Black Tri-Fold Blind Rivets for Thin and Lightweight Materials
These blind rivets combine 304 stainless steel construction with a black electrophoretic coating. During installation, the rivet body forms three folding legs that create a wider bearing area on the blind side of thin sheet metal, fiberglass, plastic and composite materials.
Four Reasons to Choose This Rivet
304 Stainless Steel Construction
The 304 stainless steel base material is suitable for many general industrial, indoor, outdoor and moisture-prone applications.
Black Electrophoretic Coating
The black E-coat provides a consistent dark appearance and an additional protective surface layer over the stainless steel base material.
Tri-Fold Support for Thin Materials
The three folding legs create a broader blind-side contact area that helps distribute clamping load across thin and lightweight materials.
One-Sided Installation
Install the rivet entirely from the accessible side when the rear of the assembly cannot be reached.
Why the Black E-Coated Finish Matters
The black electrophoretic coating provides a uniform dark finish over the 304 stainless steel base material. It is suitable for assemblies where a black fastener appearance is preferred while retaining the wide blind-side support of a tri-fold rivet.
The coating is a surface finish, not a separate stainless steel grade. Appearance and coating durability depend on handling, installation tools, abrasion, surrounding materials and the actual service environment.

Frequently Asked Questions
What does black E-coated mean?
The 304 stainless steel base material is finished with a black electrophoretic coating, also called E-coat, to provide a consistent dark surface and an additional protective layer.
Can these rivets be installed from one side?
Yes. They are blind rivets designed for installation from the accessible side of the assembly.
How do I select the correct grip range?
Measure the combined thickness of the materials being joined, then choose the rivet whose listed grip range includes that thickness.
Is the black coating permanently scratch-proof?
No surface coating should be described as permanently scratch-proof. Coating appearance and durability depend on handling, installation tools, abrasion and the actual service environment.
What pack sizes are available?
Available pack sizes are 50 pcs or 500 pcs. Select the required pack size together with the rivet size.
