Key ProcessesÂ
Blind Rivets
Blind Rivets are multi-piece rivet assemblies capable of being installed from one side of the workpiece. Traditionally, blind rivets were used on aircraft leading edges, trailing edges, and close out areas. Current blind rivet usage has expanded to many additional areas of the aircraft in an effort to decrease labor expense and to address the ergonomic issues of solid riveting.
CherryMAX® "Bulbed" Rivet
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.
CherryMAX® tooling delivers a simple, trouble-free installation. CherryMAX® fasteners are currently available in 1/8" through 1/4" diameters in both nominal and 1/64" oversize diameters. The tools utilize one pulling head to install many diameters, head configurations, and material combinations.
CherryMAX® "AB" "Wiredraw" Rivet
As part of the CherryMAX® family of proven fastener systems, CherryMAX® "AB" rivets are wiredrawing (shank expanding), locked-spindle, flush fracturing, structural rivets meeting the requirements of procurement specification NAS1400 and conforming to NAS1398 and NAS1399 "AB" code standard pages. These rivets provide excellent sheet take up and hole filling performance. "AB" code utilizes non-shift tooling that allows the use of one pulling head for multiple fastener diameters. Use with CherryMAX® tooling.
Cherry® 1900
With the increased use of composites in aerospace structures, the NAS1900 rivet has become a fastener of choice in many designs. The Cherry® 1900 further improves this design with the available Cherry Shift Washer that allows for more consistent fastener installations and extended tool life. This fastener also utilizes the Cherry "One Tool Concept to allow usage of existing tooling. The Cherry 1900 forms a large blind-side footprint that makes it suitable for composite structures. The flush-break capability eliminates the need for shaving. The Cherry 1900 is manufactured to meet NAS1919 and NAS1921 specifications and is available in all sizes and materials.
Cherry SST® Blind Rivet
The Cherry SST® Blind Rivet System was designed to solve many of the blind fastening problems associated with aircraft assemblies requiring superior sheet take-up. Installation of the SST Blind Rivet System ensures consistent and permanent fastening of difficult assemblies with inherent gapping or slightly misaligned holes. The SST Blind Rivet System can be installed with standard CherryMAX® tooling, with no adjustments needed. Eliminate sheet gaps in your toughest assemblies...use the SST Blind Fastening System for superior sheet take-up.

It feature a full range of head styles, diameters and grip lengths for a variety of application requirements. It is available in A-286 CRES, Aluminum and Monel sleeve and stem combinations.
Cherry® Pull Through Nut Plate Rivet
Cherry® Nut Plate Rivets are "pull-through" or "hollow" type rivets. They are used where the high shear strength of the self-plugging type of rivet is not required. This design provides good clamp up and excellent hole filling characteristics, in an inexpensive rivet. This rivet is primarily used in nut plate applications and meets the torque-out and push-out requirements of NASM25027 for nut plates. It is available in mild steel and A-286 stainless steel rivet sleeves, and meets MS20604 and MS20605 requirements.
Cherry TackMax®
The Cherry TackMax® is a blind fastener designed to aid in assembly stack-up and automation. The fastener delivers a high-clamping force during installation to remove any remaining gap between layers. The fastener has also been optimized for automation by providing a high contrast red colored sleeve and tight tolerances on concentricity to the installation hole, allowing the head of the fastener to be a coordinate mark for vision systems. For ease of removal, Cherry TackMax® incorporates anti-rotation features and special fastener ends that serve as built-in drill guides to reduce drill wobble.
The Cherry TackMax was designed around the Cherry One Tool concept. This means that existing single action installation tools from Cherry are capable of installing this fastener. No change in nose-piece is required for most tooling configurations. Consult the Cherry Product Expert for more information.
Cherry® Tacking Rivet
Cherry SPR® 3/32" Self-Plugging Rivet
The 3/32" SPR® Self-Plugging Rivet provides higher strength than pull through rivets, yet still is in the lower price range of nut plate rivets. The Cherry 3/32" SPR blind rivet is ideal for securing nut-plates located in non-accessible and hard to reach areas where bucking or squeezing of solid rivets is unacceptable. Developed to replace solid and pull through rivets in non-structural applications, the unique product design allows for a positive lock to be achieved without an additional lock ring component. Installed with single action tooling, the Cherry SPR stem breaks flush with the rivet head during installation.
Cherry® MS Rivet
Cherry® MS rivets have been a reliable standard of the industry ever since their introduction in 1937. Although superseded in 1960 by the new locked spindle specifications NAS1400 and NAS1740, Cherry MS rivets are still widely used in manufacturing, maintenance, and repair, and meet the qualification requirements of Mil-R-7885 Type II. Cherry® MS rivets are manufactured with serrated stems. The earlier, knob stem configuration is considered obsolete. Cherry blind installation tools may be used to install these rivets merely by changing the pulling head.
Cherry MBC® Rivet
Cherry MBC® is a blind, flush break, locked spindle, structural blind rivet available in aluminum and stainless steel materials. It has a wide grip range, very good joint integrity, high strength-to-weight ratio, and good hole fill. The MBC is available with or without a lock creator. The lock creator feature allows a single pulling head to install different diameters with one pulling head, as in the CherryMAX® type rivet.
