Definition
A rivet designed to be installed and set from one side of a structure only, used where the back side of the work is inaccessible. The rivet is inserted into a hole, and a built-in mechanism (typically a pull stem or an explosive charge) expands the far end to form the bucked head without anyone needing to reach behind the material.
Plain English
A rivet you can install when you can only reach one side of the metal. A small mechanism inside the rivet does the work of forming the back side for you.
Context Anchor
Seen in aircraft sheet-metal repair, inspection panels, fairings, and other places where the back side of the structure is hard or impossible to reach.
Derivation
Called 'blind' because the installer cannot see the far side of the work — the side where the rivet's tail forms is hidden, or 'blind,' to the technician.
Why Pilots Care
Allows structural repairs without major disassembly, preserving airframe strength in areas that would otherwise be difficult or impossible to reach.
Analogy
Works like the pop rivets used to fix a metal shed or gutter where you cannot get behind the material.
Intuition Check
Blind does not mean the rivet is used without care or visibility. Here, blind means the back side of the material is not accessible during installation.
Example Sentence 1
The mechanic used blind rivets to close up the wingtip skin because the inside of the structure was sealed off.
Example Sentence 2
Several blind rivets were replaced along the fuselage skin during the pre-purchase inspection.
