Oversize countersunk blind rivet
Oversize countersunk blind rivet
(OP)
I'm looking for a 7/32 countersunk rivet.
Material = 2000 series aluminum
Countersunk head = 100 degrees
Something like the NAS1739, NAS1399 or CR3243, but available in 7/32 inches diameter.
I don't want to go to 1/4 due to edge margin concerns.
Thanks for any help.

Have you looked at DIN 65259 sizes say 5.5mm ?

If what You really want is an oversize for a 3/16, take a look at NAS9305E6 [CR3252, 5056-slv + PH15-5-pin, typ CherryMax] or wire-draw Cherrymax [A286 only] CR4652D or CW [hole = 0.205--0.209].

Although those are oversize blind rivets, my hole diameter is 0.225 inches.
As per Boeing spec BAC5004-3, those fasteners are good for a hole diameter of 0.215 – 0.218 inches.
We ended up having to disassemble a bunch of internal structure to install a solid BACR15DS7D (as per Boeing spec BAC 5004-1). It took a lot longer, but it is also permanent.
I'd still like to know of any 7/32 countersink blind rivets for next time.
