Determin CR3245 Static Joint Strength Substantiation
Determin CR3245 Static Joint Strength Substantiation
(OP)
I am trying to determine a Static Joint Strength Substantiation for CR3245 Fastener. This is a 'Unisink' fastener made by Cherry Aerospace. It is supposedly equivalent to a NAS9306B, M7885/28, HR3245 or AF3245.
If anyone has any ideas, your help is appreciated. Thanks.

They have tested a bunch of these rivets [various rivet alloys/Dias/grips VS sheet alloys/thicknesses, etc] and have developed MIL-HDBK-5/MMPDS allowables. HOWEVER... MOST of the data is unpublished, because it was generated for a specific OEM customer. Never hurts to ask nicely for a reference copy.
DANG: these blind rivets are my favorites... wish I could get my company to acknowledge/use them.&^%^Y%$$%#$^$^%#@
