Here is the short version: this rivet seals.

Open-end rivets leave a hole through the center. Water gets in. Dust gets in. Air moves through. If that matters to your application, you need a closed-end rivet.

Closed End Dome Head Blind Rivet Al/St gives you a sealed joint without extra steps. No sealant. No gasket. Just a rivet that does two jobs at once.

Quality you can count on

Consistent mandrel break strength
Uniform body expansion without cracking
Smooth, corrosion-resistant finish
Batch testing for shear and tensile strength

The problems this rivet solves

Water penetration through riveted joints is a constant headache for manufacturers of outdoor equipment, automotive components, and enclosures. One leaking rivet means warranty claims, field repairs, and unhappy customers.

Our closed-end rivets eliminate that risk. The aluminum body expands uniformly, the mandrel breaks at the correct strength, and the closed end stays intact. No sealant required. No secondary operation. Just a clean, sealed joint.

Corrosion between aluminum and steel is a real concern. The aluminum body paired with steel mandrel minimizes galvanic issues while maintaining shear strength.
