REFLECTOR: Hardpoints for fasteners

[Keith Hallsten]

For lightweight, non-structural items like wire bundles, fuel lines and
electronic boxes, I have used aluminum bond studs and nylon insert lock
nuts.  Bob Nuckolls had a bunch of #8-32 bond studs that he had found
surplus in Wichita available cheap on his AeroElectric.com website a couple
of years ago.  I don't think he has any more right now, but Click Bond sells
similar items.  

 

Where the application calls for a screw, rather than a stud and nut, I have
drilled a slightly oversized hole through the inner glass, removed the foam
between the inner and outer glass layers to a radius of 1/8" to 3/16" larger
than the inner hole, and filled the void with a stiff flox or microglass.
Once set, I drilled and tapped the "plug" for the size of screw to be used.

Dumb question, and the answer is probably in the manual.  For cable fastener
location for the inside of the fuselage, the factory says to always use a
hard point.  I guess this means even for one screw, ala the photo below.
What's the most effective way to go about this?
