PRODUCT DESCRIPTION CHERRYMAX® RIVET FEATURES The CherryMAX® rivet is a reliable, high strength structural fastener widely used in the aircraft industry. It features the “safe-lock” locking collar for reliable joint integrity It meets the requirements of PS-CMR-3000. A CherryMAX® rivet consists of four components: 1. A fully serrated stem with break notch, shear ring and integral grip adjustment 2. A driving anvil which acts as a tool, setting the locking collar in place 3. A locking collar that mechanically locks the stem to the rivet sleeve during fastener installation 4. A rivet sleeve CHERRYMAX® RIVET BENEFITS Simple tooling and increased tool life The driving anvil acts as a setting tool increasing the tool life and allowing the installation of multiple sizes (4,5 and 6 diameters) with one tool. Visual Inspectability The CherryMAX® rivet features a “safe-lock” locking collar which enhances joint integrity and reliability. Correct installation can be assessed from the visible side due to two features: stem flushness and locking collar formation. This system is approved for use in engine inlets and components.

FAQs

What are the main components of a CHERRYMAX® rivet?

A CHERRYMAX® rivet includes a fully serrated stem with break notch and shear ring, a driving anvil that sets the locking collar, a locking collar that mechanically locks the stem to the sleeve, and a rivet sleeve.

How does the manual describe the CHERRYMAX® installation sequence?

It instructs inserting the rivet into a prepared hole with the pulling head against the driving anvil, actuating the riveter to form the bulb and initiate shear-ring action, then deforming the locking collar upon contact with the driving anvil so the stem breaks and the top portion is discarded.

How is CHERRYMAX® rivet selection determined from the part numbering system?

The last dash number indicates maximum grip length in 1/16" increments, while the rivet diameter is specified in 1/32" increments; the remaining portion encodes the head style and material combination according to the provided tables.
