Name: CherryMAX
Brand: Cherry

Blind (one-sided), pulled-stem blind rivet: “This pulling action causes the stem shear ring to upset the rivet sleeve and form the “bulbed” blind head.” (Cherry CA-1011 (CherryMAX), p.3, Installation)

Shear: 50-75 ksi
Blind bulb: large
Install: One-side install
Diameters: 1/8, 5/32, 3/16, 1/4"
Lead-time risk (SpecLok assessment): Low

Typical applications

·Blind structural joints in metal (CA-1011)

Strengths

+Bulbed blind head: "a large bearing surface area on the blind side" (CA-1011 p.4)
+Driving anvil in each rivet assembly (CA-1011 p.4)
+Locking collar, inspectable after install (PS-CMR-3000)

Trade-offs

−No composite rating in CA-1011
−50 / 75 KSI shear (CA-1011 p.4)

Also called Cherry Max, bulbed blind rivet. P/N: CR3xxx · e.g. CR3242-6-04

Installation verification and preload

Installed preload

Not published. CA-1011 catalog, CA-1015 process manual, and procurement spec PS-CMR-3000 give shear, tensile, fatigue and flushness acceptance only; no preload figure exists for this family.

What to check after install

Stem flushness vs top of head, per diameter (above / below max): -4: .010"/.015"; -5: .010"/.020"; -6: .010"/.020"; -8: .015"/.025" (PS-CMR-3000 Table VIII).
Locking collar flush with top of head within ±.005"; collar flash .010" max.
Blind-side head formation compared against the published acceptable-formation pictorials; stretch marks acceptable.
Grip and material marking on the head must remain readable after install.
Stem may be shaved to the top of the sleeve only if protrusion was within limits first; shaving into the head is not allowed (CA-1015).

Check gauges (3) and sources.Details

269C3 grip selector gage (NSN 5210-00-255-7544): measures stack through the hole before install.
T172 GO/NO-GO hole gages (T172-4/-5/-6/-8 nominal; -400/-500/-600/-800 oversize).
Installed flushness is a dimensional/visual check; no dedicated installed gauge is published.

“Center-punch the stem. This will provide a guide for the subsequent drilling.” Cherry CA-1015 (CherryMAX process manual), p.17, Rivet Removal ↗

“Punch the stem out. Use a steel punch to push the stem out through the blind side.” Cherry CA-1015 (CherryMAX process manual), p.17, Rivet Removal ↗
“Drill out the rivet head. Drill the head using a drill the same size as the rivet shank; be careful not to touch the structure.” Cherry CA-1015 (CherryMAX process manual), p.17, Rivet Removal ↗
“Break off rivet head using a pin punch prying it side to side.” Cherry CA-1015 (CherryMAX process manual), p.17, Rivet Removal ↗

Cautions

“Caution: DO NOT drill completely through the rivet sleeve to remove a rivet as this may enlarge the hole.” Cherry CA-1015 (CherryMAX process manual), p.17, Rivet Removal ↗

None of the removal procedures on file gives a composite-specific removal caution. The Monogram specs address composite at the hole instead: holes "reasonably round and free from burrs (metallic structure) and delamination (graphite/epoxy type structure)" (MBF2003 §5.1).
