BULBEX® Fastening System
The Bulbex fastening system is a multiple grip all-steel breakstem rivet. Unique crimp design provides wide grip
range and smooth bubble formation on tailside. Available in low profile, large
flange, and countersunk head styles.
Benefits:
- Wide Grip Range
One rivet can be used in multiple material thicknesses, a very unique feature
for an all-steel breakstem rivet.
- Mechanically Locked Stem
Stem is locked in shell, eliminating the risk of mandrel head vibrating
loose while providing a weather resistant joint.
- Complete Hole Fill
The bulbing formation of the Stavex® will fill slightly oversized or
irregular holes, providing increased strength and vibration resistance.
