BULB STRUCTURAL BLIND RIVET DOME HEAD

📌 Overview

The Stainless Steel Bulb Structural Blind Rivet Dome Head is a premium heavy-duty blind fastening solution specifically engineered for high-strength structural applications involving thin sheets, soft materials, composites, plastics, and sandwich panels. During installation, the rivet body expands into a large multi-leg bulb formation on the blind side, creating an exceptionally wide bearing area that distributes the load evenly and minimizes the risk of pull-through.

Featuring a dome (round) head, this rivet provides an attractive finished appearance while delivering superior shear strength, high tensile performance, excellent vibration resistance, and permanent fastening. Its mechanical mandrel locking system securely retains the mandrel within the rivet body, ensuring maximum joint integrity under dynamic loading conditions.

Manufactured from SS304 (A2) and SS316 (A4) stainless steel, or with a stainless steel body and stainless steel locking mandrel, these rivets provide excellent corrosion resistance, long service life, and reliable structural performance in demanding industrial and outdoor environments.

BULB STRUCTURAL BLIND RIVET CSK HEAD

📌 Overview

The Stainless Steel Bulb Structural Blind Rivet CSK Head is a premium heavy-duty fastening solution engineered for high-strength structural assemblies requiring a flush surface finish, exceptional load-bearing capacity, and one-side installation. Featuring a 90° Countersunk (CSK) head, the rivet sits flush with the workpiece after installation, delivering a smooth, professional appearance while maintaining outstanding structural performance.

During installation, the rivet body expands into a large multi-leg bulb formation on the blind side, creating an extensive bearing surface that evenly distributes the clamping load. This design minimizes pull-through and deformation when fastening thin sheet metal, composites, plastics, fiberglass, sandwich panels, and lightweight structures.

The mechanical mandrel locking system permanently retains the mandrel inside the rivet body, significantly increasing shear strength, tensile strength, vibration resistance, and fatigue life.

Manufactured from Stainless Steel SS304 (A2) and SS316 (A4), or with a stainless steel body and stainless steel locking mandrel, these rivets provide excellent corrosion resistance, superior structural integrity, and long-term reliability in demanding industrial, transportation, marine, and construction applications.
