CherryMax® CR3245-4-04 Blind Rivet, 1/8 in Dia, 0.338 in L, 0.22 in Hole Dia, 0.188 to 1/4 in

CherryMAX® is a locked spindle blind rivet with a visibly inspectable mechanical locking device and its own installation washer, which eliminates the problems resulting from worn tool anvils. It is called a bulbed fastener due to its large blind side bearing surface, developed during the installation process. CherryMAX® rivets are used in thin sheet applications and for use in materials that may be damaged by other types of blind rivets. The CherryMAX® rivet is the most reliable, high-strength structural fastener with visual inspectability in the world today. It features the Safe-lock locking collar for more reliable joint integrity and meets the requirements of PS-CMR-3000. CherryMAX® tooling provides the simplest, most trouble-free installation tooling system. CherryMAX® fasteners are currently available in 1/8 through 1/4 in diameters in both nominal and 1/64 in oversize diameters. The tools use a single pulling head to install many diameters, head configurations and material combinations.

FEATURES
• A fully serrated stem with break notch, shear-ring and integral grip adjustment cone
• A driving anvil to ensure a visible mechanical lock with each fastener installation
• A separate, visible and inspectable locking collar that mechanically locks the stem to the rivet sleeve
• A rivet sleeve with recess in the head to receive the locking collar
• A driving anvil is part of each CherryMAX® rivet assembly
• This driving anvil eliminates wear and replacement of expendable installation tool components, considerably extending the life of the installation tool, it also allows a single pulling head to install
• The CherryMAX® rivet features the Safe-lock locking collar which enhances joint integrity and reliability
• The Safe-lock locking collar is preformed on the stem during a sub-assembly operation, then deforms into the rivet sleeve head recess during installation, locking the rivet sleeve and stem together
• The Safe-lock locking collar is visible and inspectable after installation
• The Safe-lock locking collar installs flush with the rivet sleeve head
• The Safe-lock locking collar has been approved by several OEMs for use in engine inlets and components
• Light-weight, non-shifting installation tools require no adjusting
• Limited access capability with right angle and offset pulling heads and extensions for greater reach and Split tools for special applications including automation and robotics
• Bulbed blind head provides a large bearing surface area on the blind side of the structure, giving dependable results, even when installed in difficult thin sheet stack-up applications
