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 which are
limited to access to one side of the structure. 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 provides the simplest, most trouble-free installation tooling
system. 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.
Because of 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.
CherryLOCK® "Bulbed" Rivet
Bulbed CherryLOCK® rivets are locked spindle and flush fracturing structural rivets.
They conform to Procurement Specification NAS1740 and standards pages NAS1738 and NAS1739.
Bulbed CherryLOCK® is a complete shear fastening system. Its features can be utilized for optimum strength and performance in both thick
and thin sheets. It provides the highest possible design integrity, particularly in double dimple or thin backside
sheet applications. CherryLOCK® hydroshift installation tool systems are required for installation.
CherryLOCK® "Wiredraw" Rivet
Wiredraw CherryLOCK® Rivets are locked spindle flush fracturing structural rivets with
a wide range of sizes, materials and strength levels. This fastener is especially suited for sealing applications
and joints requiring excellent sheet take-up. It conforms to Procurement Specification NAS1400 and Standard Pages
NAS1398 and 1399. CherryLOCK® hydroshift installation tool systems are required for installation.
CherryLOCK® "A" Nut Plate Rivet
CherryLOCK® "A" is a single action, mechanically locked, wire-drawing fastener that provides excellent
hole-fill and sheet take-up capability conforming to Procurement Specification NAS 1400, and Standard Pages NAS 1398 and NAS 1399.
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.
The Cherry TackMax® is a blind fastener designed to aid in assembly stack-up and automation. The fastener contains several
anti-rotation features that aid in its removal without damaging the structure along, with a high-clamping force during installation
to remove any remaining gap between layers. After installation, both ends of the fastener are designed with removal in mind,
using built-in drill guides on both ends to reduce drill wobble. 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.
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
The Cherry® Tacking Rivet provides simple blind rivet installation and troublefree removal. The Cherry® CCR284 is designed to improve drill-out by
using external splines on the rivet shank to prevent rotation. The Cherry® Tacking Rivet is available with a 5056 aluminum sleeve and a C-1018 steel stem.
Sleeve finishes include clear, red, or black anodize.
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
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.
Chobert® is the original high-speed riveting system used extensively
throughout the fabrication industry for assembly of material, including metals, plastics and ceramics. The Chobert system,
is a mandrel-loaded feed system using one mandrel with multiple rivets loaded in sequence for high
speed riveting. Lightweight fabrications are assembled without damage to these materials, and consistent
performance is achieved every time.
