. More recent developments have used pulsed laser diodes to detonate initiators through fiber-optic cables, which subsequently fire the main charge. Gas generators are similar to pyrotechnic fasteners. They are used to generate large amounts of gas, as for turbopumps, to inflate balloons, especially airbags, to eject parachutes and similar applications. (en)

Distrutto quest'ultimo, infatti, le due parti precedentemente fissate tornano libere di separarsi. Questo meccanismo di fissaggio e rilascio rapido è usato spesso in astronautica, ad esempio nella separazione degli stadi dei razzi vettori, in quanto più leggero e molto più affidabile dei fermi meccanici. Anche in aviazione trova largo impiego, per esempio per far saltare il tettuccio della carlinga in caso di emergenza. Più recentemente, è possibile utilizzare diodi laser per far esplodere detonatori attraverso fibre ottiche. (it)
