HOW THE BULB-TITE WORKS:
During installation the rivet body folds into three separate
legs, forming the blind-side upset head. The Bulb-tite mandrel
breaks off *flush with the rivet head.
*Flush mandrel break requires use of special Bulb-tite installation
tool nose tip.
WEATHER
TIGHT: A special nose tip on the rivet installation tool
crimps a crown feature on the rivet head. This crown-crimp effectively
seals the rivet bore off from intrusion of dirt and moisture.
Adding the optional washer to the Bulb-tite, creates an additional
seal around the perimeter of the rivet head, to stop moisture
from intruding beneath the rivet head.
HIGH STRENGTH: Another benefit of the Bulb-tite rivetís
retained mandrel core is the added strength it provides. Bulb-tite
rivets are less prone to failure in high shear loads.
HIGH CLAMPING: The large three-legged upset head evenly
distributes the Bulb-tite rivetís high clamp load over a broader
bearing surface than do conventional blind rivets. This enables
soft, thin, ductile and even brittle materials to be securely
clamped without deformation, cracking or other damage to the
application.
HARD-TO-FASTEN APPLICATIONS: Bulb-tite rivets function well
in materials where other fasteners fail. The folded legs individually
conform to curved surfaces enabling fastening onto pipes, corrugations
and other challenging shaped applications. Oversized or elongated
holes can be adequately covered by the large leg formations
to resist pull through under stress in high tension-load applications.
MULTI-GRIP
CAPABILITY: Each Bulb-tite handles a wide variation in material
thickness. Most sizes fasten over a 1/4" thickness range. Fewer
rivet sizes may be required resulting in reduced inventory requirements
and simplified fastener selection.
CHOICE
OF FINISHED APPEARANCE: Bulb-tite rivets are offered in
a variety of head styles. Standard Dome, Low Profile, Large
Flange and Countersunk head styles are available. Color matched
plastic finish caps can be snapped onto certain Bulb-tite head
styles to conceal installed rivet heads. The unique Shaveable
Head Bulb-tite was specifically designed for use in heavy truck
and trailer applications where solid rivets are used. They are
ideal for repair of solid riveted assemblies where access to
the applicationís blind side may be no longer accessible. The
Shaveable Bulb-tite rivet head is finished using a special head-shaving
tool. Shaved Bulb-tite rivet heads then match the appearance
of solid rivets in the assembly.
MATERIAL CHOICES: The standard Bulb-tite rivets are made
of aluminum alloy, providing a durable non-rusting fastener
that can withstand weather-related corrosion. Some Bulb-tite
sizes are also available in steel and monel materials where
higher strength is required
