Aluminium Rivet Steel Stem Closed-End Sealed Rivets

Our Closed-End Aluminium Rivets with Steel Stems are sealed blind rivets meeting IFI-126 (Grade 19) specification, designed for applications requiring waterproofing, high shear strength, vibration resistance, and airtight joints. The sealed end prevents fluid or gas ingress through the mandrel hole after installation.

Key Features

• Aluminium body with steel mandrel—combination for corrosion resistance and strength.
• Closed-end (sealed) design ensures the mandrel head is enclosed after setting—reducing leakage and increasing joint integrity.
• IFI-126 / Grade 19 standard.
• High shear and tensile performance.
• Available in multiple diameters and lengths (3.2 mm, 4.0 mm, 4.8 mm body diameters; lengths from ~7.5 mm to ~24 mm).
