DIAMETERS
Bulbed Cherrylock is available in three diameters: -4 (.140); -5 (.173) and -6 (.201). Bulbed Cherrylock
rivet sleeve is 1/64" over nominal size. In most cases the increased bearing area and high strength stem
enables Bulbed Cherrylock to replace solid rivets. The oversize sleeve is also ideal for repair or replacement
of nominal blind or non-blind fasteners of all types. Note: Standard drills are used to prepare installation
holes.
