What is explosive bolts?

Explosive bolts are mechanical fasteners that are designed to be remotely detonated to break apart and release a component or structure. They are commonly used in aerospace and automotive applications where a swift and precise separation is required.

Explosive bolts are typically made up of an explosive charge enclosed in a metal housing, which is attached to a bolt or pin. When the explosive charge is detonated, it creates a high-pressure gas that rapidly expands and shears off the bolt or pin, causing the components to separate.

These bolts are used in critical systems such as spacecraft separation mechanisms, aircraft ejection seats, and automotive airbag deployment systems. They provide a reliable and quick way to release components in emergency situations or during deployments.

Explosive bolts are carefully engineered to ensure safety and reliability, with measures in place to prevent accidental detonation. They are also designed to withstand harsh environmental conditions, vibration, and shock loads.
