Come on Carl.....you've been around long enough to know that.
When I was a kid back in the 50's, there were ton and I mean
tons, millions of tons of Army surplus around. darn near every
town had a surplus store and you could buy hardware, likeDzus
fasteners for penny's. I spent a week up at Oshkosh, WI with the
EAA air convention for 20 years running. That's when I was into
the homebuilt airplane fad. There was a HUGE "Fly Market", their
version of a flea market, on the field that ran the whole week. I
used to spend a couple hours a few days I was up there picking
thru the surplus items. I'm just now running low on the Dzus hardware
that I stocked up on.
Yes Gord, EAA and IAC member for a quarter century. Gave it all up
a few years ago. Got tired of chasing a dream. Besides, I flew the daylights
our of the Pitts I built and actually got kind of tire of the whole business and
felt the need to move on to something different. Life's to short to focus on
just one thing for the whole run.
With a lot of searching I've been finding enough info to copy some of the
tools I need. I don't have any of the connections or flying buddies I did
20 years ago, they've all died off by now. My main question was about
The studs that do and do not have the recess. I've finally dug out the
info that I need. When SouthCo acquired DFCI they of course change
all the part numbers pertaining to size, style, etc and it's confused
the selection even more that it was. So, I'm zeroing in on the new
numbers and even found drawings of the setting tools at the old
DFCI site.
Oh, and the sacrilege bit....DFCI was offering a line of fasteners for
automotive use called RaceX for a long time. And they've been used
on almost all professionally built race cars since they flooded the market
after WWII. There's a story about Frank Kurtis out in California blowing
his top when he walked thru the shop and found one of his employees
using them on a new car they were building. Didn't take more than a
few days before all the drawings were changed and all the Kurtis Midgets
were built with Dzus buttons on them.
And Mark....I believe the JIC standard is only for fluid couplings, not
quarter turn fasteners. I offer a quote: "JIC fittings are dimensionally
identical to AN (Army-Navy) fittings, but are produced to less exacting
tolerances and are generally less costly."
Thanks for participating guys,

Oh yes, I might add, I'm using these on the all aluminum body for the
Cyclekart that I'm building, which is a 3/4 scale copy of a Riley Brooklands
grand prix car from the late 20's.
