1/4″ Inch Aluminum Open End Blind Rivets

1/4″ Inch Aluminum Open End Blind Rivets are a common fastener used for structural connections.

Basic Parameters

Size: diameter of 1/4 inch (6.40mm)
Type: Open End, Blind Rivet
Material: usually rivet body for aluminum alloy, rivet mandrel for steel or stainless steel

Structure and Working Principle

The 1/4” inch aluminum open end blind rivet consists of two parts:

Rivet Body: a hollow aluminum tube that is inserted into the connector hole;
Rivet Mandrel: through the center of the rivet body with the head protruding.

During installation, the mandrel is pulled, expanding the rivet body outward and forming a “flap” to clamp the workpiece. The mandrel eventually breaks off, leaving the rivet body to hold the two pieces of material together.

Advantages of 1/4″ Inch Aluminum Open End Blind Rivets

Single-sided operation: suitable for blind-hole environments
Lightweight and corrosion-resistant: Aluminum has good corrosion resistance and is lightweight
Cost-effective: fast installation and simple tools

Application Scenarios of 1/4″ Inch Aluminum Open End Blind Rivets

Thin sheet metal connections (e.g. sheet metal, aluminum, steel)
Building assemblies, machine housings
Automobile manufacturing, trailers, ventilation systems
Typically used for low load connections, particularly suitable for locations where the backside is inaccessible

Cautions of 1/4″ Inch Aluminum Open End Blind Rivets

Not recommended for load-bearing structures
Should be used with suitable installation tools (hand riveters or pneumatic tools)
Aluminum blind rivets should avoid direct contact with stainless steel in electrochemical environments to prevent galvanic corrosion.
