Title: Dzus fasteners
Post by: marcmax on February 14, 2011, 11:54:17 AM

Was wondering if anyone on here (possibly one of our aviation inclined members) knows if dzus fasteners are robust enough to use in mounting some Krauser bag frames?

I have seen them used in a lot of racing and aircraft applications but not necessarily what I would consider a load bearing function. The ones I have and was considering using are very stout, approx 1/2" in diameter in stainless.

My r65 is pretty well streamlined and the rear subframe has been modified enough that most of the normal mounting points are no longer there. I don't want to keep the hard bag frames mounted but there are times it would be nice to use the bags. I don't want to be bolting and unbolting ever time I want to use them and think I would use them more if I could "quick release" them.

I was planning on welding on some tabs in strategic places and using the dzus fasteners to accomplish the quick release of the frames. Any comments or suggestions?

I would not use Dzus fasteners where they will have to support any weight. I have seen some break under normal use.

Dzus fasteners are fine for cowlings, inspection panels, etc on aircraft but I would not trust them to secure saddlebags. The bags weight and constant "jiggling" could detach the bag without your knowledge.

My experience with Dzus is that they are a godsend for body panels; ease of removal is paramount when time counts.
There is an entire voodoo technique for selecting the correct fastener :D

Thanks guys. That is what I was looking for as my knowledge of them amounts to removing a few engine cowls a lifetime ago. Back to the planning stage.

Perhaps it's time to add a second bike (R65?) to the stable?  8-)

I already have an 82 LS, am 84 LS and a 90 K75S along with 4 push bikes (bicycles). I am running out of room! It's either thin the herd of build a bigger garage.

The other LS doesn't have bags, I take it.

But surely the K75S does?  That is one of my favorite bikes!
