Stainless Steel Conical Head Rivet - Grade 202, 304, 316. A2, A2-70

A Conical Head Rivet is a type of permanent mechanical fastener distinguished by its cone-shaped head. This design provides both an aesthetic and functional advantage, offering a sleek surface finish and uniform load distribution. It is commonly used in applications requiring a flush or near-flush surface with strong holding power.

Flat Head Rivet – Technical Specification Table

Here is the Technical Specification Table for Conical Head Rivets:

Parameter	Details
Head Type	Conical (tapered, with smooth or pointed top)

Standard Compliance	ISO 15983, DIN 661, DIN 7338 (where applicable)
Installation Method	Hammering, Rivet Gun, Pneumatic Tools
Surface Fit	Flush or near-flush (for aerodynamic or aesthetic use)

Enhanced aesthetics due to conical, smooth finish
Flush fitting reduces obstruction and drag (ideal for aerodynamic parts)
Good shear strength
Permanent joint—vibration resistant
Sheet metal assemblies
Aerospace and automotive industries
Architectural structures
Electronics casings and enclosures
Furniture and fixtures

Various applications, such as shipbuilding, aircraft manufacturing, automotive production, and bridge construction, make use of these materials. Additionally, they are utilized in the fabrication of electrical components and household appliances. Furthermore, conical head rivets have multiple uses in enhancing structural integrity, attaching metal sheets, and roofing.
