Long grip aluminum blind rivet

[trainguy]

Can anyone suggest a good aluminum blind rivet, in 3/8 or 1/2 inch diameter that will work over a 2 inch grip length? I am hoping for a nice wide bubble at the back end to limit the local stresses on the surrounding aluminum hole.

Huck makes a 1/2 inch aluminum Magna-Lok, but grip is not long enough and Magna-Lok back ends apply very localized loads to hole edges.

The fastener is required for secondary loads in tension, i.e. they are only being used to stabilize a flat plate that is carrying compression against outward buckling.

Thanks.

If you are truly looking for a blind fastener system, rather than a two-piece lockbolt, then you may want to look at Avdelmate® BALMS:

Huck doesn't offer a similar type of fastener. The Huck BOM® and C50L® fasteners have the capability for 2" grip, but BOM® is designed more for steel, and C50L is a lockbolt.

Blind rivets are not well suited for tension loads.

Can you counter bore the back side of the holes in the plate so that you can use a rivet with a short grip length?
